3/4 NPT CONTROL LINE W77-1_07/ W78-1 Type 99H WITH EXTERNAL REGISTRATION Type 99HR PILOT WITH OPTIONAL TOKEN RELIEF Figure. 99H Series Sectional Views Features Compact in Size Small envelope because of the built-in pilot and internal registration. Unique No Bleed Monitor System Flexible worker/monitor system setup that allows for bleed to be piped to the intermediate piping thus eliminating downstream bleed which reduces lost and unaccounted for gas. Another advantage of this configuration is that the system lockup pressure is that of the worker instead of the monitor. Not an Adaptation of Existing Regulators New design of integrated cases and internal registration ports. Wide Variety of Applications Natural gas distribution systems, gas supply to industrial boilers, furnaces, ovens, mixers, plant air service. Highest Quality Designed and manufactured to ISO 9001 standards. Accuracy Keeps constant inlet pressures to downstream equipment by accurately controlling distribution system pressures at widely varying flow rates and supply pressures for maximum efficiency and best operation or by eliminating the need for pressure-compensating meters by holding a steady pressure to the meter inlet. Optional Token Relief The Types 99HR and 99HVR with an integral token relief in the pilot is designed to relieve minor overpressure caused by thermal expansion. High-Capacity Pressure Control Actuator diaphragm responds quickly to downstream pressure change, causing immediate correction in main valve position. Pilot responds simultaneously and controls final positioning of main valve. This action permits full main valve travel, resulting in higher capacity than could be obtained without an external pilot regulator. Easy Registration Conversion Two screws and O-rings change internal registration to external or dual registration. Easy Startup No special procedure required. Easy to Maintain Main valve disk and orifice can be inspected without removing body from pipeline. Easy access two bolt flange permits quick removal of actuator and pilot from body. Economical, Labor-Saving Installation Supply pressure to pilot is factory-piped directly from inlet side of main regulator body, thus requiring no upstream pilot supply line on standard installations. Rugged Construction With a two bolt connection of the regulator to the body and no union ring, the 99H Series regulators are designed for longer service life with minimal maintenance requirements. No gaskets Reusable O-rings at all serviceable joints. 3

Fewer Parts Fewer recommended parts needed for spare parts inventory. Introduction Description! Warning Since a pilot-operated regulator is constructed of both a pilot and a main valve, do not exceed the maximum inlet pressure shown on the nameplate. The 99H Series pressure reducing regulators provide a broad capacity of controlled pressure ranges and capacities in a wide variety of distribution, industrial and commercial applications. A 99H Series regulator has a pilot integrally mounted to the actuator casing. The 99H Series regulators can handle inlet pressures up to psig / bar depending on orifice size. The integral token relief on the Types 99HR and 99HVR regulators is located in the pilot and alerts you to an increase in downstream pressure beyond the regulator setpoint. The Type 99HV provides overpressure or overpressure and underpressure protection by completely shutting off the flow of gas to the downstream system. It comes with a Type VSX8 (99HV) slam-shut device which can be configured for Ovepressure Shutoff (OPSO) or Overpressure and Underpressure Shutoff (OPSO/UPSO). The slam-shut device s actions are independent of the main valve and of variations to the inlet pressure. The Type VSX8 (99HV) slam-shut device has internal or external registration. External registration requires a downstream sensing line. Options P90 Series Pilot Supply Filter The optional P90 Series pilot supply filter prevents pipeline debris from entering the pilot; a primary cause of pilot clogging. When the upstream system is free of debris, the 99H Series regulators may be installed without a pilot supply filter. Type 67CF Filtered Pilot Supply Regulator When it is necessary to install a pilot supply regulator, an optional Type 67CF filtered pilot supply regulator may be installed. For example, on applications with in. of water column setpoints and inlet pressure variations of more than ± psig / ± bar it may be necessary to install a Type 67CF to maintain published accuracy. 4

Reed Switch An optional remote notification switch can be installed offering the capability to remotely notify the operator should VSX8 Series shut off occur. Reed switch is available on our regulators 99HV and 99HVR Series only. Reference D317X01 for instruction manual. Principle of Operation Letter keys in this section refer to Figure 3 unless otherwise noted. Fast response and accuracy are made possible by the amplifying effect of the pilot and by the two-path control system. The function of the pilot is to sense change in the controlled outlet pressure and amplify it into a larger change in the loading pressure. Any changes in outlet pressure act quickly on both the actuator diaphragm and the loading pilot, thus providing the precise pressure control and fast speed of response that is characteristic of a two-path system. Upstream or inlet pressure is utilized as the operating medium, which is reduced through pilot operation to load the main diaphragm chamber. Tubing connects the inlet pressure to the pilot. Downstream or outlet pressure registers underneath main diaphragm (E) and on top of pilot diaphragm (F). There are three different versions of pressure registration for the Type 99H. Internal registration (screws and O-rings (J) removed) Outlet pressure is registered through the throat to the main diaphragm chamber and through a small port (G) to the top of the pilot diaphragm. Internal registration is used for ease of installation. Capacity is somewhat limited because of droop and/or boost associated with sensing pressure within the body. External registration Screws and O-rings (J) block the throat and a downstream control line is connected to the pilot diaphragm chamber which is connected to the lower main diaphragm chamber by a small port (G). The other end of the control line connects to the downstream pipeline. External registration is used for higher capacity and/or the upstream regulator in a monitor set. It also allows monitoring for inlet pressures over 66 psig / 4. bar. Capacity is increased because of better registration of pipeline pressure when a control line is used. The alternate 3/4 NPT control line connection (on the side of the pilot) can be used for piping convenience, see Figures 8 and 9. Dual registration (screws and O-rings (J) removed) The lower main diaphragm chamber registers outlet pressure through the throat and the pilot diaphragm chamber registers downstream pressure by use of a downstream control line. The port (G) between the chambers is blocked by inserting a screw and O-ring (J) that was removed from the throat and the control line runs from the pilot to the downstream pipeline. Dual registration, with its larger orifice (control line must be piped to the primary 3/4 NPT connection on the side of the pilot), provides an improved performance as compared to internal pressure registration when used in low flow rate and high pressure drop applications. It is also used for no downstream bleed monitoring systems with inlet pressures up to 66 psig / 4 bar. Type 99H In operation, assume the outlet pressure is less than the setting of pilot control spring (A). The top side of pilot diaphragm assembly (F) will have a lower pressure than the setting of spring (A). Spring (A) forces the diaphragm assembly upward, opening the pilot orifice (C). Additional loading pressure is supplied to the top side of the main diaphragm (E). This creates a higher pressure on the top side of main diaphragm (E) than on the bottom side, forcing the diaphragm downward. This motion is transmitted through a lever, which pulls the valve disk (K) open, allowing more gas to flow through the valve. When the gas demand in the downstream system has been satisfied, the outlet pressure increases. The increased pressure is transmitted through the downstream control line (for external or dual registration) or through the port (G) (for internal registration) and acts on top of the pilot diaphragm (F). This pressure exceeds the pilot spring setting and forces the diaphragm down, closing the orifice (C). The loading pressure acting on main diaphragm (E) bleeds to the downstream system through a bleed restriction (H). With a decrease in loading pressure on top of main diaphragm (E), main spring (B) exerts an upward force on the diaphragm post connected to main diaphragm (E), pulling it upward. This moves the main valve disk (K) toward its seat, decreasing flow to the downstream system. 7

Type 99HR Refer to Figure 4. The Type 99HR provides an integral token relief valve. During an overpressure condition the spring on the pilot post will allow the diaphragm head to travel to the spring case. As the diaphragm head moves a small amount of gas is relieved. Note The Type 99HR is not a full capacity relief device. Approximate start-todischarge pressure is dependent on set pressure, see Figure 7. During normal operation the Type 99HR performance is identical to the Type 99H. If an overpressure condition occurs, the pilot diaphragm head will separate from the pilot diaphragm post and travel until it contacts the pilot spring case. The movement of the diaphragm head creates a path and a token or noticeable amount of gas will be released. When the overpressure condition ceases, the pilot diaphragm head will return to the diaphragm post and the regulator will return to normal operation. Type 99HV Refer to Figure. The Type VSX8 (99HV) slamshut devices on the Type 99HV regulator is a fast acting slam-shut valve which provides overpressure or overpressure and underpressure protection by completely shutting off the flow of gas to the downstream system. The slam-shut modules actions are independent of the Type 99HV main regulator and of variations to the inlet pressure. The Type VSX8 (99HV) has internal or external registration. External registration requires a downstream sensing line. The slam-shut disk is held in the open position (reset position) by an internal latching mechanism that holds the valve stem and disk assembly. If the pressure below the diaphragm increases (or decreases) reaching the Type VSX8 (99HV) setpoint, the diaphragm will travel upwards (or downwards) operating a lever which in turn releases the valve stem assembly. Once released, the spring force on the stem will push the stem and disk to the closed position against the seat shutting off all gas flow. The pilot supply pressure is also shut off when the Type VSX8 (99HV) is closed. The manual reset has an internal bypass to equalize the reset pressure on either side on the slam-shut disk. In order for the Underpressure Shutoff (UPSO) of any slam shut to be triggered, the downstream pipe pressure must drop below the UPSO setpoint. In the case of a downstream line break, numerous factors can prevent the downstream pipe pressure from decreasing below the slam-shut UPSO setpoint. These factors include the distance of pipe to the break, the diameter of the pipe, size of the break and the number of restrictions, such as valves, elbows and bends, downstream of the regulator and/or slam-shut device. Due to these factors additional protections should be installed to stop flow in the event of a line break. Overpressure Protection Like most regulators, the Type 99H has outlet pressure ratings lower than the inlet pressure ratings. Complete downstream overpressure protection is needed if the actual inlet pressure exceeds the outlet pressure rating. Overpressure protection for internal parts is built into the main and pilot diaphragms by means of a small spring on each post. The springs will allow the diaphragm heads to move farther on the posts avoiding damage to or bending of the valve trim. Overpressuring any portion of a regulator or associated equipment may cause leakage, parts damage or personal injury due to bursting of pressurecontaining parts or explosion of accumulated gas. Regulator operation within ratings specified in the Specifications section and on the regulator nameplate does not preclude the possibility of damage from external sources or from debris in the pipeline. A regulator should be inspected for damage periodically and after any overpressure condition. The pilot vent is provided with a 1/4 NPT tapped connection in the spring case. 9

Monitoring Systems Monitoring regulators serve as overpressure protection devices to limit system pressure in the event of open failure of a working regulator feeding the system. Wide-Open Monitor The control line of the upstream regulator is connected downstream of the second regulator (Figure 6), so that during normal operation the monitoring regulator is standing wide open with the reduction to distribution pressure being taken across the working regulator. Only in case of open failure of the working regulator does the wide-open monitoring regulator take control at its slightly higher setting. A pressure build-up above the monitor set pressure is required for the monitor to take control in the event of an overpressure situation. Installing a pilot supply regulator on the monitor will minimize the pressure build-up. The pilot supply regulator should be set to 3 psig / 0.1 bar above the monitor setpoint. The minimum set pressure difference between the worker and monitor should be greater than the proportional band. Small set pressure differences may cause the worker and monitor to function independently. The upstream regulator can easily be field converted or ordered with screws and O-rings in the throat (Figure 6). This seals off the path that otherwise would let line pressure ahead of the working regulator inlet and try to close the wide-open monitoring regulator. No Downstream Bleed Monitor The no bleed monitor is a wide-open upstream monitor which works like a conventional wide-open upstream monitor except for registration. The no bleed monitor utilizes a dual registration construction as opposed to the external registration construction of the conventional monitor. This ensures that the lockup of the monitor system is the lockup of the downstream working monitor at zero flow during normal operation. Installation Although the actuator and pilot can be mounted in 90 increments relative to the body, the normal installation is with the body in a horizontal run of pipe and the pilot hanging vertically from the bottom of the actuator. Control and vent lines necessary for installation are not supplied with a Type 99H regulator. Control and vent connection locations are shown in Figures 8 and 9. In many instances good piping practice will require that outlet piping be swaged up above the body size to prevent excessive pressure drop along the outlet line. The piping should be expanded as close to the regulator outlet as possible. Capacity Information Tables through give the 99H Series natural gas regulating capacities at selected inlet pressures and outlet pressure settings. Flows are in scfh ( F and 14.7 psig) and Nm³/h (0 C and 13 bar) of 0.6 specific gravity natural gas. To determine equivalent capacities for air, propane, butane or nitrogen, multiply the capacity number in the Tables by the following appropriate conversion factor: 0.77 for air, 0.68 for propane, 0.48 for butane or 0.789 for nitrogen. For gases of other specific gravities, multiply the given capacity by 0.77 and divide by the square root of the appropriate specific gravity. For critical flow: To determine wide-open flow capacities for relief sizing of 0.6 specific gravity natural gas at F at critical pressure drops (absolute outlet pressure equal to approximately one-half or less than one-half of the absolute inlet pressure), use the following formula: Q = P 1(abs) (C g )(1.9) For subcritical flow: If pressure drops are lower than critical (absolute outlet pressure greater than approximately one-half the absolute inlet pressure), use the following formula and convert according to the factors in the preceding paragraph if necessary: Q = GT C g P 1 SIN 3417 C 1 P P 1 DEG where: C 1 = C g /C v (see Table 3) C g = Gas sizing coefficient (see Table 3) G = Gas specific gravity (air = ) P 1 = Regulator inlet pressure, psia P = Pressure drop across regulator, psi Q = Gas flow rate, scfh T = Absolute temperature of gas at inlet, Rankine Note Due to boost, the above formulas cannot be used to obtain correct regulating capacities for regulators with internal registration. The published capacities were obtained using inlet and outlet piping the same size as the regulator body size. 13
