1 B Series Regulator Twin Parallel Commercial Regulators Use the B for light utility, industrial and commercial application. The twin parallel design should be used where a high degree of safety and overpressure protection are required such as schools, hospitals and community centers. This regulator is an excellent replacement for parallel regulator piping systems. MODEL DESCRIPTIONS»» BN The BN is a spring loaded self operated regulator with no internal relief. This regulator can be used on low or intermediate inlet pressures where an internal relief valve is not required.»» BR The BR is the internal relief version of the BR Series. This model features twin internal relief valves. Due to its excellent relief characteristics, the BR can be used on any inlet system up to the regulator s maximum operating pressure rating.»» BIMN (See page Schematic) The B IMN is equipped with an internal monitor (IM) orifice that operates upon failure of the main valve. The N designation signifies no internal relief valve.»» BIMR (See page Schematic) The BIMR is equipped with an internal monitor (IM) orifice as a primary form of overpressure protection that operates upon failure of the main valve seat. The BIMR is also equipped with secondary twin internal relief valves open in the event that both the main seat and the internal monitor cannot function.»» BIMRV (See page Schematic) The BIMRV is equipped with an internal monitor (IM) orifice as a primary form of overpressure protection that operates upon failure of the main valve. It is also equipped with the vent-hole V option which gives a warning indication that the regulator is on monitor control in the event of main valve failure. The venthole V option consists of a /6 hole in the sliding orifice that allows a small amount of gas to bleed downstream which causes the relief valves to weep gas. In the unlikely event the main valve and the monitor valve fails to function, the BIMRV is equipped with secondary or back-up twin internal relief valves. Option Designations N No internal relief R Internal relief IMN Internal monitor without internal relief IMR Internal monitor with internal relief IMRV- Internal monitor with internal relief and vent FEATURES»» Interchangeable brass orifice»» Combined 4 in of diaphragm area»» Twin Spring-loaded internal relief valve assemblies»» Field interchangeable adjustment springs»» No special adjustment tools required»» Controlled size breather orifice eliminates pulsation and provides normal actuation at low flows»» Wide range of valve body sizes BENEFITS»» Eliminates parallel regulator piping installations»» Light weight»» Fast response protects equipment from shock damage»» Field inspection of the internal monitor and internal relief valves without customer shut-off or by-pass»» Unmatched overpressure protectin with internal monitor plus internal relief options SPECIFICATIONS sales@mvandc.com Phone: Fax:

6 CORRECTION FACTORS FOR NON-NATURAL GAS APPLICATIONS The B may be used to control gases other than natural gas. To determine the capacity for gases other than natural gas, multiply the values within the capacity tables by a correction factor. The table below lists the correction factors for some of the more common gases: Gas Type Specific Gravity Correction Factor (CF) Air Butane.0 0. Carbon Dioxide (Dry). 0.6 Carbon Monoxide (Dry) Natural Gas Nitrogen Propane. 0.6 Propane-Air-Mix To calculate the correction factor for gases not listed in the table above, use the gases specific gravity and insert it in the formula listed below: Correction Factor (CF) = Where: SG = Specific gravity of the gas in which the capacity is published. SG = Specific gravity of the gas to be controlled. Wide Open Flow Calculations For wide-open orifice flow calculations use the following equations: For use: For use: Where: P = Absolute Inlet Pressure (PSIA) P = Absolute Outlet Pressure (PSIA) Q = Flow Rate (SCFH) K = Orifice Coefficient (SCFH/PSI) sales@mvandc.com Phone: Fax:

19 B COMMERCIAL REGULATOR IM MODELS A. Normal regulation B. Normal lock-up D. Single monitor operation, one full internal diaphragm case failure C. Dual monitor operation - internal foreign material failure E. Internal monitor lock-up PRINCIPLE OF OPERATION a. Normal Operation. The internal monitor (IM) orifice performs like a standard one-piece orifice, performing normal regulation. The upstream monitor remains wide-open. b. Normal Lock-up. The regulator is free to lock-up in the usual manner. A nitrile o-ring forms a seal between the stationary and sliding orifices and prevents gas from leaking past the outer part of the orifice into the downstream or low pressure side of the valve body. The upstream monitor remains wide open. c. Monitor Operation. The monitor is comprised of one sliding orifice with a brass sharp edge and another sliding orifice with a vulcanized nitrile valve seat. If either of the regulator s main valves fails to lock-up for any reason, the internal monitor orifice automatically goes into operation. Outlet pressure increases slightly, causing the valve seat to push against the inner or sliding part of the orifice, gradually compressing the monitor spring and closing the secondary or monitor orifice on the inlet side of the sliding orifices. At this point, the BIM operates as a monitor regulator. C. Foreign material failure. Assume a weld bead is caught between the orifice and the valve seat while in high flow operation. If the flow is reduced, the main valve tries to close, but cannot due to the foreign matter. The outlet pressure increases approximately " w.c. above the original set point (varies based on main valve set point) which starts to close the secondary monitor orifice. If the gas demand is decreased, the monitor will be partially closed and becomes the new operating orifice. It will function as a monitor regulator keeping the outlet pressure approximately " w.c. above the set pressure for set pressure < PSIG or 0. PSIG for set pressure > PSIG. C. Diaphragm or lever failure. While diaphragm or lever failure is an entirely unlikely situation, if the event would happen, the damages side of the regulator will be unable to operate. The outlet pressure will then increase on the functional regulator and its sliding orifice moves to contact the monitor orifice and seat. However, since only one diaphragm is in operation, the outlet pressure will be about 4" w.c. higher on monitor operation than the normal set point. d. Monitor Lock-up (no demand). If the demand for gas downstream of the regulator is zero, the sliding orifices or orifice will close against the secondary rubber monitor seat and stop the gas flow completely. e. Vent-hole "V" Option (not shown). The sliding orifices of the IMRV model are equipped with 0.049" vent holes located near the sliding orifice s stepped portion. During monitor operation, if the demand is very small or non-existent, the 0.049" vent holes will allow gas to bleed from the high-pressure inlet side to the low-pressure outlet side of the regulator. The pressure will build until the internal relief valve cracks. The relief valve will weep gas to the atmosphere giving a warning indication the regulator is not operating properly. f. Regulator and Monitor Failure (not shown). In the unlikely event both the regulator and monitor fail, the BIMR is equipped with twin internal relief valves that will be actuated by the stop stem.

VENT LINES FOR REGULATORS When constructing vent lines to be attached to regulators installed indoors, follow a few basic rules: a. b. c. d. e. f. g. h. Never use pipe sizes smaller than the vent size; smaller pipe sizes restrict the gas flow. If a long gas run must be used, Itron advises increasing the pipe one nominal size every ten feet to keep the flow restriction as low as possible. Keep the vent line length as short as possible to minimize the restriction and reduce the vent's tendency to cause regulator pulsation. Support the vent pipe to eliminate strain on the regulator diaphragm case. Always point outdoor vent pipes in the downward position to reduce the possibility of rain, snow, sleet, and other moisture entering the pipe. Install a bug screen in the end of the pipe. Do not locate the vent line terminus near windows, fans, or other ventilation equipment. See the installation instructions furnished with the regulator. Adhere to all applicable codes and regulations. If your vent pipe causes regulator pulsation, consult your sales representative or manufacturer. Itron strongly recommends running a separate vent line for each regulator. Headers with various installed devices can cause regulator malfunction. Caution Ensure the end of the vent line is away from ANY potential ignition sources. It is the installer s responsibility to verify the vent line is exhausting to a safe environment. sales@mvandc.com Phone: Fax:
32 INSTALLATION Warning Itron does not endorse or warrant the completeness or accuracy of any third party regulator installation procedures or practices, unless otherwise provided in writing by Itron. Follow your company's standard operating procedures regarding the use of personal protection equipment (PPE). Adhere to guidelines issued by your company in addition to those given in this document when installing regulators. a. b. c. d. e. f. g. Remove all shipping plugs from the regulator inlet, outlet, and vent before installation. Verify the piping interior and regulator inlet and outlet are clean and free of dirt, pipe dope, and other debris. Dirt and other foreign materials entering the regulator can cause a loss of pressure control. Apply pipe joint sealant to the male pipe threads. Do not use pipe joint material on the regulator's female threads. Joint sealant could become lodged in the regulator and cause a loss of pressure control. Gas must flow through the regulator's valve body in the direction cast on the regulator body. Gas flowing in the wrong direction can overpressure and cause damage to the regulator. The pilot diaphragm casing can be mounted in any position relative to the body through a full angle at 90 increments. When the regulator is installed OUTDOORS, the vent must always be positioned so that rain, snow, moisture or foreign particles cannot enter the vent opening. Itron recommends positioning the pilot vent downward to avoid entry of water or other matter which could interfere with the proper operation of the regulator. The vent should be located away from building eaves, window openings, building air intakes and above the expected snow level at the site. The vent opening should be inspected periodically to insure it does not become blocked by foreign material as outlined in DOT PHMSA-RSPA When the regulator is installed INDOORS, the vent must be piped to the outside atmosphere using the shortest length of pipe, the fewest possible pipe elbows, and a pipe diameter as large as the vent size or larger. USING VENT PIPE SMALLER THAN THE VENT CONNECTION LIMITS THE REGULATOR S INTERNAL RELIEF VALVE CAPACITY. The outlet end of the pipe must be protected from moisture and the entrance of foreign particles. The regulator should be specified by the user with the size vent and pipe threads desired to make the vent pipe connection. START-UP PROCEDURE a. b. c. d. Mount a pressure gauge downstream of the regulator to monitor the downstream pressure. With the downstream pressure valve closed, slowly open the inlet valve. The outlet pressure should rise to slightly more than the setpoint. Verify there are no leaks and all connections are tight. The regulator was pre-set at the factory to match order specifications. If necessary, adjust the outlet pressure by removing the seal cap on the top of the pilot spring housing and adjusting the ferrule or screw inside the pilot spring housing using a large flat-head screwdriver. With a small amount of gas flowing through the regulator, rotate the pilot ferrule clockwise to raise the outlet pressure or counter-clockwise to lower the outlet pressure. Replace the seal cap and check for leaks after the desired outlet pressure is achieved. The regulator is ready for operation. SAFETY WARNING This product, as of the date of manufacture, is designed and tested to conform to all governmental and industry safety standards as they may apply to the manufacturer. The purchaser/user of this product must comply with all fire control, building codes, and other safety regulations governing the application, installation, operation, and general use of this regulator to avoid leaking gas hazards resulting from improper installation, startup or use of this product. Itron strongly recommends installation by a qualified professional and periodic inspection of pressure regulators (inspections may be required by local applicable codes or regulations). Inspections should include checking for gas quality, cycle numbers, external environmental changes, and operating conditions that impact wear on the regulator's moving parts. To ensure safe and efficient operation of this product, replace worn or damaged parts found during inspection. sales@mvandc.com Phone: Fax:
