1 ressure Regulators

2 ressure Regulators is a pilot-controlled pressure regulator for medium and high pressure applications. is normally a fail to open regulator that will open under the following conditions: - breakage of main diaphragm; - lack of pressure feeding to the pilot loop. The gas regulated by the Reflux should be clean, filtered, and non-corrosive.. Modular esign The is modular in design and allows retrofitting of a monitor M/819, slam shut valve and/or silencer in the same body. The regulator is truly a top entry design which allows for easy maintenance and retrofitting options in the field. The unique dynamic balancing control system ensures outstanding turn-down ratio combined with an extreme outlet pressure accuracy. ig. 1 ig. 2 + SIGN WIT YOUR NS IN MIN - ompact esign - Outstanding Turn own Ratio - asy Maintenance - igh ccuracy - Top ntry - Low Operation cost - Low Noise - xtreme lexibility

3 SILNR /819 With decibel noise limitations becoming an increasing safety concern, the silencer option is a unique feature that reduces regulator noise. When the silencer is installed, it allows for a considerable reduction in noise level (da) up to 30 da, depending upon the application. The pressure regulator can be supplied with an incorporated silencer in either the standard version or version with incorporated slam-shut or incorporated monitor regulator. With the built-in silencer, the g and KG valve coefficients are 5% lower than the corresponding version without the silencer. The silencer may be retrofitted to the standard as well as those with an incorporated slam-shut or monitor, without any need to modify the piping. ressure reduction and control operate in the same manner as the standard version. SLM SUT S/82 OR /97 ig. 3 ig. 4 The Reflux 819 O pressure regulator offers the possibility of installing an incorporated slam shut valve S/82 or /97 valve, depending on the regulator size. This can be done either during the manufacturing process or be retrofitted in the field. Retrofitting can be done without modifying the pressure regulator assembly. The g and KG coefficients of a regulator plus incorporated slam-shut system are 7% lower than those for standard versions. The main characteristics of this device are: - intervention for over pressure and/or under pressure - manual re-setting with internal bypass activated by the lever mechanism; - manual push button control; - compact dimensions; - easy maintenance; - optional pneumatic or electromagnetic remote control; - optional installation remote signal devices (contact switches or proximity switches).

4 MONITOR INORORT M/819 SLM SUT ig. 5 ig. 6 + M/819/O + M/819 This emergency regulator (monitor) is directly mounted onto the body of the main regulator. oth pressure regulators, therefore, use the same valve body, although they have indipendent actuators, pilots and valve seats. The operational characteristics of the M/819 monitor are the same as for the regulator The g and KG coefficients of a regulator having an incorporated monitor are 7% lower than those for the standard version. nother great advantage offered by the incorporated monitor regulator is that it can be installed at any time, even on an already existing regulator, without piping modification. This solution allows the construction of reduction lines with compact dimensions. The monitor regulator can either be a M/819/O fail to open regulator (fig. 5) or a M/819 fail to close regulator (fig. 6).

The only difference is that the monitor is set at a higher pressure than the main regulator. The g and KG coefficients of the regulator plus in-line monitor system are about 20% lower than those of the regulator alone. The in-line monitor can either be a fail to open regulator (fig.7) or a Reflux 819 fail to close regulator (fig.8).

Installation of the accelerator is mandatory when the monitor is used as a safety accessory. This device, connected by sensing line to the downstream pressure, discharges the gas enclosed in the motorization chamber of the monitor regulator, allowing the monitor to take over faster. The set point of M/ accelerator is usually higher than the set point of the monitor by 0.66 to 1.10 SIG. In case of working monitor configuration (two stage pressure cut with monitor override), the accelerator may not be necessary.
