REXI - Direct acting pressure regulator

The RG Series is a direct-acting pressure regulator with balanced plug, for low, medium and high pressures. Suitable for non-corrosive gases; thanks to the concept of a balanced plug, you can achieve a high flow rate coefficient,highly accurate (even at maximum flow rates), a lock up zone and relatively low lock up pressure, no internal leakage atzero flow rate and reduced response times.

The constancy of the regulated pressure and its accuracy, even with significant changes in the upstream pressure and/ or flow rate, make the RG Series regulator especially suitable for power distribution networks in civil and industrial plants. The basic version of the RG Series regulator is made according to European Standard EN 334, as a Fail to Open regulator

The shut-off device can be calibrated for pressure increase, Over Pressure Shut-Off (OPSO) and/or for pressure decrease, Under Pressure Shut-Off (UPSO). The two intervention modes can be calibrated independently by dedicated calibration springs: one spring for the maximum pressure intervention and the second spring for the minimum pressure intervention. RG series can be supplied also without Slam Shut valve.

The RG Series can be equipped with an incorporated relief valve that discharges the gas into the atmosphere when

the regulator outlet pressure exceeds the set value. When the outlet pressure returns to below the set value, the relief valve closes again.

The MONITOR is a safety accessory that performs the functions of the service regulator when the main regulator fails. This is a regulator valve that is usually fully open during normal operation of the service regulator. The MONITOR is an emergency pressure regulator that is usually upstream, in the direction of the gas flow, of another pressure regulator that performs the function of a SERVICE regulator.
