Low Pressure Regulator with Indicator Type 541-1

The SRG Indicator Compact Regulator was designed to give you a sufficient Reserve Indication on the remaining level of LPG in your bottle. It will also provide you with the easiest and most realiable way to improve the safety of your Installation by performing a reliable “build in” leaktightness test for your whole installation. Two features in one device!
The body and cover of this regulator form a sealed unit after assembly in order to prevent any external interference which may affect the regulating mechanism.

The integrated “Indictor Gauge” will also act as the ON/OFF Switch.

The regulator can be equipped with a flow limiter which cuts off the gas flow automatically at approx. 1500 l air/hr. (under normal cylinder pressure) in case of a ruptured gas tubing or the gas tubing is pulled off. After cut-off the gas escape is limited to maximum 35 l air/hr.
Regulator inlet with an additional shut-off valve for extra safety.
