Description
Eska ERG-H6 series pressure regulator is used on gas line to reduce inlet pressure to desired outlet pressure. It is mainly used in Distribution of Natural Gas and also suitable to use with non-corrosive gases. ERG-H6 is a single stage direct acting regulator with a optional security systems such as relief valve UPSO and OPSO Monitor version is also available.
Relief System
Regulator can be produced with a relief valve. Relief valve monitors outlet pressure continuously and when it detects pressure level higher than regulator’s nominal outlet pressure, it activates and discharges gas to the atmosphere. Relief valve has limited discharge capacity. Usually calibration point is lower than OPSO system.
Under certain conditions such as gas expansion during hot weather seasons, Relief Valve is activated before OPSO closes the gas lines. It prevents random shut-off regarding pressure increase on outlet side. Relief valve can be recalibrated by using proper tools.
Over Pressure Shut-Off System
OPSO system is very useful during major breakdown situations and keeps the customer side safe. System works as a security valve and activates itself when the outlet pressure passes OPSO calibration point. OPSO system cuts the gas off, and manual reset is needed to activate the regulator again. System has an independent shut-off mechanism and orifice and it monitors outlet pressure changes continuously, so activation time is below 2 seconds.
