ERG-SE Series

ERG-SE DOUBLE STAGE PRESSURE REGULATOR (Opso Upso)
 
ERG-SE is a self-operated dual-stage and double safety pressure regulator for use with natural gas, LPG and non-corrosive gases.
It guarantees the power supply of the connected appliances starting from a medium pressure distribution network (0.5 - 5 bar).
The modular concept of the ERG-SE together with the availability of a wide range of input and output connections, guarantee a response to every specific customer need.
 
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 ori fice and it monitors outlet pressure changes continuously, so activation time is below 2 seconds.
 
UPSO system on ERG- SE series regulator acts under those circumstances; • When there is no pressure inlet side. • When the consumption exceed regula - tor’s maximum capacity. (%101*Q to %150*Q) • When the pressure drop outlet side due to consumption. UPSO valve continuously monitors outlet pressure changes. Scenarios like, pipeline breakdown on outlet sides, or consump - tion is exceeding the total capacity of regu - lator or lack of inlet pressure situations etc…the outlet pressure drops and the regulator cuts the gas off once UPSO system is activated.
