ESKA ERG-H7 direct acting gas pressure regulator is used on gas line to reduce inlet pressure to desired outlet pressure. H7 series is mainly used in distribution of Natural Gas but also suitable for non corrosive gases. Monitor version is also available. The regulators are manufactured according to Ped Directive 2014/68/EU. The functional tests are performed according to EN334.
The ERG H-7 can be equipped with an inbuilt OPSO (Slam shut off valve) which 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. Inbuilt Safety relief valve and UPSO are some other integral features of this regulator.
ERG-H7 Series gas pressure regulator body consists of:
Valve housing
Furthermore the truly “top entry design” allows an easy periodical maintenance without removing body from the line as well as High flow rate coefficient, High accuracy, even at maximum flow rates, Reduced response times.
Housed in a compact and durable body, the ERG H-7 is easy to install even in installation sites with space restrictions
The regulators are designed as per EN 334 & EN 88 standards and undergo over 100 testing points during manufacturing
In built Safety relief valve & Over & Under pressure shut off valve allow pressure stabilization & automatic line cut off during line pressure & flow fluctuations.
