ERG-SR
Double Stage Gas Regulators
ERG-SR series are double stage gas pressure regulators with OPSO (Over pressure shutoff valve) which offer reliable and accurate pressure regulation for commercial and domestic use.
Approvals
The regulators are designed as per EN 334 & EN 88 standards and undergo over 100 testing points during manufacturing.
Compact Design
Housed in a compact and durable body, the ERG SE is easy to install even in installation sites with space restrictions.
Inbuilt OPSO, SRV and UPSO
In built Over pressure Shut off valve, Safety relief valve and Under pressure shut off valve allow pressure stabilization and automatic line cut off during line pressure and flow fluctuations.
Description
ESKA ERG-SR Series double stage gas pressure regulator is used on gas line to reduce inlet pressure to desired outlet pressure. It is suitable for both commercial and domestic use where it can be directly and easily installed to gas meters with high operational reliability and outlet pressure accuracy. The regulators are manufactured according to Ped Directive 2014/68/EU. The functional tests are performed according to EN334. The regulator consists of OPSO (Over pressure shut off valve), UPSO (Under pressure shut off valve) and Safety relief valve as additional safety features.
The modular concept of ERG-SR and wide range availability of inlet and outlet connections from DN20 to DN50 with different thread standard such as BSP, BSPT, NPT, NPP allow you to customize it as you need.
