RFN 800

RFN 800 series pressure regulator is a direct acting pressure regulator controlled by spring, which is applicable to medium and low pressure gas pressure regulation and non-corrosive gas filtered and purified, such as natural gas.

In addition to being used for gas supply of transmission and distribution pipe network and gas appliances, due to its simple structure, rapid response and high reliability, it is also especially suitable for upstream users (boilers, gas furnaces, etc.) whose pressure often fluctuates due to sharp flow changes.

RFN 800 series regulator is classified according to GB27790, as a regulator which reacts in opening (Fail to Open).
