Gas Regulator

Gas pressure regulator (gas pressure regulator) commonly known as pressure reducing valve, also known as gas pressure regulating valve is by automatically changing the gas flow through the control valve, so that the export of gas to maintain the required pressure equipment. Usually divided into direct action and indirect action two.

A regulator is a special type of valve on a gas line that maintains downstream pressure stability regardless of gas flow and upstream pressure variations.
The regulator should be able to: 1. Reduce the upstream pressure to a stable downstream pressure. 2. The regulator should be able to limit the downstream pressure in the event of a fault .
