Downstream pressure reducing regulator

Code: R514

R514

The Type R512 is a downstream pressure regulator designed for the control of gases and liquids under conditions of low flow. It is constructed to withstand high inlet pressure and will control the downstream pressure of small flowing quantities accurately. Variations from standard valve include special materials to customer’s requirements and cryogenic applications.

Operation

Following a demand for fluid downstream, outlet pressure will fall. This causes a drop in force acting against the spring allowing it to push the diaphragm downwards, thus opening the plug and increasing flow to meet the demand.
