Dome Loading Down-stream Pressure Regulation

We provide a range of either standard locked or variable pilot pressure dome loading, down-stream pressure controller ranges. Suitable for both liquid or gas service these regulators can either be set-up from an external source, (such as a separate gas bottle), or directly loaded from up-stream inlet gas pressure. Pilot loading can be from a fixed or a variable pressure source depending upon required down-stream performance.
We are able to supply models suitable for N.A.C.E, HIGH PURITY orOXYGEN service but please always specify this requirement with your enquiry or when placing an order.
