This self-contained, spring loaded diaphragm pressure relief valve is self-operated and requires no air pressure or other outside power source to function. Available in sizes 1/2` through 8` in a wide variety of body materials, linings and diaphragms and with pressure relief settings from 10 to 150 psig. Ideal for applications such as the protection of piping systems of plastic or glass against over-pressure, pipe line surges and water hammer, to isolate equipment which might be damaged by vacuum conditions, to maintain a liquid head in a pump discharge line or to replace or protect rupture discs in hazardous or corrosive processes.

Diaphragm Control Valve for pressure reducing service, back pressure control or pressure relief on application handling de-ionized water, slurries, corrosive or abrasive liquids, or any service which requires a diaphragm type valve. The assembly consists of a No. 630 air-operated diaphragm valve either normally open or normally closed as desired, a No. 60-P pressure pilot and optional No. 1725 chemical attachment, valve positioner and single or dual limit switches. For back pressure control or pressure relief service a pressure sensing line is connected to the chemical attachment on the pressure pilot from a point upstream from the main valve. For pressure reducing service the pressure sensing line must be from a point downstream from the main valve.
