Product Specification

Zenith Stainless Solutions offers a full range of high quality air/pressure relief valves.

The Zenith spring-loaded relief valves are commonly used for hygienic pressure relief of a piping system or pump. Hygienic in design and manufactured from 316 stainless steel (304 non-wetted parts), the valve diverts product flow when the product pressure exceeds a manually adjusted set point.

Working Principal:

The metal stem plug of the relief valve is held in the closed position by manually adjusted spring tension. As the pipe line pressure increases beyond the spring’s relief set point, the stem plug is forced open, allowing pressure to be relieved through the discharge port. As the pressure lowers below the spring set point, the plug will return to the closed position.
