Tri-Clover® D60RTHMP Relief Valve

Central States Industrial (CSI) offers the Tri-Clover® D60RTHMP relief valve from Alfa Laval. These spring-loaded relief valves are commonly used for sanitary pressure relief of a piping system or pump.

Sanitary in design and manufactured from stainless steel, the D60RTHMP diverts product flow when the product pressure exceeds a manually adjusted set point.

D60RTHMP is available with one of several springs for relief pressures ranging from 5 psi to 85 psi.

WORKING PRINCIPLE

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.

The compression valve is operated by means of a "tee" handle turning mechanism. This allows the valve to gradually open and close.
