COVNA Pilot Operated Steam Pressure Reucing Valve

This series of the valve falls within the category of pilot-piston operated pressure reducing valve. It is composed of main valve and auxiliary part. The main valve includes: valve seat, main valve disk, piston, piston springs and others. The pilot part includes valve seat, valve disk, diaphragm, spring, adjusting screws and others.

The valve throttles through the adjusting spring, and reduces the inlet pressure to a needed outlet pressure. It makes use of the energy of the medium itself so that the outlet pressure automatically meets the predetermined requirement to achieve the function of pressure relief.
