Self Acting, Pilot & Piston operated Steam Pressure Reducing Valve are most popular for pressure reduction of STEAM in all types of Industries. The Valve operates on Spring Balance principal.
The Downstream pressure is sensed below stainless steel diaphragm which is balanced by the spring tension. Increasing spring tension, increases outlet pressure and vice versa. The Valve has additional external sense Line provision also, which improves performance and accuracy of outlet pressure.
