Rotork Self Acting, Pilot & Piston operated Pressure Reducing Valves are most popular for pressure reduction of STEAM in all types of Industries. The Valve operates on Spring Balance principle.
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.
