Spirax-Sarco pressure reducing valves reduce steam pressure when it is needed at the point of use. Spirax-Sarco offers both pneumatic signal and actuator operated valves that automatically reduce high initial pressure to lower delivery pressure. They are suited for installations in pressing irons, steam cookers, sterilizers, or any steam applications requiring reduced pressure. Pressure can be changed by removing pin and turning the adjustment screw clockwise to increase, and counter-clockwise to decrease the delivery pressure.
