Spirax-Sarco #25, 6" 125lb. ANSI flanged main valve only. 250lb. maximum operating pressure. To be used in combination with a pressure pilot for 25P, temperature pilot 25T, both for 25PT or other pilots air actuated, electric, or backpressure. Need to specify type of pilot, pressure range, temperature range, temperature capillary connections and length, etc. See Chart.

Spirax-Sarco cast iron main valves in combination with various type pilots can regulate pressure, temperature, both, backpressure by means of self-actutation, electric, or air pressure pilots. Pressure regulators reduce steam from a high pressure supply to the operating pressure of the equipment. Temperature or combination pressure and temperature regulate temperature in storage water heaters, heat exchangers, air handling coils, tank heating coils, and other temperature control applications where it is necessary to set upper limits on the delivered steam pressure.
