Spirax-Sarco offers valves and accessories for hot water heating systems, such as pressure pilots, vacuum breaker valves, steam control valves, and temperature pilots. Spirax-Sarco control valves are designed to meet every application, helping the system produce clean dry steam for delivery at both high and low pressures.
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.
Spirax-Sarco pressure pilots open and close the main valve by sensing steam flow through them. The pilot valves are controlled by a pressure spring that comes in three pressure ranges: 3 lbs. to 30 lbs., 20 lbs. to 100 lbs., and 80 lbs. to 250 lbs. These pressures are adjustable within their ranges by an adjustment nut on top of the pilot. The pilot has a downstream sensing line which tells the valve to put more pressure on the main valves diaphragm in order to open and allow more steam to pass, as the demand is met, to then decrease the pressure, which relieves the pressure on the main valve diaphragm causing it to throttle to the close position. Spirax-Sarco pressure pilots are suitable for steam applications and offer a wide choice of control options. They can accurately control pressure regardless of variations in upstream pressure and steam load condition.
Spirax-Sarco temperature pilots open and close the main valve by sensing the temperature of the steam. These valves are self-powered. Pilot operation is ideal for applications with constant loads. They are particularly suited for harsh and hazardous environments. Temperature pilots are vital to provide the right temperature for a process, to optimize energy usage, to provide comfort conditions, and for safety.
