Quality is everything! US Walker (WORK) imports pilot solenoid valves are suitable for steam as the heating medium, temperature control of the executive body. Steam boiler steam pipes can heaters, radiators, steam dryers and other equipment and various types of temperature-controlled instrument, steam setting machine, steam dyeing machines, steam resurgence of machines and other equipment were two automatic control and remote-controlled areas. Widely used in dyeing, textile, printing and dyeing, food, medicine, cigarettes, cement products, petrochemicals, metallurgy and other sectors of the automatic control system. How it works: When energized, the electromagnetic force the pilot hole is opened, the chamber pressure decreased rapidly around the closure member is formed on the lower high pressure, fluid pressure pushes the closure member is moved upward, the valve opens; when de-energized, the spring force of the pilot hole is closed, the inlet pressure chamber through the bypass hole quickly shut the valve member is formed around the low pressure on the high fluid pressure pushing off pieces to move down, close the valve. Action time is very short at higher frequencies generally used in direct-acting, high-caliber selection of Pilot. Product features: small pilot diaphragm structure coil power consumption, long life should work long hours for general pressure systems, the use of media: water, air, oil, natural gas, hot water.
