Steam solenoid valve

　　Solenoid valves specially designed for saturated steam and hot water to cope with the corrosiveness and temperature of hot steam. There are two common types of Steam Solenoid Valve, namely, direct-acting on most miniature solenoid valves, with small 1/8", 1/4", 3/8", or 1/2" threaded ports or pressure-assist (also called For pressure-assist). Servo or floating piston) solenoid valve, usually from 1/2", 3/4", 1", 11/4", 11/2" and 2" BSP or NPT thread or even flanged PN16, ANSI150Lb or Find the sizes DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250 and DN300 in the JIS10K port.

　　Steam Solenoid Valve is usually normally closed (power on), so the fault protection position is closed, there is an option of normally closed (power off) fault protection switch, but for health and safety reasons, avoiding the use of these solenoid valves is indeed Sensible. Without power, the valve will remain open.

　　Steam solenoid valve materials and Water Rotameter for construction and industry.

　　Steam Solenoid Valve has a variety of materials, including brass, bronze, stainless steel, and cast iron, which can be used according to the application and environment. Stainless steel solenoid valves are commonly used in food industry applications because brass or bronze are commonly used in industrial systems such as steam boiler outlets, commercial steam washing machines, or steam compressors in laundry shops, vending coffee machines, sterilization systems, forming and high-pressure Sterilizer system.

　　The internal seal of the Steam Solenoid Valve should usually use PTFE, which can withstand steam temperatures up to 200 degrees Celsius, but in some cases, cheaper elastomer seals (such as EPDM) are used, but the temperature is limited to 150 degrees Celsius.

　　Electromagnetic coils will also be suitable for high-temperature applications, usually rated as H (180 C) or N (200C)

　　Useful tip: The best practice is to use a solenoid valve with a PTFE seal. The steam rated temperature is up to 200C, but for hot water, the maximum temperature of EPDM is about 150C.

　　There is a useful graph showing the steam temperature in relation to the pressure because they are directly related.
