How To Choose The Steam Solenoid Valve Correctly?
The steam solenoid valve is divided into two types: boiler steam-saturated steam and steam from thermal power plants-superheated steam. Steam solenoid valves are widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments, as well as automatic control systems such as bathrooms, canteens, and air conditioning.
Boiler steam saturated steam
The temperature and pressure are relatively stable, the temperature is lower than 250℃, and the working pressure is lower than 1.6Mp. Usually use soft-seal steam solenoid valves as follows:
Structural features: The steam solenoid valve is a pilot-operated double-opening stainless steel solenoid valve composed of two major components: the auxiliary valve and the main valve.
Heat resistance: special high temperature resistant electrical materials and sealing materials are used for electromagnetic parts and sealing parts, and various heat insulation measures are applied.
Wear resistance: reasonable selection of materials, the valve cup and guide sleeve cleverly use the lubricating effect of fluid to reduce wear and increase life.
Condensation resistance: The condensate of the steam pipe is an important factor affecting the action of the steam solenoid valve, and is not affected by the condensate.
Other uses-soft seal
The selection of the steam solenoid valve ensures the stable operation of the solenoid valve under high temperature conditions. It is widely used in textiles, printing, chemicals, plastics, rubber, pharmaceuticals, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments, as well as bathrooms and canteens. , Air conditioning and other automatic control systems
