How to choose the correct introduction of steam solenoid valve

The steam solenoid valve is an automatic basic component used to control the direction of the fluid. It is an actuator; it is usually used for mechanical control and industrial valves. It controls the direction of the medium to achieve the control of the valve.
There are closed chambers in the steam solenoid valve. There are through holes in different positions. Each hole leads to different oil pipes. The middle of the cavity is a valve. On both sides are two electromagnets. Which side of the magnet coil is energized? Which side is attracted to, by controlling the movement of the valve body to block or leak different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then pushed by the pressure of the oil The piston of the cylinder, which in turn drives the piston rod, and the piston rod drives the mechanical device to move. This controls the mechanical motion by controlling the current through and off of the electromagnet.

The high-pressure solenoid valves currently in use are usually the following two types of steam:
1. Boiler steam-saturated steam temperature is relatively stable, the temperature is lower than 250 °C, and the working pressure is lower than 1.6Mp. Shanghai Nuoyou Valve Industry usually chooses the soft-sealed steam solenoid valve as follows:
Structural features: This valve is a pilot-operated double-opening stainless steel solenoid valve consisting of two major components, the secondary valve and the main valve.
Heat resistance: Special parts of high temperature resistant electrical materials and sealing materials for electromagnetic parts and seal parts, and various insulation measures are applied.
Wear-resistance: Reasonable material selection, the valve cup and the guide sleeve skillfully use the lubrication of the fluid to reduce wear and improve life.
Resistance to condensation: The condensate of the steam line is an important factor affecting the operation of the steam solenoid valve. The valve is not affected by the condensed water.
Other uses - soft seal
This series of solenoid valves can also be widely used in textile, printing, chemical, plastics, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments as well as bathroom, canteen, air conditioning and other automatic control systems.

2. The steam-superheated steam temperature change from the thermal power plant has a large base, the temperature is up to 400, and the working pressure is lower than 4.0Mpa. Hard-sealed steam solenoid valves are usually used as follows:
Structural features: The use of metal hard seals improves the service temperature and service life of the product.
The material selection is reasonable, and the valve cup and the guide sleeve skillfully utilize the lubrication of the fluid to reduce wear.

Steam Solenoid Valves Other Applications - Hard Sealed Low Temperature Solenoid Valves This product has a wide range of general purpose media and can be used in water, light oil, heavy oil, non-corrosive gases and steam. For example, in the exhaust system of the suction pipe of the power station and the exhaust system of the evaporator, the two-position automatic adjustment and remote control are mainly performed on the medium in the pipeline.
