Solenoid Valve Description

1) : Rexroth solenoid valve and all stainless steel; For strong corrosive media must be selected isolation diaphragm type. Neutral medium, it is also appropriate to choose copper alloy as the valve shell material of the solenoid valve, otherwise, the valve shell often has rust chips off, especially in the case of infrequent action. Ammonia valves can not be made of copper.

2) : Explosive environment: the corresponding explosion-proof grade products must be selected, and waterproof and dust-proof varieties should be selected for outdoor installation or dust occasions.

3) : The nominal pressure of the solenoid valve should exceed the maximum working pressure in the tube.

Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm.

Distributed direct acting solenoid valve

Principle: It is a combination of direct action and pilot principle, when there is no pressure difference between the inlet and the outlet, after the power is turned on, the electromagnetic force directly puts the pilot small valve

And the main valve closing parts are lifted upward in turn, and the valve is opened. When the inlet and outlet reach the starting pressure difference, after power, the electromagnetic force pilot small valve, the main valve

The pressure of the lower chamber rises and the pressure of the upper chamber decreases, so that the main valve is pushed upward by the pressure difference. When power is off, the pilot valve is pushed by spring force or medium pressure

Move the closing piece and move down to close the valve.

Features: It can also be operated at zero pressure difference or vacuum and high pressure, but the power is large, and it must be installed horizontally.

Pilot operated solenoid valve

Principle: When energized, the electromagnetic force opens the pilot hole, the pressure of the upper chamber drops rapidly, forming a low and high pressure difference around the closing part, and the fluid pressure

The force pushes the closing part upward to move, and the valve opens; When the power is off, the spring force closes the pilot hole, and the inlet pressure forms a low and high pressure difference around the valve closing part through the bypass hole rapidly, and the fluid pressure pushes the closing part to move down and close the valve.
