Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic component used to control fluid. It belongs to actuator. Pneumatic solenoid valve is one of them. It blocks or leaks different oil drain holes by controlling the movement of valve body. The oil inlet hole is normally open, and hydraulic oil will enter different oil drain pipes, Then the oil pressure of the pneumatic solenoid valve pushes the piston of the oil cylinder. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.

It can work normally under vacuum, negative pressure and zero pressure, but its diameter is generally less than 25 mm.
It can also operate under zero pressure difference, vacuum and high pressure, but it has high power and must be installed horizontally.
The upper limit of fluid pressure range is high, which can be installed arbitrarily (need to be customized), but the condition of fluid pressure difference must be met.

There is a closed cavity in the pneumatic solenoid valve, and there are through holes in different positions. Each hole of the pneumatic solenoid valve leads to different gas pipes. There is a valve in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified;
The pneumatic solenoid valve blocks or leaks different exhaust holes by controlling the movement of the valve body, and the air inlet is normally open. High pressure gas will enter different exhaust pipes, and then push the piston of the cylinder through the air pressure of the pneumatic solenoid valve. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Operation principle of pneumatic solenoid valve
We said the pneumatic solenoid valve working position (solenoid valve on or off), in fact, refers to the pneumatic solenoid valve spool position.
Multi-function control valve application principle
The valve is based on the medium pressure of the pipeline itself as a power source for opening and closing and adjusting. Different combinations of the pilot valve and the system small pipe can have nearly 30 kinds of functions and are gradually being used more commonly. ? Pilot valve by the control object as the water level and pressure changes and action, as a large number of pilot valve can be used alone or in combination, you can get the main valve on the water level and pressure and flow, etc., separately or in combination Function But the main valve is similar to the globe valve, the valve is fully open, the pressure loss is much larger than other valves, and each opening loss coefficient is more close with the full closure, the more drastic increase in valve diameter is more significant. Valve with the above characteristics, near full closure, the valve action is accelerated, prone to water hammer (water impact pressure), close to fully closed, the slower the valve action as possible, so you can set the valve flap Flow institutions. In addition, the pilot valve throttling and the action part should try to avoid setting a special small aperture to avoid clogging. If necessary, add filters, regular maintenance and set up by-pass pipeline. This valve development, the use of promising.
