Replacement 31A1FV15-Z Air Compressor Valves Electromagnetic Valve
Electromagnetic valve (Electromagnetic valve) is an industrial equipment controlled by electromagnetic. It is an automation basic component used to control fluid. It belongs to actuator and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. The solenoid valve can cooperate with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed control valves, etc.
Solenoid valves can be used not only in pneumatic systems, but also in the same or similar applications in hydraulic and hydraulic systems, such as low-power, non-oil-supply small electromagnetic directional valves, seals do not need to be supplied with oil, but are discharged The gas will not pollute the environment and can be used in food, medicine, electronics and other industries.
Now, the combination of solenoid valve technology, control technology, computer technology, and electronic technology has been able to carry out a variety of complex controls. For example, solenoid valves can be applied in the field of intelligent control and wireless control technology. The solenoid valve can be controlled by electromagnetic, so it can interface with various electronic systems well, which is also one of the main reasons why it is widely used.
Solenoid valves are divided into three categories in principle:
Direct Acting Solenoid Valve
Principle: When energized, the solenoid generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, and the spring presses the closing member on the valve seat and the valve closes.
Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm.
Step-by-step direct-acting solenoid valve
Principle: It is a combination of direct action and pilot type. When there is no pressure difference between the inlet and the outlet, the electromagnetic force directly lifts the pilot small valve and the main valve closing member in turn, and the valve opens. When the inlet and outlet reach the starting pressure difference, after power on, the electromagnetic force pilots the small valve, the pressure in the lower chamber of the main valve rises, and the pressure in the upper chamber drops, so that the pressure difference pushes the main valve upward; when the power is off, the pilot valve uses a spring The force or medium pressure pushes the closing piece and moves downward to close the valve.
Features: It can be operated under zero pressure difference or vacuum and high pressure, but the power is large, and it must be installed horizontally.
Pilot solenoid valve
Principle: When energized, the electromagnetic force opens the pilot hole, the pressure in the upper chamber drops rapidly, and a high pressure difference is formed around the closing part. The fluid pressure pushes the closing part to move upward and the valve opens; when the power is off, the spring force controls the pilot The hole is closed, and the inlet pressure passes through the bypass hole to quickly form a lower and upper pressure difference around the valve closing member. The fluid pressure pushes the closing member to move downward and close the valve.
Features: The upper limit of the fluid pressure range is high, and it can be installed arbitrarily (customization required) but must meet the fluid pressure difference condition.
