What is the electric pneumatic valve operation principle of electric pneumatic valve have?

English name: electrically operated valve. Electric pneumatic valve, in a nutshell is to use the electric actuator, pneumatic control valve so as to realize the pneumatic valve is opened and closed. It can be divided into fluctuation two parts, the upper part for electric actuator, the lower part of pneumatic valve. Electric pneumatic valve is divided into two kinds, a kind of for quarter-turn electropneumatic valve: from the Angle of travel of the electric actuator using with Angle of pneumatic valve, pneumatic valve degree. the spin control pipe flow on and off; Another for straight travel electropneumatic valve: by straight travel electric actuator with straight travel used pneumatic valve, pneumatic valve plate up and down movement control pipe flow on and off. Usually on the high degree of automation equipment.
electropneumatic valve usually linked by electric actuators, and pneumatic valves, become electropneumatic valve after installation and debugging. Electropneumatic valve using electricity as the power to turn on the electric actuator drive pneumatic valve, pneumatic valve switch, adjust the action. So as to achieve medium switch or adjust the purpose of the pipes.
solenoid pneumatic valve is a kind of electric pneumatic valve; Is the use of the magnetic field generated by electromagnetic coil to pull the pneumatic valve core, and transform the on-off of the pneumatic valve, power coil, will depend on the pressure of the spring return pneumatic valve core.
