Vacuum electromagnetic pneumatic valve is introduced

vacuum electromagnetic pneumatic valve is used to control the direction of flow automation components, belonging to the actuator; Above are normally used for mechanical control and industrial pneumatic valve, to control the direction of the medium, so as to achieve control of the pneumatic valve switch. Solenoid pneumatic valve has closed cavity, in a different location to open a hole, each hole leads to different tubing, cavity pneumatic valve is among, both sides are two electromagnets, which face the magnet coil electricity pneumatic valve will be attracted to which side, by controlling the movement of the pneumatic valve body to blocked or leakage of different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push the cylinder piston, piston drives the piston rod, piston rod drive mechanism. So that by controlling the electric current of the electromagnet to control the mechanical movement. Only solenoid pneumatic valve is applied to seal in the electric control pneumatic electric magnetic valve magnetic casing insulation core completion, there is no dynamic seal, so leakage blocking off easily. Electric pneumatic valve torque control is not easy, prone to leakage, even snap pneumatic valve stem head; Solenoid pneumatic valve structure is easy to control the internal leakage, until reduced to zero. So, solenoid pneumatic valve using a special security, especially suitable for corrosive, toxic, or high and low temperature medium. Solenoid pneumatic valve itself has simple structure, low price, compared to adjust the pneumatic valve and other kinds of actuators is easy to install and maintain. More significant is composed of automatic control system is much simpler, much lower prices. Because electromagnetic pneumatic valve is switch signal control, connection with industrial control computer is very convenient. In today's computers, prices plunged, advantages of pneumatic valve is more obvious.
