Industrial water supply and drainage, proportion principle and classification of pneumatic valve

direction control pneumatic valve: proportional solenoid pneumatic valve replace the direction of general solenoid pneumatic valve pneumatic valve pneumatic proportional direction valve, the sliding shaft can not only empathy, and empathy can trip or in proportion to changes in a row, so connected between the oil outlet oil area can be continuous or changes in proportion, so the proportional directional control pneumatic valve can not only control the movement direction of the actuators, also can control its speed.
