Tips:
The pneumatic hand lever valves usually go on reversing through the outer forces. When the outer strength disappears, the valve will come back to the original position and exchange the direction. The structure soloker knob and emergency push button with lock has the memory function. However, according to the function of valves, it's divided into three way and two position as well as 5 way 2 position. The 3/2 way usual is used to control the output signal of pneumatic system and the 5/2 way can directly drive the cylinder.
Pneumatic hand lever valve, three way, two position, with 1/4, 3/8, 1/2 inch port, provide a manual return operation to allow the air to pass. This air valve can be used to control air chucks, pneumatic actuators and venturi vacuum generators.
