1. Features:
1. The one-way valve is a valve that controls the air flow to flow in only one direction, but not in the reverse direction.
2. The combination of the valve and the throttle valve can control the movement speed of the cylinder and prevent the air from flowing back in the circuit.
3. In the forward flow, the flow resistance of the valve is small, that is, the flow capacity is large; in the reverse flow, the sealing performance is good, that is, the leakage is small. Under the premise of ensuring sealing and overcoming friction, the opening pressure is relatively small.
