Connect a non-return valve at the entrance of the solenoid valve, there is an arrow on the non-return valve.

Solenoid valve P is the air inlet, A is the air outlet, B is the air outlet, block B, R and S are the exhaust.

Quick exhaust valve, P is the air inlet, A is the air outlet, R is the exhaust.

The slow valve opening speed is related to the elasticity of the hose and the exhaust speed in the valve cavity. A quick exhaust valve can be selected to increase the valve opening speed.
