A Quick Exhaust Valve provides a rapid exhaust of controlled air when it is placed directly on an air cylinder after the control valve. The seal inside the quick exhaust valve allows exhaust to dump out the exhaust port directly.

The Quick Exhaust value has multiple applications. It is usually installed at a rod or blind end of a pneumatic cylinder. Quick exhaust valve provides a retraction and quick extension of the equipment. These valves operate by increasing the speed of the pneumatic cylinder rod to expel the exhaust air.

The control valve is used to get the desired control on different parameters of the fluid. The main function of the pressure valve is to control the force of actuators. 

A Quick Exhaust Valve is ergonomic. It is used in each port of the cylinder. The main purpose of the exhaust valve is to increase the speed of the rod in both directions. In a pneumatic cylinder, a quick exhaust valve is used to increase the cycling speed.
