Quick exhaust valves are installed at the rod or blind end of a pneumatic cylinder to provide a quick extension and retraction of the equipment.
Quick exhaust valves
Quick exhaust valves operate by increasing the speed of the pneumatic cylinder’s rod in order to expel the exhaust air at the port of the cylinder directly.
One quick exhaust valve is used in each port of the cylinder to ensure an increase in the speed of the rod in both directions.
The use of a quick exhaust valve in a pneumatic system helps to increase cycling speed, in turn, that ensures a much smaller valve to be effectively used for the process.
