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 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. 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. G 1/4" to G 3/4" Quick Exhaust Valves are used to increase the cylinder piston speed by around 2 times. These Flow control valves allow free flow in one direction & controlled flow in the other so as to regulated the speed of cylinder. G 1/8" to G 1/2" Banjo Flow Control Valves for direct mounting on cylinder port. G 1/8" to G 3/4" Inline Flow Control Valves for line or panel mounting. Both the above version available with knob type & recess type design.
