Valves And Fittings – A Short Guide For Material Selection
March 20, 2020Benefits Of Using Stainless Steel Valves
March 20, 2020Pneumatic industries require precision system components to achieve high performance in a very small time period. Speed as 
well as efficiency is important in these systems.
Certain valves and couplings are designed to help achieve this rapid action. Quick exhaust valves, or QEVs, remain one of the most popular components in pneumatic applications.
As quick exhaust valve suppliers, we recommend opting for stainless steel products. They offer high tolerance and can fit almost any system and industrial process.
At SealExcel, you are sure to find a perfect fit for your required pneumatic applications.
Design and construction of QEVs
The valve design allows you to increase the speed and shorten the cycle time of a cylinder used in pneumatic systems.
Its application depends on your actuation requirements.
Installing a QEV may result in either rapid retraction or rapid extension, when used at the blind or rod end of the cylinder. Pressure removal on the QEV’s input port results in backflow at its output port.
The stainless steel quick exhaust valve configuration allows direct mounting on the compressed air systems. Improving the cylinder rod displacement speed, QEVs shorten the time required to complete a cycle. High precision is ensured during the process.
Important features of SealExcel products
Here are the key features of our QEV design:
