Shut-off valves allow the controlled opening and closing of piping and thus the compressed air supply in pneumatics. At Festo you will find on/off valves, ball valves and logic valves for pneumatic applications alongside check valves and quick exhaust valves.
Check and quick exhaust valves combine the function of flow and check valves in one component. The compressed air has free passage in one flow direction, while in the opposite direction the volume flow can be changed by an adjustment element. In conjunction with pneumatic cylinders, check and quick exhaust valves are often used to regulate speed. A shut-off valve that has proven itself in pneumatics and can therefore be found in our core range is HGL with a pilot-operated non-return function. HGL can be screwed in with an external thread, can be released pneumatically and is compatible with the connections M5, G1/8...G1/2 and QS-4...QS-12. The shut-off valves H, HA and HB with non-return function can be used in a variety of ways thanks to the connection threads and plug-in connections on both sides. The delockable check valve VBNF has a low overall height, can be rotated horizontally by 360° when installed and enables a high flow rate. The SE, SEU and VBQF valves are suitable for quick exhausting. The latter scores with its low overall height, high flow rate and reduced noise emissions.
