VBQF-D-G18-E quick exhaust valve 547533. Flat screw-in exhaust air control with reduced noise emission. Basically, this functions like a non-return valve where the air escapes laterally to atmosphere in the closed position.
Product Description
Quick exhaust valve VBQF-D-G18-E Valve function=Quick exhaust, Pneumatic connection, port 1=G1/8, Pneumatic connection, port 2=G1/8, Mounting type=Threaded, Standard nominal flow rate, exhaust=850 l/min
Quick exhaust valves
With many applications, it is important to obtain the highest possible speeds in order to assume the start position for a working cycle.
In such cases here it is often a disadvantage that the air escaping from the cylinder has to travel the “long and narrow” way through the exhaust duct, a one-way flow control valve, the directional control valve and a silencer. This costs time and as such speed, since a cylinder can only be filled with air on the one piston side according to the corresponding air volume being evacuated on the other piston side.
In such cases a type of “short-cut” is used to vent the cylinder, i.e. the quick exhaust valve. Basically, this functions like a non-return valve where the air escapes laterally to atmosphere in the closed position.
Check valves and quick exhaust valves
Check valves and quick exhaust valves combine the function of flow control and stop valves in one component. The compressed air can flow freely in one direction, while in the opposite direction the flow rate can be changed by an adjusting element. Check valves and quick exhaust valves are often used with pneumatic cylinders to regulate speed. A stop valve that has been very successful in pneumatics and is therefore part of our Core Range is the HGL with a piloted non-return function. The HGL has an external thread so it can be screwed in, it is pneumatically piloted and is compatible with M5, G1/8…G1/2 connections as well as fittings QS-4…QS-12. The stop valves H, HA and HB with non-return function can be used for a wide range of applications thanks to the connecting threads and plug-in connection on both sides. The piloted check valve VBNF has a low overall height, can be rotated 360° horizontally when mounted and allows a high flow rate. The valves SE, SEU and VBQF are suitable for quick exhausting. The latter stands out thanks to its low installation height, high flow rate and reduced noise emission.
