Quick exhaust valve

from Wikipedia, the free encyclopedia

Quick exhaust valves are used to increase the piston speed of pistons in pneumatic cylinders .

The quick exhaust valve is usually a valve with a non-return function in the inlet line of the pneumatic cylinder, which is combined with a ventilation function for venting the pneumatic cylinder directly to the outside.

In the case of single-acting cylinders, the inlet and outlet lines coincide, while they are separate in the case of double-acting cylinders. In the first case, the quick exhaust valve is to be placed in the only existing pressure line to the cylinder; with double-acting cylinders, this is placed in the input line. Long return times, especially with single-acting cylinders, are shortened as a result. In order to reduce air resistance , it is most practical to build the quick exhaust valve directly adjacent to or as close as possible to the cylinder.
