Pneumatic Quick Exhaust Valve

03/23/2009 12:39 AM

I have a linear pneumatic cylinder (2000mm stroke, 63mm dia). The purpose is to lift a hinged flap upto 90 deg. (Max. reaction load on the cylinder will be 40Kg.) Then the flap should freely fall.I have to simulate this free fall using the pneumatic cylinder.

I have to select a quick exhaust valve for this purpose. Will this serve my purpose?

Frictional forces of the swab of the cylinder to the cylinder walls may prevent any approximation of free fall. A smaller bore cylinder would help. At 40 kg max load its over sized. Port size should be increased. The quick exhaust valve will serve its purpose needs to be mounted as close to the cylinder port as possible.
