westwind pressurization

 

 

 

 

 

 

The valve opens correctly with shop air applied, and the controller  disconnected, and slight vacuum applied to control circuit

 

 

 

 

Front valve will open when control i connected straight to the pneumatic relay.

 

 

 

Ground prepress seems to work correctly

 

 

 

 

Aircraft pressurizes hard on the ground, straight to 3 psi at idle.  Fwd valve will not open via the controller.

 

Turns out the limit valve was failed.  It had opened because the pilots got the cabin to 17,000 feet.  Then the brass seat fell out of place.  Then valve leaked from then on .
