Home Forums General Discussion Technical Questions GMV 3010 EN 1 1/4" valve problem

Looking for some help on a residential job that I got dispatched to. It's a Residential Elevator Inc. unit. Allen Bradley controller and a GMV power unit. Sent the car up to do a preliminary releif valve pressure test with the M/R valve before going up to the stop ring. I had 250 psi no-load pressure on the way up, closed the valve and the pressure just slowly went down to 200 psi and the car stalled. There is an 1/8" stream of oil shooting out of a short threaded nipple on the bottom side of the valve. Did I lose a cap off of that nipple? I can't seem to find a drawing of the bottom side of the 3010 valve.
