First, be sure you've got the right part specified. I know a lot of people who frequently mistake the purge valve for the air governor. In either case, replace it... the air governor is a $20 part. If that doesn't do it, check for leaks from the valves in the firewall, because a faulty MV3 valve is a definite possibility.
QR-1C valve takes air from the PP-1 or MV3 valve. That air goes through a line to the inlet of the QR-1C valve. As it does, it pushes down a diaphragm, which covers the exhaust port. Thus, the air is piped out of the outlet ports to the spring brake side of the brake chamber. When the air supply is removed, the diaphragm returns to an open state. This opens the exhaust port, and air from the spring brake chamber is evacuated out through it. If it's leaking air, if your brakes aren't releasing, if your brakes aren't setting when you pull the yellow brake control valve, or you get air exhausting steadily through the treadle valve with the brake control valve pressed, an issue exists.
Valve pocketing is when a valve is hammering the valve seat.mostly due to miss adjusted valve spring/wrong valve spring/to strong of a valve spring or valve stem to short.Makes the valve seat deeper.
tricuspid valve,bicuspid valve and pulmonary valve
A valve spring "keeper" or AKA a valve spring "retainer" is used to lock a valve spring to the valve.
# The PCV valve is located in the valve cover # Detach the hose from the valve then unscrew the valve from the valve cover
Spill valve is a overflow valve.
Ileocecal valve
The valve guide is a precise hole in the head that the valve stem slides in. The valve is retained by the retainer and two valve locks.
