Suction Valves

(Hot Gas, Suction-Throttle, POA & VIR)

What is a suction valve?

The suction valve is found on most 60’s and 70’s GM vehicles. There are several different types, generally varying by model year as follows:

The first three are all different kinds of suction valves. They are mounted to the evaporator’s suction (top) outlet and regulate system pressures so as to prevent the evaporator from freezing up.

The Valve-In-Receiver is a POA valve, drier, and expansion valve all in one. It too is mounted on the Evaporator.

Due to market changes, we have made the hard decision to no longer offer restoration services. We do offer replacement upgrade kits and bolt in aftermarket kits to cover the void.
