These are some typical 2-way and 3-way normally open and closed low power solenoid valves that are intended for portable refrigerant recovery-recycling systems. Their inlet pressure ratings range up to 500 psi. They come equipped with 1/8" and 1/4" NPT pipe ports, 3/8" copper sweat tubing, or with provisions for manifold mounting. Spade terminals, lead wires, or conduit connections for standard AC or DC voltages are available. Orifice sizes range from 1/32" to 1/4". Also available are compact stainless steel, brass, and aluminum manifolds with up to eight inlet ports. Some models have built-in back pressure designs, to eliminate redundant check valves by stopping possible refrigerant leakage during servicing.
