Kingston Hoist Control Valve

The Kingston Model 303 Hoist Control Valve is designed to operate various lifting devices utilizing compressed air (or oil) as a power source. The valve body is of heavy cast brass construction with internal components of precision machined brass bar stock, stainless steel springs, stainless steel inlet screen and Buna-N-Seals to provide long life with minimum maintenance. Positive air control is achieved by the cam action of the "dead man" style lever on the Kingston Model 303. These valves are widely used on automobile, truck hoists and spring loaded single acting cylinders. Each valve is individually tested after assembly.
Maximum operating pressure, 200 psi
The Model 302 and the Model 303 are essentially the same design. The Model 302 features the "locking" style lever. The Kingston Model 303 achieves positive lock by the cam action of the "dead man" style lever. Check local standards to verify which valve can be used in your area.
