Product Description
Parker PL37 Valve
These are 4-Way, 3-Position, rotary disc, direct-operated air valves. Two different types of control are offered. The forged bronze disc and the cast iron surface upon which the disc works are ground and lapped to provide a leak-proof seal. Air pressure from the inlet port is confined beneath the disc, making the seal tighter as the pressure increases, yet friction between the lapped surfaces is so low that only 15 pounds of force is required to move the lever at 100 PSI line pressure. The need for packing to seal around the stem is eliminated. Valve can be furnished for gasketing to a manifold on customer’s machine or with an adaptor for tapped bottom porting. Valves are detented. Operating handles may be installed in any of four positions
