Humphrey Products Co”s Super Quick Exhaust Valves are designed to outperform flat-disc-type diaphragms found in other valve designs. The valves feature a special molded shuttle designed specifically for quick service. The valve also solves a common lubrication problem when using small-bore cylinders — i.e., the small displacement of air per cycle results in poor lubrication. The unique design of the valves stops lubricant backflow through the control valve on the exhaust cycle, allowing progressive oil flow to the cylinder. The shuttle”s full-formed seating surface provides long cycle life, and the shuttle design eliminates the need for flow restricting metal body webbing. Valves are available in a range of port sizes from #10-32 to 3/4″. Operating speeds up to 600 CPM, with pressure range to 150 PSIG and working temperature range from -25 F to 180 F.
