A spring biased ball or optional poppet check provides full flow in one direction; a stainless steel, tapered needl provides a wide range of adjustment of flow in the controlled direction. A locknut prevents unwanted changes in adjustment. A tamperproof adjustment key is standard; a knurled knob is optional.

A wide range of flow adjustment is possible because of the fine thread, tapered needle. Unwanted changes in adjustment are prvented by a locknut. A tamperproof adjustent key is standard; knurled knob is optional.

A slight pressure differential fully opens or closes the ball or poppet check valve. This valve is available with either ball check or bubble-tight poppet check.

When standard valves can’t get your product where you want it to be, the Humphrey Engineered Solutions team can help. As a pioneer in the pneumatic industry, they can bring over half a century of in-depth knowledge, experience across multiple industries and countless innovations to your project. Each project starts with their engineers working directly with your engineers to determine your needs. Then they refine the concept and incorporate the right Humphrey valve or valve components to achieve your design objectives. The Engineered Solutions team will produce one or more designs, together with an analysis of the cost benefits and implications for future life cycle benefits. Utilizing proven standard Humphrey valve technology contributes to the highest possible performance—and product reliability.

Peter Paul Series 20,30 and 70 solenoid valves offer a wide range of control options over the flow of liquids and gases in applications from dispensing to instrumentation, commercial equipment, machinery, medical/dental equipment, control systems and off-highway equipment, to name just a few. These Series are available in 2 and 3 way construction, in brass, stainless steel and plastic bodies, depending on the model selected. The valves can be used to control a wide variety of oils, water, solvents, gases, process fluids and steam.

Super high pressure ratings with bubble tight sealing. Ratings up to 3000 psi.

Peter Paul’s miniature, low-cost, high performance solenoid valve line is particularly adaptable to original equipment manufacturers in their development of fluid power and fluid control equipment. The Series 50, 15, and 58 valves can be found in medical and dental instrumentation, analytical and HVAC equipment.
