non-Return C Non-Return Valves General Information Parker offers two styles of Non-Return valves, In-Line, tube to tube, and a threaded version with NPT male threads. Their extreme compactness and light weight make them suitable as a safety item in compressed air circuits. The body of the fitting is marked with an arrow to indicate the direction of flow. General Principle Parker Non-Return Valves allow air to pass in one direction while blocking flow in the other direction. A pressure of more than 7 psi will overcome the spring pressure, which is keeping the valve closed, thus allowing the passage of air. Valve Specifications Maximum Working Pressure: 145 PSI Operating Temperature: +30� to +160� F Body Material: Nylon / Nickel-Plated Brass Body Parker Hannifin Corporation C31 Parker Brass Products Division Otsego, Michigan non-Return
