Dixon Valve SCVM10 Brass Safety Check Valve 1-1/4" NPT Male x 1-1/4" Hose ID Barbed - 300-340 SCFM Flow Rate for Water, Air, and Gas Applications - Ideal for Industrial, Plumbing, and HVAC Systems

Dixon Valve Air Fitting safety check valve. Application: conforms to OSHA regulation 1926.302 (b) (7) requiring a safety device at the source of the air supply and at branch air lines. Applications include temporary plant/factory air, construction sites, shipyards or utilities. Not for use in applications where 100 percent of the available air is required, I.e. Sand blast, pile driving rigs, expansion joint blow down pipes, etc. Does not prevent backflow. Construction: solid brass body and valve. Stainless steel spring and roll pin. Maximum working pressure: 250 psi. Maximum temperature: 250 degrees F. Use: safety check valves operate by using the pressure differential across the valve to operate the valve and spring assembly. The pressure differential is directly related to the flow of air (scfm) through the valve.

High flow valve to provide optimum performance

Controls excess air flow (SCFM) in only one direction

Automatically senses change in air flow and shuts off the flow in the event of a surge in excess of valve flow rating thus preventing hose whip
