3/4" FNPT x FNPT Stainless Steel Spring Check Valve
The 3/4" FNPT x 3/4" FNPT Stainless Steel Check Valve (VCV-WOG1000-F075) is a high-quality, 3/4" vertical spring-loaded check valve engineered for reliable fluid control. This valve is designed to prevent backflow in piping systems by utilizing a spring system that shuts the disc closed when there isn't sufficient upstream pressure to hold it open. It also closes when fluid pressure moves in the backward direction, ensuring unidirectional flow.
Constructed entirely from 304 stainless steel for the body, spring, and disc, and featuring PTFE (Teflon) seals and seal rings, this valve offers exceptional corrosion resistance. This makes it suitable for a wide variety of fluids, including water, oil, gas, air, light alkalis, acids, biodiesel, fuels, and alcohols. It is rated for a nominal working pressure of 1000 PSI (WOG1000) and can withstand a maximum working temperature range of -20°F to 302°F (-29°C to 150°C).
The P-WAT-3215 is a 2-piece serviceable design, allowing it to be opened by unthreading at one of the port ends for maintenance. It features 3/4" Female NPT (FNPT) connections on both ends for easy inline installation. While check valves do not create a 100% seal like a ball valve, this valve provides effective backflow prevention. For applications requiring absolute backflow prevention, using two check valves in series is recommended. The valve's approximate dimensions are 70mm (2.8") in length and weighs 0.66 lb.
