Description
The Mosmatic 90.116 Check Valve is engineered for precision and durability in demanding water and fluid handling systems. Made of corrosion-resistant stainless steel, this valve is designed for systems requiring low opening pressure and robust performance. It features a ¼” NPTF IN thread and a …œ” NPTF OUT thread, allowing versatile integration into diverse configurations.
With a 1″ diameter and extended 2.2″ length, this valve is optimized for high flow capacity and low-resistance activation. It operates at an opening pressure of just 1.5 PSI and closes at 2 PSI€”ideal for sensitive systems where minimal pressure drop is critical. Rated for up to 4000 PSI and 200°F, the Mosmatic 90.116 delivers secure and efficient one-way flow control in both commercial and industrial environments.
