The 1-1/2' Pneumatically Operated Y Type Control NC (Normally Closed) Screwed Valve is a high-performance industrial valve designed for accurate flow control of steam, air, water, gases, chemicals, oils, and other process fluids. The Y-pattern body design ensures smooth flow with minimal pressure loss, making it ideal for demanding industrial applications. This valve remains in the closed position when no air pressure is applied and opens automatically when pneumatic pressure is supplied to the actuator. Its screwed-end connection allows quick installation and easy maintenance in various piping systems.
