Non-Rising Stem (NRS) valves, also known as rotary stem or blind stem wedge gate valves, feature a stem that rotates to open and close the gate without moving up or down. As the stem turns, it moves into or out of the valve, which in turn moves the gate to control flow. These flanged NRS valves are widely used in hot and cold water systems, HVAC, steam, gas, and general utility services. We offer a complete range of flanged non-rising stem gate valves in sizes from 2? to 16?, with options for solid wedge and bolted bonnet designs. OEM customization is available for specialized needs or large orders, ensuring tailored solutions for various industries.
