Non-Rising Stem Gate Valve

ALIS Valves offers Non-Rising Stem Gate Valves for industrial applications requiring reliable flow isolation and space-efficient installation. These valves use a threaded stem mechanism in which the stem rotates without moving vertically outside the valve body, while the internal gate moves up or down to open or close the flow passage. This design is particularly useful in installations with limited overhead clearance, as it does not require additional vertical space for stem movement. When fully open, the gate provides a relatively unobstructed flow path, helping support efficient fluid movement with low flow resistance under suitable operating conditions.

Non-Rising Stem Gate Valves are suitable for applications in water distribution networks, water treatment plants, industrial pipelines, fire protection systems and other compatible fluid handling installations. They are commonly selected where dependable on-off isolation and compact installation are important. Key selection factors include operating pressure, temperature, fluid characteristics, valve size, body and gate materials, stem and sealing arrangement, end connections and applicable industry standards. Selecting the appropriate Non-Rising Stem Gate Valve helps support reliable shut-off, efficient pipeline operation and dependable performance under the intended working conditions.
