Description
Non Rising Stem Resilient Seated Gate Valve Manufacturer – KELOR
KELOR Non Rising Stem (NRS) Resilient Seated Gate Valve is engineered for dependable isolation service across municipal, industrial, and utility pipeline networks. Unlike rising stem designs, the non-rising stem mechanism keeps the stem position fixed, making it especially suitable for buried pipelines, valve chambers, and installations with limited vertical clearance.
The valve features a fully encapsulated resilient rubber wedge that ensures tight shut-off in both directions, even under low-pressure conditions. The smooth epoxy-coated body and wedge minimize head loss and protect against corrosion, making the valve ideal for potable water, raw water, irrigation, firefighting, and wastewater applications.
Manufactured in compliance with international standards such as EN 1171, EN 1074, and BS 5163, KELOR NRS Gate Valves are available with flanged ends suitable for ANSI, DIN, and BS flange drilling. Each valve undergoes stringent pressure and leakage testing to guarantee long-term, maintenance-free performance.
KELOR offers these valves in a wide size range with durable ductile iron construction, stainless steel stem, and replaceable elastomer seats. The non-rising stem design also allows easy operation using handwheel or gearbox without exposing the stem threads to external contaminants.
