KELOR Rising Stem Resilient Seat Gate Valve is a robust isolation valve designed for on-off service where tight shut-off, durability, and ease of maintenance are critical. Manufactured using precision engineering and high-quality raw materials, this valve complies with international standards and is widely used across municipal, industrial, and utility-grade applications.
The rising stem design allows the stem to move upward as the valve opens, providing a clear visual indication of valve position. This feature is particularly beneficial in underground installations, pumping stations, and fire protection networks where operational status must be identified instantly. The valve incorporates a resilient elastomer-lined wedge that ensures bubble-tight shut-off, even after prolonged operation.
KELOR resilient seat gate valves are available in flanged end connections suitable for ANSI, DIN, BS, and IS standards. The epoxy-coated ductile iron body provides excellent corrosion resistance, making the valve ideal for potable water, raw water, treated effluents, and neutral industrial fluids.
Designed for low head loss and bi-directional flow, the valve operates smoothly with minimal torque. The stainless steel stem and precision-machined stem nut ensure reliable operation and reduced wear. Each valve undergoes stringent quality checks including hydrostatic and seat leakage testing before dispatch.
As a trusted Indian manufacturer and exporter, KELOR supplies rising stem resilient seat gate valves for bulk projects, OEM requirements, and international tenders. Our valves are widely used in water distribution networks, fire fighting systems, irrigation pipelines, desalination plants, and infrastructure projects.
