BS 5163 NRS Resilient Seated Flange Gate Valve

Rubber soft-seated gate valve, also known as resilient seated gate valve, is manufactured in accordance with the design standard of BS5163 and belongs to the family of rising stem gate valves. The NRS gate valve is widely used in water treatment, petrochemical, power generation and other fields due to its advantages of zero leakage and low cost. The non-rising stem (NRS) flange gate valve ensures precise sealing between the gate and the valve body by vulcanizing high-quality rubber onto the gate, achieving zero leakage. It adopts high-strength ductile iron as the valve body material to ensure the product performance meets industrial requirements. As one of the most common types of valves, the iron gate valve is usually used when the fluid medium in the pipeline needs to be shut off, as it only has two states: fully closed or fully open.
