BS Soft Sealing Gate Valve – China Manufacturer & Supplier

Premium Quality BS Soft Sealing Gate Valves from China

As a professional China BS soft sealing gate valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance resilient seated gate valves that fully comply with British Standards. Our BS soft sealing gate valves—also known as resilient seated gate valves or rubber sealed gate valves—are engineered to provide bubble-tight zero leakage isolation in water supply, wastewater treatment, fire protection, and industrial pipeline systems.

A soft sealing gate valve employs a rubber-encapsulated wedge that forms a resilient seal against the valve body when closed. Unlike traditional metal-seated gate valves, soft sealing gate valves achieve zero leakage (Rate A – Bubble Tight) by utilizing the elastic memory of EPDM rubber to maintain a perfect seal even after repeated operations. This design eliminates the common problems of leakage and rusting found in conventional gate valves while offering low operating torque and long service life.

Superior Design Features

Our BS soft sealing gate valves incorporate several advanced design features that deliver superior performance and reliability:

• Rubber-Encapsulated Wedge – The wedge is fully vulcanized with EPDM rubber, ensuring that no iron is exposed to the medium, preventing corrosion and guaranteeing a perfect seal.

• Full Bore Design – 100% port diameter matches the pipeline, ensuring minimal pressure drop and smooth flow characteristics.

• Non-Rising Stem (NRS) Configuration – Ideal for space-constrained installations such as underground chambers and buried service.

• Low Operating Torque – Wedge guides made of wear-resistant POM material minimize attrition and ensure smooth, uniform closure.

• Triple O-Ring Stem Sealing – Three EPDM O-rings plus a dust seal provide reliable stem sealing under pressure, ensuring long-term leak-free operation.

• Fusion-Bonded Epoxy Coating – Internal and external epoxy powder coating (min. 250μm) provides excellent corrosion protection, with GSK certification available for potable water applications.

Applications & Industries

BS soft sealing gate valves are indispensable across multiple sectors:

• Water Supply & Distribution – Potable water networks, pumping stations, distribution mains

• Wastewater & Sewage – Treatment plants, force mains, sewer systems

• Fire Protection Systems – Fire main isolation, sprinkler systems

• Irrigation Systems – Agricultural and landscape irrigation networks

• Industrial Pipelines – Neutral liquids, cooling water, HVAC systems

• Buried Service – Underground installations with extension spindles
