British Standard BS5163 Soft Sealed Gate Valve
For a long time, the common gate valves used in the market are generally leaking and easy to rust. The soft-sealed gate valves produced by our factory with advanced foreign technology are widely used. It overcomes the defects of poor sealing, elastic fatigue and rust prone of general gate valves. Soft-sealed gate valve is a replacement product of traditional gate valve. It uses elastic gate plate to compensate micro-deformation and achieves good sealing effect. It has the advantages of light switch, reliable sealing, good elastic memory and long service life. It can be widely used in tap water, sewage, construction, food, power, medicine, metallurgy, textile, energy system and other fluid pipelines. It is used as a regulating and closing device.
