National Standard Soft Sealed Gate Valve
National standard soft sealing gate valves can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, power, ship, metallurgy, energy system and other fluid pipelines as regulating and closing devices. Our factory introduced the European high-tech valve manufacturing technology to produce elastic seat gate valves, using the integral glue encapsulation of the gate to produce deformation compensation effect, achieved good sealing effect, overcome one. The phenomenon of poor sealing, leakage and rusting of general gate valves. It can be widely used in water, sewage, construction, petroleum, chemical industry, food, medicine, light injury, electric power, ship, metallurgy, energy system and other fluid pipelines as regulating and closing devices.
