Product introduction: the valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation. Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc. and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction, petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids.

Characteristics:
1. the seal is designed with dustproof ring plus three " O" -seal ring, reliable sealing, on-line replaceable.
2. both gate and aluminum bronze bearing are in in aid design good self lubrication, high strength and can have the aluminum bronze bearing replaced without need to replace the gate integrally, after a long time use.
3. Rubber wrapped gate anti-corrosion, good tightness.
4. Advanced surface treatment, coated with non-toxic epoxy resign static powder, anti-corrosion, pollution-free, can be used drinking water pipeline.
5. the body is designed without gate slot, the smooth passage will not get impurities filling up, more applicable for sewage working condition.
6. the integral seal works raliably. for the high pressure seal, leaving zero leakage under1.5 times nominal pressure and,for the low pressure one,under 0.02Mpa.
