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.
