1. Thrust bearings to reduce operating torque.
2. Three O-ring can significantly slow down the phenomenon of water leakage, and in the case of pressure and constant water to replace the O-ring.
3. Precision machining valve rod, can reduce operating torque
4. Internal and external usd of rubber fully coated, connect firmly, can avoid fall of while long-term use.
5. No dent at the bottom of valve body, is not easy to cause debris accumulation.
6. In the body, the use of non-toxic powder epoxy resin coating, strengthening anti-corrosion ability, improve the quality of water.
