4.3, high reliability

     From the weight of the breakthrough features were not enough, the reliability of valves must also be greatly improved, super-light full-featured solution to the main wall valve:

     1) the reliability of sealing stem --- great stiffness and wear-resistant stem packing, PTFE packing life is 2 ~ 3 times;

     2) batteries, the reliability of Block --- sealed batteries, sealed hard seat, and wear-resistant surfacing alloys used for further protection, such as their life expectancy is PTFE soft seat, stainless steel brass ball valve seat unparalleled;

     3) electric valve with high reliability of the electronic implementation of institutions --- 5 ~ 10 years maintenance-free, a better solution to the electric actuator poor reliability issues;
