Products featurers:

 

1) the valve stem bearing use "copper sleeve", which with good wear and corrosion resistance. Although cost is 50% higher than other materials,  prolong the service life by 60-70%;

2) Rubber seat contains over 50% rubber, with stable resilience and tension. Although the cost is 30% higher than that of similar products in the market, its service life can be extended by 1-2 years; valve seat option with PTFE, NBR, EPDM, FKM etc.

3) Material of worm gear includes gray iron, ductile iron, stainless steel, aluminum alloy, etc;

4) Electric actuator includes intelligent type and switch-on-off type. Compared with hydraulic and pneumatic actuators, the electric actuator has higher cost-performance, and the integrated design of the electric actuator is easier to program and control, the maintenance workload is reduced to the minimum;

5) Electric Actuator is easy to get power, signal transmission speed is fast, with longer transmission distance, easier for centralized control, with high sensitivity and accuracy, connection with the dynamic regulating instrument is convenient and simple installation;
