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) Based on different valve size and differnet opening torque, worm gear includes small torque, medium torque, large torque, single gear, double gear, tripple-gear etc;
5) With Different settings can be customerized, such as: Worm gear+signal, worm gear+indicator, worm gear+solenoid, worm gear+bracket, worm gear+ Siemens electric controller, worm gear+ indicator light and other configurations are avialable.
