Carbon steel flange butterfly valve with wrom gear operation
JRVAL specialized in carbon steel material flange type butterfly valve production, which have been focusing on carbon steel material flange butterfly valve production over 15 years, with hundreds of buyers from domestic and overseas market.
 
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, expanded 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.
