Suitable for use with drinking water , west water and liquids chemistry medium pipeline and appliance , can throw and shut flow .
 Ductile iron GGG40 body , bonnet and Wedge Disc for high physical performance and high strength , improve its working pressure and increase its useful life.
The ductile iron disc framework is thermal-clad integrally with high-performance rubber , ensuring a high elasticity , long service life and tight-sealing .

The cast is sprayed with epoxy resin coat both inside and outside , so without corrosion and water rust appearing , effectively preventing second pollution , It is a no-pollution environment protection product in 21 century .
Stainless steel spindle and gunmetal components for corrosion resistance , increase its useful life and achieve the lowest seal torque .

 

                                                                                                                                                

 

 

The sealing surface of the body is flat without hollow , so that ensuring small flow block , no leakage and damage made from any dirt deposit .
 Maximum temperature below 120C ,applicable for food , medicine , heat supply pipeline etc. cryogenic liquid project .
Don t  disassemble the valve form operation pipeline when maintained , can get quick maintenance on-line .
