PERFORMANCE ADVANGATE

1.Side flange complies with GB,DIN,GOST,ASME,BS, JIS standard.

2.GGG40 valve body material, level 3 spheroidizationl rate. Stronger mechanical properties, 

tensile strength 450Mpa, elongation more than 10%. Compared withl gray iron body, tensile strength

of the same thickness is twice that of gray iron body. The applicable working pressure is higher.

3.Akzo Nobel epoxy coating. Spray thickness up to 250 m. Strong adhesion.

4.lmport EPDM rubbermaterial. 50% rubber content. Stable and small torque,zero leakage after open 

and close more than 10000 times.
