Chemical GGG40 Non Rising Stem Ductile Iron Gate Valve

Non Rising Stem Ductile Iron Gate Valve

Ductile Iron Gate Valve FEATURES

⊙ Flatting seat

Smooth continuous bore way without seating recess, it is not easy to get impurity pilled up.

Making the liquid straightway.

⊙ Treating with rubber

Both inner and outer are coated with advanced knowledge of rubber vulcanization then making

sure of the elasticity of rubber ,and make sure the exact geometry dimension. Rubber and ductile

cast iron valve hand together hardly. This can avoid fall-off due to long-term use.

⊙ Anti- corrosion

Both inner and outer are coated with non-toxic powder epoxy resin to strengthen the capacity of Corrosion resisting and raise the quality

of water supply.

⊙ Ruggedization

The older ductile iron valve is easy to rupture after being impacted by nonego. It can stop

rupture depend on the good mechanics capability of ductile iron .

⊙ Three “○” sealed ring

With the three “O” – rings, the leakage can be greatly reduced and the “O” – ring can be

replaced under this condition with pressure and without stopping water. The thrust axletree

reduces the frictional resistance and lowers the operational torque. And it can be switch seal

ring without opening and closing.

Ductile Iron Gate Valve Applications :

This valve widely applied in the liquid pipes for opening or closing fixing in such

water, sewage disposal, electric power, energetics pipe , chemical, shipping, energy sources etc.
