Metal Seated Gate Valve Specifications:

Metal Seated Gate Valve FEATURES 

⊙ 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. 

⊙ Rigid round body 

The body is founded minutely, the rigid geometry size ensure inner sealing of valve without 

any process. 

⊙ Light weight 

This body is made of ductile iron, it is 20%-30% lighter than the olds. Easily to fixing and 

servicing.
