The non rising stem gate valve, the whole body of strobe is treating with rubber to redeemdistortion, and reaching the good seal finally. To conquer the phenomenon such as badnessseal, slack , rustiness and soon. Saved the fixing space effectively. This valve widely applied in theliquid pipes for opening or closing fixing in such water, sewage disposal, electric power, energeticspipe , chemical, shipping, energy sources etc.
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.
Three "O" 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.
Light weight
This body is made of ductile iron, it is 20%-30% lighter than the olds. Easily to fixing and servicing.
