FEATURES
Shot-blasting
protective surface finished by shot-blasting and the surface is smooth and neatness.
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&n
