Non Rising Stem Resilient Seat 2" inch gate valve manufacturer
I. BRIEF INTRODUCTION:
The non rising stem gate valve, the whole body of strobe is treated with rubber up to good seal conquering bad seal, slack, rustiness and so on and saving installation space effectively. This valve widely applied in the liquid pipes for open or close fixed in such water, sewage disposal, electric power, energetics pipe, chemical, shipping, energy sources etc.
II. 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 to the elasticity of rubber, and making sure the exact geometry dimension. Rubber and ductile cast iron valve are together hardly. This can avoid fall-off for 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 “.” – 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. Easy to fix and serve.
