Shanghai Kangquan Valve Co., Ltd.

Rising Stem Resilient Seat Gate Valve

BRIEF INTRODUCTION

Resilient-seated gate valve is our company cooperated with Shanghai University to research the high-quality green product, importing the advanced technology in Germany. And obtained the P&R&D item in No.3 in Shanghai, the new technology, new material, and new technics are applied that flat bottom type ,and static spray innocuity EP inside and outside surface of valve ,gate disc is covered with rubber etc. it is improve the seal capability, anti-corrosion, life-span and so on. This valve widely applied in the liquid pipes  for open or close  fixed in such table-water , sewage disposal, foodstuff and medicine ,air-condition system, fire protection system, building etc.

FEATURES

Treating with rubber

Both inner and outer are coated with advanced knowledge of rubber vulcanization to ensure  the elasticity of rubber  and make sure the exact geometry dimension. Rubber and ductile cast iron valve are together hardly. Which 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 stoprupture depend on the good mechanics capability of ductile iron .

Three "O" sealed ring

With the three "O"- rings, the leakage can be greatly reduced and the "O"- ring can bere placed under this condition with pressure and without stopping water. The thrust axle tree reduces the frictional resistance and lowers the operational torque. And it can be switch sealing 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 service.
