water valve

watervalve 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. Which 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 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. .
