Stainless Steel SS304 Resilient Seated Gate Valve DN700 EPDM Gasket
the valve made by Stainless Steel SS304 , with resilient seat.
Stainless Steel SS304
Ductile cast iron + EPDM
Stainless Steel SS304
2Cr13 S.S.x 20Cr13
Ductile cast iron
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
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
⊙ Light weight
This body is made of ductile iron, it is 20%-30% lighter than the olds. Easily to fixing and
