EPDM Rubber Resilient Seated Gate Valve EN 1074-1 And 2 / EN 1171 Standard
Description:
Resilient seated NRS gate valve is a wedge gate valve and Non-rising stem type, and suitable for use with water and neutral liquids (sewage) . The non-rising stem design ensures the stem thread is adequately lubricated by the water passing through the valve.
Characteristic:
-On-line replacement of top seal: Easy installation and maintenance.
-Integral rubber-clad disc: The ductile iron frame work is thermal-clad integrally with high performance rubber. Ensuring tight seal and rust prevention.
-Integrated brass nut: By means of special casting process. the brass stem nut is integrated with the disc with secure connection, thus the products is safe and reliable.
-Flat-bottom seat: The sealing surface of the body is flat without hollow, avoiding any dirt deposit.
Application:
Water supply system, water treatment, sewage disposal, food processing, fire protection system, natural gas, liquefied gas system etc.

Resilient Seated Gate Valve 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.
⊙ 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.
Applications : This valve widely applied in the liquid pipes for opening or closing fixing in such
water, sewage disposal, electric power, energetics pipe , chemical, shipping, energy sources etc.

⊙ 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 .
