EN 1074-1 And 2 / EN 1171 Standard EPDM Rubber Resilient Seated Gate Valve
Resilient Seated Gate Valve Design features:
Spindle’s gaskets O-ring - “DRY THREAD” - replaceable under pressure.
Stainless steel spindle with rolled thread and bearing.
Total sufrace rubbered wedge with replaceable spindle nut.
Gate valve with full bore.
All parts are protected against corrosion.
Resilient seated gate valve to EN 1074-1 and 2 / EN 1171, with WRAS approved EPDM
rubber parts.
Body and bonnet of GJS-500-7 (GGG-50). Wedge of ductile iron with fixed wedge nut,
fully vulcanized with EPDM rubber. Stem of stainless steel min. 13% Cr with rolled thread
and wedge stop ring.
Stem sealing with 4 O-rings in a nylon bearing, an EPDM rubber manchette, and a NBR
wiper ring. EPDM bonnet gasket in a groove, countersunk bonnet bolts encircled by the
bonnet gasket and sealed with hot melt. Sockets fitted with "Euro" sealing rings of EPDM
rubber.
Epoxy coating to DIN 30677-2 and GSK guidelines - internally and externally.

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.
