Resilient Wedge Gate Valve 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.

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. 

 

⊙ 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. 

 

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.
