A. Stem sealing

Three independent stem seals offering triple safety:


A NBR wiper ring protects against dirt from outside.
A polyamid bearing with 4 NBR O-rings protects against galvanic corrosion.
An EPDM rubber manchette sealing acts as the main hydraulic seal to the flow.

B. Body/bonnet connection

The unique assembly of the valve body and bonnet ensures a durable tightness:


A round rubber bonnet gasket fits into a recess in the valve bonnet preventing it

from being blown out by pressure surges.

The stainless steel bonnet bolts are countersunk in the valve bonnet, encircled

by the bonnet gasket and sealed with hot melt. Thus there is no risk of corrosion

as the bolts are not exposed to the medium or soil.


C. Wedge nut

The fixed, integral wedge nut reduces the number of movable valve parts thus

minimizing the risk of corrosion and malfunction. The wedge nut is made of
dezincification resistant brass with lubricating abilities providing optimum compatibility

with the stainless steel stem.

D. Vulcanized wedge

The ductile iron core is fully vulcanized with drinking water approved EPDM rubber

internally and externally.


No iron parts are exposed to the medium and the excellent rubber vulcanization

prevents creeping corrosion underneath the rubber.


Guides in the wedge and on the valve body ensure a uniform closure regardless of

high pressure.


Safe operation is ensured, as the guides prevent overloading of the stem.


The wedge has a large through bore and as there are no hollows in the core, stagnant

water or impurities cannot collect and cause contamination.


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


Epoxy coating to DIN 30677-2 and GSK guidelines - internally and externally.




⊙ 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. 

⊙ American Standard

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.
