Resilient Seated Gate Valve With Socket / Spigot End For PE / PVC / DI Pipe


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.


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.


The valve gate or closure member is typically in the form of a wedge made of cast iron material

so as to be sufficiently rugged so as to be suitable for high pressure and high flow applications.


In a resilient seat gate valve, the outer surface of the valve wedge is coated with an elastomeric

material so as to offer a bubble-tight seal even at elevated operating pressures.


The valve wedge is operated by turning a threaded stem so as to advance or retract the valve

wedge within the waterway of the valve housing.


Upon valve closure, the resilient material on the edge forms a bubble-tight seal with the internal

surface of the valve body. Dirt or other contamination in the valve operating system can lead to

incomplete sealing of the wedge or other malfunction.


Another object of the present invention is to provide a resilient seat gate valve having an

improved wedge operator system which readily overcomes the deleterious effects of contamination introduced either during construction or entrained within product carried to the valve.


These and other objects of the present invention which will become apparent from studying the

appended description and drawings are provided in a valve arrangement, that comprises a valve

housing that defines a water passageway and a valve seat within the valve passageway.


A valve wedge disposed within the housing passageway moves along a direction of operation

between a closed position in contact with the valve seat to block flow of water through the valve

passageway and an open position allowing flow of water through the valve passageway.


A pair of spaced apart tracks are disposed within the valve housing on either side of the wedge

and extend along the direction of operation. A pair of opposed wings carried on the valve wedge,

travel in each track. A valve stem coupled to the valve wedge moves the valve wedge in opposite reciprocating directions between valve open and valve closed positions.


Rollers are carried on the wings for rolling engagement with the tracks and scraper blades are

carried on the wings adjacent the rollers to scrape contamination from the tracks.


The tracks may be provided with or without a liner. If a wing is provided without rollers because of

a light loading application, for example, the track is preferably provided without a liner.


A light loading condition may arise, for example, at the upper end of a horizontally oriented

valve arrangement. However, under heavy loading conditions as, for example, at the bottom

end of a horizontally operated valve arrangement, it is preferred that the wings be provided

with load bearing rollers.


In this instance, it is also preferred that the track be provided with a liner of generally U-shaped

cross-section and made of a rugged material such as stainless steel.

⊙ 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



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.
