Product Description
Certification:WRAS / UL / CE / FM / ISO 9001
Resilient Seated Gate Valve With Gear / Worm / Lock / Extened Stem / Actuator
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
rubber.
Epoxy coating to DIN 30677-2 and GSK guidelines - internally and externally.
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 op
