Resilient Seated Gate Valve Introduction
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.

Resilient Seated Gate Valve FEATURES
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.
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.
