resilient seat gate valve


flanged gate valve

Anti -  corrosion  Resilient Seated Gate Valve with groove end for water 


Grooved-End Gate Valve is widely used in firefighting, building, metallurgy and etc.
Easy to install and service and Low cost


Resilient seat gate valves are employed in the transport of clean water. 


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.
