Stainless Steel Bonnet Bolts Lightweight Resilient Seated Gate Valve

 

Resilient Seated Gate Valve 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.

 

Resilient seated gate valve to EN 1074-1 and 2 / EN 1171, with WRAS approved EPDM
rubber parts.

 

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.

Resilient Seated Gate Valve  FEATURES 

 

⊙ 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 . 

 

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.
