    Soft Wedge Resilient Seated 10 Inch Gate Valve With SS316 Spindle For Chemical

    Soft Wedge Resilient Seated Gate Valve Flange End With SS316 Spindle For Sea Water


    Design features:

    With SS316 stem/ Spindle.


    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 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.

    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 .


    ⊙ 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

    servicing.


    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.
