Wafer Type Slurry Knife Gate Valve
KGV-D wafer-type slurry knife gate valve, no packing required, with rubber lining, bidirectional flow, has a wide range of industrial applications. The full-bore non-interference flow channel design will form a blind plate cut-off when the valve is closed. The sealing surface of the valve is the surface between the two rubber sleeves pressed into the valve body cavity. Each rubber sleeve is molded in one piece and formed into an integral part with the liner reinforcement ring to ensure that the rubber sleeve is positioned in the valve body and helps it to withstand the high shear force generated when the valve plate passes through the two sealing villages. The sleeve should include a heavy-duty base ring design to support the sleeve in its installed position to avoid excessive pressure.

Size range:
15~2000mm, ½~84in
Pressure range:
1-10MPa, 1:2 safety factor, which means bursting pressure is 2 times higher than the operating pressure.
Material of valve body：
DN15~200 (carbon steel, ductile iron, aluminum alloy, stainless steel-casting process)；
DN250~2000 (45#steel, stainless steel welding technology )；
Material of valve sleeve：
NR, EPDM, CR(chloroprene rubber), NBR, butyl rubber, FPM, Hypalon rubber.
Explosion diagrams of components：
Full bore - no flow restrictions.
Shut off on the center line - extend the service lifetime of valve sleeve.
Valve sleeve is the only part in contact with the medium-the only wearing part.
Self-cleaning - no clogging.
Wide variety of material for valve sleeve-to fulfill the requests of fluid medium.
Strong construction design of metal valve body - extend service intervals.
Core of pinch valve is the rubber sleeve, which is the only part in contact with the process medium.
Customized design of valve sleeve according to customer's process conditions, prefer the optimal valve sleeve.
Basic type, extra thick type, high pressure type, Conical type, negative pressure resistant type
When service lifetime of pinch valve comes to end, it will become an almost new pinch valve after the valve sleeve is replaced.
Working status of pinch valve：
Fully-open: the full-bore elastic valve sleeve of pinch valve without any gaps & dead spots.
Center closed: closed on the center line of the valve body, which avoids turbulence and abrasion, as a result, the valve sleeve becomes a smooth and enclosed venturi with self-cleaning during every operation.
Fully-closed: it ensures the pinch valve is with no leakage of two ways when shut off, and the safe design of inner valve sleeve requires no maintenance of sealing elements.
