MATERIAL OF CONSTRUCTION
Body : Made up of one piece solid, rugged and heavy duty casting with flanges. Standard is Ductile Iron. SS 304, SS 316, SS 316L, Alloy 20, CD4MCu available on request.
Knife Gate : High tensile metal sheet SS 316L as standard. Alloy 20, Hestalloy etc available upon request.
Seat / Sleeve : Available in all materials as per requirement of application. Natural Rubber, Neoprene, EPDM, Viton, Hypalon etc.
Packing : Smooth well machined packing chambeer to provide iniform compression of packing and gives zero leakage. PTFE/high temperature graphite asbestos, food grade packing etc available as per application requirement.
Hand Wheel : Cast Iron, epoxy painted.
Application
Pinch valve finds its best application in handling corrosive slurry, abrasive media, liquid with solid suspensions and many others, which are difficult to handle with seat valve. Pinch valves are also best suited for Vacuum service
Range
The flange of the pinch valve can be supplied in accordance to BS, DIN, ASA & IS dimensions. The range for the valve is from 15 mm TO 300 mm. Higher size range can also be developed on request.
When open, the KGV Valve’s reinforced elastomer sleeves seal against each other and provide a 100% full-port opening which minimizes turbulence and wear. In this open position, the seats isolate and protect all metal parts of the valve from coming in contact with the process. When closed, the sleeves provide a drop-tight seal in both directions.
Available Sizes 3"-36"
Abrasivion-Resistant Slurry Sleeves are Field Replaceable, Provide Bi-directional, Drop-Tight Shut-off and Eliminate the Need for Packing

SUPERIOR SLEEVE DESIGN
JEC valve seat is made up of two highly resistant, long lasting sleeves made up of natural rubber with metallic core. It's well studied and patented hollow design allows for maximum flexibility on passing through the gate, minimizing the effort necessary for its operation.
The two sleeves are in permanent contact with each other so that there is total flow. Considering that the knife gate valve is specially designed to work with abrasive slurries, this design of sealing provides constant protection the body because the working media is not in direct contact with the body.
For easy maintenance the sleeves can be fully replaced from the outside of the valve as a complete unit and no need of flange rubber gaskets to make tightness between the valve and flanges.
