FREE-VALVEâ??s slurry valves are idea for bi-directional tight on-off service in abrasive slurry applications,the valve adopts the full-lined wear-resistant polyurethane injecting with the whole mold, and all media passing areas are wrapped in the polyurethane lined to achieve all-round wear-resistant protection,which provides excellent wear life with 100% positive shutoff of abrasive slurry,the Valves are designed for applications in mining. Features 1.Bi-directional flow,zero Leakage and shut-off, allowing valves to be installed in either direction. 2.The polyurethane lined has integral flange seals, eliminating flange gaskets when installing. 3.Resilient seats can be easily replaced after removing valve from the line. 4.Full round port allows for high flow capacity with minimum pressure drop. 5.Valve plate use wear - resistant stainless steel plate with various types of wear - resistant surface treatment. 6.Wafer type can also be made if necessary Technical Specification 1) Size Range: DN50~DN600 2) Pressure Range: PN6~PN16 3) Connection Type: Wafer,Flange 4) Seat and lined material:Polyurethane (PU) 5) Body material:WCB, CF8 ,CF8M 6) Pressure test:GB/T13927, MSS SP-81 7) Face to Face: GB/T12221, MSS SP-81 8) Operation Method:Handwheel, Lever, Bevel Gear, Chain Wheel, Pneumatic, Electric 10) Service temperature:-20�°C to 80�°C Applications FREE-VALVEâ??s slurry knife gate valve is designed and equipped to handle tough and abrasive shut off applications involving slurries, powders or granular substances as well as pulp stock, paper and recycled paper.Mining and minerals processing,Pulp and paper applications,Water & waste water,Sand and gravel plants,Tailing lines,Abrasive slurry materials
