Product description

FREE-VALVE’s High Abrasion-Resistant Polyurethane Lining Knife Gate Valves are designed 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 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 ideally suited 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 liner has integral flange seals, eliminating flange gaskets when installing.

3. Polyurethane liner can be replaceable in all sizes on site.

4. 2PC split body construction for ease of maintenance,lower the cost of ownership.A sealing ring is arranged between the valve body and the polyurethane lining to prevent medium leakage,which facilitates the protection of the surrounding environment.

5. The wear-resistant polyurethane lined is formed by integral pouring, and the valve body is designed as a split type, which is easy to replace the polyurethane lined.

6. Full port designing, after the valve is fully opened, the valve disc is fully lifted to the polyurethane inner chamber, the valve disc does not contact directly with the medium, avoiding the wear caused by the medium erosion of the valve disc.

7. Valve disc can be made of wear - resistant stainless steel plate with various types of wear - resistant surface treatment.
