Slurry Knife Gate Valve

FREE-VALVE’s slurry knifegatevalves are designed for bi-directional tight on-offservice 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,theValves 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. Wear-resistant polyurethane inner lining.

3. Thepolyurethane lined has integral flange seals, eliminating flange gaskets when installing.

4. Resilient seats can be easily replaced after removing valve from the line.

5. Full port allows for high flow capacity with minimum pressure drop.

6. Valve plate use wear - resistant stainless steel plate with various types of wear - resistant surface treatment.
