Product Description
Knife Gate Valve is used to slice through sludge or sewerage and a gate is used fro normal positive shut off .It is a gate valve design that is distinguished from the standard design by the use of a simple metal plate for the gate and the absence of a bonnet; also called a slide valve.
Knife gate valve is a uni-directional or bi-directional valve designed for general industrial service applications. Knife gate valves used for pressure tight isolation of solid-liquid mixes in water and waste water treatment plants and pumping stations, paper and pulp plants, power plants and mining industry.
Product Parameters
- Valve Body: Features a cavity-free design. The gate slides within a side guide groove and presses against the valve seat to create a reliable seal.
- Bidirectional Sealing: The O-shaped valve seat enables bidirectional sealing, with options for rigid or elastic wedge gate to further enhance sealing effectiveness.
- Self-Sealing: Primarily seals with medium pressure, although an external force may be required for forced sealing in some applications.
- Installation: Recommended for vertical pipeline setups.
