China High Pressure Stainless Lug Knife Wedge Sluice Gate Valve

Product Description

Product Description
Knife Gate Valve
Knife Gate Valves, or simply knife valves, are specialized valves designed to handle thick liquids, fibrous materials like pulp, or gases. They use a thin, blade-shaped gate to control the flow, moving perpendicular to the flow direction. When closed, the two sealing surfaces of the gate create a wedge, enabling a secure shut-off for enhanced control in demanding applications. Product Parameters
Structure and Sealing Options:
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. Product Features Control Flexibility: Operable locally or remotely, with options for customizable position display and centralized control. Lightweight Design: The carbon steel body is 20%-30% lighter than traditional gate valves, making installation and maintenance more manageable. Enhanced Sealing and Efficiency: Optimized for effective pipeline closure, minimizing leakage and boosting production efficiency. Material Durability: Sealing surfaces are crafted from wear-resistant, corrosion-resistant ceramic, which extends valve life and improves cost-effectiveness. Specification
