Hydraulic Knife Gate Valve

Hydraulic Knife Gate Valve is engineered for maximum thrust, rapid actuation, and heavy-duty isolation in high-pressure, high-viscosity industrial lines. Powered by hydraulic fluid pressure, this automated valve delivers exceptional force to shear cleanly through thick slurries, dense solids, and fibrous media that standard pneumatic or electric actuators cannot handle.

Designed with a compact wafer, lug, or flanged body, the hydraulic knife gate valve provides positive shut-off in extreme operating environments. Its heavy-duty linear hydraulic cylinder ensures consistent, high-torque gate travel even under severe differential pressures, making it critical for severe-service piping networks. Widely utilized in mining tailings, mineral processing, pulp and paper, and high-head wastewater systems, it provides reliable automated control and protection against line clogging.

Key Features

• Maximum Thrust Actuation: High-pressure hydraulic cylinder provides immense linear force to slice through dense, compacted solids and abrasive slurries.

• Heavy-Duty Beveled Gate: Hardened knife-edge blade shears through scale, fibers, and heavy particulates to ensure complete gate closure.

• Compact Low-Profile Design: Narrow face-to-face dimensions allow seamless installation in tight piping skids and space-constrained manifolds.

• Severe-Service Seating: Available with hardened metal-to-metal seats for abrasive slurry or resilient soft seats for zero-leakage isolation.

• Fail-Safe & Automation Ready: Easily paired with hydraulic accumulator units, solenoid control valves, and position sensors for fail-safe emergency trip systems.
