Bevel Gear Rising Stem Through-Conduit Knife Gate Valve

The Bevel Gear Rising Stem Through-Conduit Knife Gate Valve is a heavy-duty isolation valve designed for large-diameter pipelines and abrasive service conditions. Featuring a through-conduit design, the gate fully retracts from the flow path when open, preventing media buildup, reducing turbulence, and extending seat life.

With the rising stem configuration, operators can easily monitor valve position. The addition of a bevel gear mechanism significantly reduces manual operating torque, making it especially suitable for large-bore valves (DN600 and above) or systems requiring frequent operation.

Key Features

Through-Conduit Design – Provides unobstructed flow when open and protects the sealing surfaces.
Bevel Gear Operation – Reduces manual torque, enabling effortless operation of large valves.
Rising Stem Design – Clear and visible indicator of valve open/close position.
Robust Construction – Built for heavy-duty applications with high-density or abrasive slurries.
Extended Seat Life – Minimal seat wear due to reduced contact with abrasive media.
Flexible Sealing Options – Available in uni-directional or bi-directional sealing designs.
