Manual Handwheel Rising Stem Through-Conduit Knife Gate Valve

The Manual Handwheel Rising Stem Through-Conduit Knife Gate Valve is designed for reliable shut-off and smooth flow control in pipelines handling abrasive slurries, viscous fluids, and solids-laden media. Unlike standard knife gate valves, the through-conduit design allows the gate to fully withdraw from the flow path when open, minimizing turbulence, preventing media buildup, and extending seat life.

The rising stem design provides a clear visual indication of the valve’s position, while the manual handwheel actuation ensures simple, dependable operation without requiring external power. This valve is widely used in industries such as mining, wastewater treatment, and power generation where durability and reliability are essential.

Key Features

Through-Conduit Design – Gate retracts completely from the flow path, reducing wear and preventing blockages.
Rising Stem Operation – Provides a clear, visible indicator of valve position.
Manual Handwheel Actuation – Simple, cost-effective, and low-maintenance operation method.
Heavy-Duty Construction – Built to withstand highly abrasive, high-density slurry applications.
Seat Protection – Extended seat life due to minimal contact with abrasive media when valve is open.
Service Flexibility – Available in uni-directional or bi-directional sealing designs.
