Through Conduit Knife Gate Valve

A through conduit knife gate valve provides a continuous, unobstructed bore when fully open, reducing internal pockets where solids can accumulate. Through Conduit Knife Gate Valve Suppliers in Nigeria can provide these valves for pipelines carrying slurry, bulk solids and other media where a clear flow passage and reliable isolation are required. 

Key Features

• Through-Conduit Bore: Provides a continuous passage through the valve when fully open.

• Reduced Solids Accumulation: Minimises internal cavities around the flow path.

• Knife-Edge Gate: Passes through solids and suspended material during closure.

• Bi-Directional Isolation: Suitable for flow from either direction.

• Low Flow Obstruction: Full-bore construction reduces restrictions when open.

• Automated Operation: Available with pneumatic or electric actuation.

Applications in Nigeria

Through-conduit knife gate valves are suitable for mining slurry, mineral processing, wastewater treatment, dredging, cement handling and solids-containing industrial pipelines, where preventing solids accumulation inside the valve is important.

Standards

Applicable requirements include MSS SP-81, with relevant flange, dimensional and pressure-testing requirements specified according to the valve configuration.

African Valve supplies through-conduit knife gate valves in Nigeria for slurry, wastewater, mining and bulk-material applications, where maintaining a clear bore is important for continuous material flow. The valve range includes through-conduit construction alongside other knife gate configurations for Nigerian industrial requirements.
