Through-Going Knife Gate Valves for Slurry, Pulp & Severe-Service Applications

The KV Controls DT Series Through-Going Knife Gate Valve is specifically designed for severe-service slurry, pulp, wastewater and solids handling applications requiring unobstructed flow and reliable shut-off performance. Engineered with a full-port through-going design and cavity-free body construction, the DT Series minimizes media build-up, reduces flow resistance and improves operational reliability in demanding industrial process systems.

The DT Series is ideally suited for pulp slurry handling, residue discharge, sewage treatment and solids-laden process media commonly found in mining, pulp & paper and wastewater treatment applications. Its robust construction and self-compensating seat design provide excellent abrasion resistance and extended service life under difficult operating conditions.

Available in manual, pneumatic and automated configurations, the DT Series knife gate valve delivers dependable isolation performance for severe industrial applications.

What Is a Through-Going Knife Gate Valve?

A through-going knife gate valve is a full-port isolation valve designed to provide unrestricted media flow while reducing the risk of product build-up and clogging inside the valve body. Unlike conventional cavity-style knife gate valves, the DT Series features a two-piece cavity-free body design that allows solids, fibers and slurry media to pass through the valve more efficiently.

This design improves flow performance and operational reliability in applications involving slurry, pulp stock, sewage, fibrous media and abrasive solids handling systems.

Full-Port Flow Design

The DT Series features a full-port through-going configuration that minimizes flow restriction and allows unobstructed media passage during operation.

Reduced Media Build-Up

The cavity-free valve body design helps prevent product accumulation and reduces the risk of clogging in solids-laden process systems.

Reliable Isolation Performance

The DT Series provides dependable shut-off performance in severe-service applications involving slurry, sewage, pulp stock and abrasive process media.
