Product Description

Product Introduction

A knife gate valve (also known as a knife-type gate valve, slurry valve, or slide gate valve) is a linear stroke forced-sealing shut-off valve. Its core component is a flat gate plate with a knife edge, whose movement direction is perpendicular to the medium flow direction. It cuts off media containing particles, fibres, and viscous substances through the shearing action of the gate plate. The valve body has no traditional gate valve cavity, featuring an ultra-thin structure and a straight-through flow path. It is specially designed for media prone to clogging, such as slurry, pulp, mine tailings, dust, and sewage.

Product Features

1. Knife-type Gate Plate: With a bevelled edge, capable of cutting fibres, particles, and sludge to prevent clogging.

2. Straight-through Full Flow Path: Extremely low flow resistance, no dead corners, no material accumulation.

3. Ultra-thin Structure: Compact size, light weight, small installation footprint.

4. Reliable Sealing: Zero leakage with soft seal; high temperature resistance and wear resistance with hard seal.

5. Multiple Actuation Options: Manual / Electric / Pneumatic / Hydraulic, compatible with automatic control systems.

6. Easy Maintenance: Simple structure, seals can be replaced online.

7. Cost-Effective: Lower price than gate valves/ball valves, ideal for slurry applications.
