Description

Electric Knife Gate Valve

Industrial Automation Flow Control Solution by Krishna Industries – Ahmedabad, Gujarat, India

Introduction

In modern process industries, automation is no longer optional—it is operationally critical. From wastewater treatment plants and pulp & paper mills to chemical processing units and bulk material handling systems, industries require reliable, low-maintenance, and automation-ready isolation valves capable of handling viscous, abrasive, and slurry-based media. The Electric Knife Gate Valve is engineered precisely for these demanding service conditions.

An electric knife gate valve combines the robust shutoff capability of a knife gate valve with the precision and automation efficiency of an electric actuator. Unlike conventional manual valves, this system provides remote control operation, precise positioning, and integration with PLC or SCADA systems. It is especially suitable for industries handling slurry, sludge, semi-solid materials, and fibrous media.

At Krishna Industries, we manufacture and supply high-performance electric knife gate valves designed for durability, corrosion resistance, and smooth operation. As a trusted industrial valve supplier based in Ahmedabad, Gujarat, India, we cater primarily to Indian buyers seeking dependable automation solutions for industrial flow control.

This product page provides complete technical insight, applications, specifications, FAQs, and procurement details for buyers evaluating electric knife gate valves.

What is an Electric Knife Gate Valve?

An Electric Knife Gate Valve is an automated isolation valve that uses an electrically powered actuator to raise or lower a sharp-edged gate (blade) to control flow.

It is widely used in applications where:

• Media contains solid particles
• Slurry or sludge flow must be isolated
• Remote operation is required
• Manual operation is impractical
• Integration with control systems is necessary

The sharp-edged gate slices through thick or abrasive media, ensuring reliable shut-off performance.
