Knife Edge Gate Valve

Description

Knife Edge Gate Valve – Manual Operation | Industrial Supplier in Ahmedabad, India

Introduction to Knife Edge Gate Valve

A Knife Edge Gate Valve is a specialized isolation valve designed for applications involving slurry, pulp, viscous fluids, semi-solid media, and abrasive flow conditions. Unlike conventional gate valves, the knife edge gate valve uses a sharp-edged gate that can easily cut through thick media, solids, fibers, and suspended particles without clogging or jamming. This makes it an ideal valve for Indian industries dealing with challenging process fluids where standard valves fail frequently.

At Krishna Industries, Ahmedabad, Gujarat, we manufacture and supply high-quality manual knife edge gate valves specifically designed for Indian operating conditions. Our valves are widely used across cement plants, paper mills, sugar factories, wastewater treatment plants, mining units, power plants, chemical units, and bulk material handling systems throughout India.

This manual knife edge gate valve is operated using a handwheel mechanism, offering simple construction, easy maintenance, long service life, and cost-effective performance. The valve is suitable for on-off (isolation) service and is not intended for throttling applications.

Related product keywords commonly associated with this valve include: knife gate valve, slurry gate valve, manual gate valve, industrial isolation valve, wafer type knife gate valve. These related terms highlight the versatility and importance of knife edge gate valves in Indian process industries.

Krishna Industries focuses on delivering robust, affordable, and application-oriented knife edge gate valves for Indian buyers who demand durability, consistent quality, and dependable local support.

What is a Manual Knife Edge Gate Valve?

A manual knife edge gate valve is a linear motion valve in which a flat gate with a sharpened lower edge moves vertically to start or stop the flow. The sharpened “knife” edge allows the valve to slice through slurry, powder-laden liquids, fibrous pulp, and other difficult media commonly found in Indian industrial processes.

The manual operation is achieved using a handwheel connected to a rising or non-rising stem, depending on design. This manual mechanism is preferred in many Indian plants due to its simplicity, low maintenance, and independence from electrical or pneumatic power sources.
