Knife Gate Valve

Speciality Valve your reputed Knife Gate Valve manufacturers in India. A knife gate valve is a type of valve designed primarily for on-off and isolation services in systems with thick fluids or where solid particles might be present. It gets its name from the sharp, knife-like edge on the gate that can cut through heavy slurries, viscous liquids, and even some solid materials, allowing for a clean shutoff. Knife gate valves have a thin, rectangular gate that slides in and out of the valve body, perpendicular to the flow direction.

The design of a knife gate valve is characterized by its slim, rectangular gate that slides vertically to control fluid flow. The gate is one of the most important parts; it is usually constructed of stainless steel or another sturdy material and has a sharp edge that can cut through things. The gate is housed and structural support is provided by the valve body, which is often made of cast iron, stainless steel, or other durable materials. When the gate is closed, the metal or elastomer seat guarantees a secure seal. The gate is raised and lowered by the actuator, which can be automated (electric, pneumatic, or hydraulic) or manual (handwheel). The stem, which joins the gate to the actuator, and different packing materials and seals to stop leaks and guarantee smooth operation are additional parts.

Types:
1.Through Conduit Knife Gate Valve
2.Uni Directional Knife Gate Valve
3.Bi Directional Knife Gate Valve
4.Slurry Knife Gate Valve
5.Flanged Knife Gate Valve

Working:
The actuator, which could be manual, pneumatic, hydraulic, or electric, lifts the gate when the valve is opened, enabling fluid to flow through the open flow path. The sharp edge of the gate efficiently slices through solids to provide unhindered flow. When the gate closes, the actuator lowers it back into the flow path, where it presses against metal seats or elastomers to form a tight seal that stops the flow. The gate’s self-cleaning edge removes any solid buildup, assisting in the maintenance of a dependable seal.
