Unidirectional knife gate valve manufacturers in India
Speciality Valve is one of the prominent Unidirectional knife gate valve manufacturers in India, providing high-precision solutions for the processing of thick, viscous, and abrasive fluids. Our valves are constructed for harsh industrial duty where low-torque, linear movement shut-off in one direction is critical.
What is it?
A one-way knife gate valve is particularly intended to permit flow in a single direction and make a tight seal when shut off. It is suitable for slurries, wastewater, or pulp applications where there is a need for a strong shut-off action to avoid backflow and ensure system efficiency.
Why Required?
In semi-solid media industries, valves that can shear through heavy flow and seal dependably are of utmost importance. Unidirectional knife gate valves guarantee that the flow is one-way only, avoiding contamination and allowing safe system operation.
Key Components of Unidirectional Knife Gate Valve:
Knife-Shaped Gate: Shears through heavy media.
Body: Usually cast from cast iron, stainless steel, or ductile iron.
Seat: Metal or resilient seats to seal tightly.
Packing Gland: Stops leakage around the stem.
Actuator: Manual, pneumatic, or electric.
Working of Unidirectional Knife Gate Valve:
The valve works by raising a sharp-edged gate out of the path of flow. When the gate is dropped, it cuts through the media and pushes into the seat, forming a tight seal. Flow is permitted in only one direction, and reverse pressure has no influence on the sealing ability.
