Bi Directional knife gate valve manufacturers in India

Speciality Valve is a well-known Bi-Directional knife gate valve manufacturers in India that offers high-performing, premium-quality valves that deliver sure shut-off in both directions of flow. Our valves can resist heavy media, abrasive, and corrosive media in extreme industrial conditions.

What is it?

A bi-directional valve knife gate is specifically used to control and direct the flow of media from both directions, unlike conventional unidirectional valves. This makes them extremely versatile and usable in those processes wherein direction of flow is non-uniform during operation.

Why Required?

In situations where fluid can move in both directions, a unidirectional valve cannot suffice. Knife gate bi-directional valves serve as a perfect solution by giving tight sealage on both sides, ensuring operation safety and effectiveness, and limiting the likelihood of leakage or backflow.

Key Parts of Bi Directional Knife Gate Valve:

Gate (Knife Disc): Edge-sharp blade used to cut solid-laden flow.

Body: Usually cast with stainless steel, cast iron, or carbon steel.

Seats: Two metal or tough seats for closing in either direction.

Stem and Packing: Prevents the leakage from the stem area.

Actuator: Hand, air, or electrical, depending upon the needs of the application.

Working of Bi Directional Knife Gate Valve:

The bi-directional knife gate valve operates by lifting or lowering a cutting gate into the media stream. Its double-seat sealing arrangement allows the valve to seal off flow from both directions. This is particularly beneficial in systems with reversing flow directions or frequent reversals.
