Parts of Knife Gate Valve 

1. Body: Usually composed of stainless steel, cast iron, or ductile iron. 
2. Gate/Blade: The cutting-edge gate that slices through the media. 
3. Seat: Forms a snug seal and does not leak. 
4. Stem: Attaches the actuator to the gate. 
5. Actuator: May be manual, pneumatic, electric or hydraulic. 
6. Packing and Gland: Remains in place to avoid leakage around the stem area.

Working Mechanism 

The valve works by raising or lowering the gate to manage the flow of the media. As the handwheel or actuator is rotated, the blade is driven vertically by the stem. The gate is lifted completely out of the flow path while in the open position. The blade cuts through the media and rests tightly on the seat when in the closed position, preventing flow entirely.
