- Body: The main part of the valve that contains the internal components and provides the flow path for the fluid.
- Bonnet: The cover for the valve body that contains the packing and stem seal and provides access to internal parts for maintenance.
- Gate (or Disc): The part that moves up and down to open or close the valve, controlling the flow of fluid.
- Stem: The shaft that connects the actuator (handwheel or motor) to the gate, allowing the gate to move.
- Seat: The sealing surface inside the valve body against which the gate seals when the valve is closed.
- Packing: The material used to seal the space between the stem and the bonnet to prevent leakage.
- Handwheel or Actuator:
The device used to operate the valve. A handwheel is manually operated,
while an actuator can be powered (electric, pneumatic, or hydraulic).
- Yoke: The structure that supports the actuator and the top part of the stem, ensuring alignment and proper operation.
- Gland and Gland Flange: Components that compress the packing around the stem to maintain the seal.
- Backseat: A secondary seal that provides a seal between the stem and bonnet when the valve is fully open.

These components work together to ensure the proper operation and sealing of the gate valve.
