Description
Valve trim parts refer to the internal components of a valve that come into direct contact with the process fluid and control its flow. These parts are critical for the valve's performance and can vary depending on the valve type and application. Common valve trim parts include:
1. Valve Stem: Connects the actuator or handwheel to the valve disc or plug, allowing movement to open or close the valve.
2. Valve Seat: The surface against which the valve disc or plug seals when the valve is closed, preventing fluid flow.
3. Disc, Plug, or Ball: The movable element that regulates the flow by moving towards or away from the valve seat.
4. Cage: Guides the movement of the valve disc or plug and can also help control flow characteristics, such as reducing noise or turbulence.
5. Backseat: Provides a secondary seal to prevent leakage when the valve is fully open.
6. Bushings: Help reduce friction and wear on the valve stem during movement.
