What is Valve Trim?
The removable and replaceable internal parts of the valve that come in contact with the flow medium are collectively known as valve trim. Disc, valve seat, and stem are common for all the valve. Valve Trim components will change with types of valve. Valve specific trim includes back seat, glands, spacers, guides, bushings, retaining pins and internal springs. Here in the image, you can see the gate valve trim parts. Because of the trim parts, disk movement and flow control are possible.
