Trim
The internal parts of a valve which are in flowing contact with the controlled fluid. Can be designed to any of the following requirements:
Anti cavitation: reduces the tendency of the controlled liquid to cavitate. Anti noise: reduces the noise generated by fluid flowing through the valve.
Balanced: minimizes the net static and dynamic fluid flow forces acting on the trim.
Restricted or Reduced: has a flow area less than the full flow area for that valve.
Soft-seated: with an elastomeric, plastic or other readily deformable material used either in the closure component or seat ring to provide shutoff with minimal actuator forces.
