What is the temp rating on a 2" 800# class A105 globe valve@ 1975psi? I assume that the quoted class 800# should be a missprint, either class 600# or 900#, in accordance with API 6D.

Yes, reducing exit velocity reduces noise. In order to reduce the velocity, the flow area needs to expand in the direction of flow.

A Piston Actuator can be used in a unbalanced trim to counter Bath Tub Stopper effect instead of standard Spring & Diaphragm actuators.

Types of check valves

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
