Ideas for damping fluid borne noise?
(OP)
Looking at a refrigeration loop on a vehicle with a shut off valve. When the valve opens or closes, a clunk is heard by the passengers. Considering rubber damper for mounting, any ideas for in line fitting type suppression?

the second thing that comes to mind was advice my dad gave me way back when I bought my first car - an old jalopy, he said "if it makes to much noise, just turn up the radio"
best of luck,

- internal valve changes to reduce the speed of opening.
- muffler upstream of valve in high pressure line.
- resilient hose in circuit to absorb fluid energy.
The best performing and most cost effective solution was a sharp edged orifice in the high pressure line just upstream of the shut off valve.
