Bard 8603-006 Valve

I have tho open system's that need 1" 24 volt valves. The problem is I need the valves to close slowly as not to have the pipes to rattle when closing. My systems are in my attic so noise is important. I am running about 16 gpm through it at 25-60 psi. Is this the valve I need?

It's probably best to talk to a contractor who has experience installing these valves so they know which one is the quietest one then we can help you ordering the one you need. We don't have any data regarding the noise they make when they close. Thank you.
