PVC Valves must upgrade to Steel Valves? (ASAP)
(OP)
Dear Gentlemen,
We have 2 PVC Butterfly Valves, within rating parameters, in our Mechanical room within the steel pipelines of Chilled water Supply & Return (40-56F). Should I upgrade 2 PVC Valves to Steel material, should it be the same grade of steel in the pipelines? The PVC Valves are still brand new, just installed last year.
Thank you very much for your prompted response!

PVC butterfly valves are rated to 150psig@73F for sizes 12"NPS and less and 40F is within it's limitations.
Class 125 (good for 200WOG) cast iron body butterfly valves with EPDM or BUNA-N seats and a standard bronze or aluminum bronze disc would be your best bet provided your pressure is within it's parameters (I've see district chilled water at 230PSI)
