Resistance of Zero D Valves

[quark]

Hi all,

Can anybody throw some light on resistance coefficients of zero deadleg valves (diaphragm type) in open(fully) and closed conditions? Or atleast, some methods or pointers?

Regards,

I believe all that info is on the George Fischer website. I assume you are talking about PVDF or CPVC valves for high-purity DI water?

These are Saunders SS valves, for high purity water. I have been through GF website but didn't get any info.

Thanks,

Not familiar with Saunders; if they are small-diameter UHP valves, Swagelok Nupro valves may be comparable:
