Pneumatic and Spring PRV...
(OP)
Hi All,
Can a pnuematic pressure reducing valve (200-50 psig) working together with a spring pilot pressure reducing valve (50-15 psig)in the same pressure reducing station?
Thanks in advance.

I am not sure if I can have a pnuematic and spring load PRV in one pressure reducing station.
Thanks.

I agree that the scheme you mentioned would work fine, but before you go ahead, talk to your PRV manufacturer. It's possible he can recommend a multi-stage trim that would do the job within your existing valve body. That way you wouldn't need to mess with the upstream piping.

It is safe because if the first valve fails the second valve can handle the full pressure drop.
