Differential pressure - 2 Way valve
Could I measure the differential pressure through the valve (DPv ) by: (DPv ) = Ps – DPcoil - Pr , like showed on the sketch below? Is it correct to measure this way? Or measuring by CBI through the STAD is it possible to measure the DPv ? What’s the right procedure to measure the valve DPv?
If the DH could be very higher is it necessary to install a modulating relief valve e.g BPV (TA) to reduce the differential pressure by a constant value?
Thanks in advance.
