Super Capacity Pressure Relief Valves
Super Capacity Pressure Relief Valves
(OP)
FARRIS markets some super capacity PRV's with orifice sizes designated at U (31.5 in2), W, W2, X,Y,Z (176.7 in2).
Does anyone have experience with these ?
Are they acceptable? Do they meet codes?
What are the pros and cons?
We have a light hydrocarbon application with a set pressure of 50 psig that requires 17 8T10 conventional valves. Could a few of these larger PRV's be used as an alternative?

I agree that the weight is a consideration but the large number of 'T' size valves is more of a concern for us. We have used rupture-pin (Callidus) and buckling-pin (BS&B) devices in another installation and these are also very large and weighty. This is fairly inevitable (given the capacity requirements) if you are going to use fewer devices. The other devices have their own installation and maintenance issues, so there may be some preference to stay with the more widely accepted design of a much larger standard spring loaded valve.
