Block Valve in the Relieving Path of Fixed CO2 Extinguishing System
Block Valve in the Relieving Path of Fixed CO2 Extinguishing System
(OP)
NFPA 12 requires the installation of pressure relief device in closed piping sections of the fixed CO2 extinguishing system. My question is: Does the standard requires a block valve in the relieving path of the pressure relief device?

If you do put one there, be sure you can seal-lock it open.
We will design everything from now on using only S.I. units ... except for the pipe diameter. Unk. British engineer
