Viscosity effect on Relief Valves
Viscosity effect on Relief Valves
(OP)
I am looking into replacing several rupture disks with relief valves. The fluid is highly viscous (6,000-7,000 centipoise at 70F) and the flow is low (0.55 gpm). The fluid is 10% NaOH and 90% wetted cellulose in water and has a specific gravity of 1.12. I am not sure of the chance of the fluid hardening in the line and clogging the relief valve but am concerned this is a possibility. Is a relief valve a viable option for this scenario?

You did not mention if the application used was protecting "Code Vessels", but IF NOT you may want to consider a PSH (Pressure Switch High) to "trip" the energy source eliminating the overpressure. This scenario is used quite often in paper processes.
