Need Low dp check valve for gas flow
Need Low dp check valve for gas flow
(OP)
I have a gas discharging from a bag house fan into a vent line containing hot water vapor. No problem normally, but if the system shuts down, 300 F moist air/water vapor comes back into the bag house, causing caking fouling out the bags. Geometry makes a water seal a problem.
I have 6" wc dp allocated for cracking & frictional dp for 1500 cfm.
Who should I contact or kind of valve to evaluate

RE: Need Low dp check valve for gas flow
Suggest looking at Techno-chek dual flapper valve, as there were some in lightweight metal or plastic body designs. The Techno-chek product is now part of Cameron valves,

but detailed info might not be available on the site.

They are single direction and have a lightweight aluminum pallet. Usual cracking pressure is 1/2 oz. Higher pressues are achieved by weighting the pallet.
Among vendors you might consider: Groth, Varec, Protectoseal....
