Jhly 20, 1973
Recently e bolt In the linestooe jinoeri our rot-ary airlock. The bolt scored the valve lining in several places before it Jaaned. I also noted that the end plates hare sone very deep cats from erosion. I'm afraid this valve eay becoee damaged beyond use la six Months to a years time.
*-*i. *.*.*>V
This is a custoa eade valve so if it goes oat ve coaid be down
for sometime.
.
Oar blow-through Talre has a 12 inch diaater, a 1 bp Motor and rotates at 2? RPM. It is rated at IS tons of ilMSstone per boar at $0f pocket fill.
*^
I would like to get a valve now so that when oar valve does go
oat we will only lose the tiae necessary for installation. This
should be a standard valve so that parts woald be readily
available. I woald also like to go to a drop through type to
redace the wear*

Considering the abort information I would recoamend a Seaeo Airlock Valve. It should hare adjostable blade tips and a closed end rotor so that air. could be purged on the end plates and bearings to ainlaise wear. This .. . will cost $112)0.00 for the valve, aotor, drive and the drop thru feeder.
