Why Gas Absorption Piant Chose These R-P&C Valves Become of the plant1! isolated location the engineer! felt they should stendardixe on a type of valve which could be used on different Unei even though chemical tolutlons, temperatures, and pressures varied. The No. 6056 R-PaC Porged Steel Oate Valve proved to be the answer for several reasons. First of alt It has a pressure range from 380 lb*, at 1000* F., ,jj., up to 2000 lbs. at 100* F. Then with its chrome stainless trim and chromium plated disc, it has high resistance to corrosion. On top " of this, it's easy to service with its stainless steel gland bolts, and two-piece gland and follower. Best of oil, although the R-PkC Forged Steel Valve Is pre- \ mium quality it is NOT premium priced. It comes in sixes from ` to 2* with screwed or welding ends. If you use valves in these sixes, see your R-PoC distributor today or iu MARMADUKE mCmH*vW l(Mi post with such a crash that the evidently bent out like a bow and gj that propeller the hell back where`s came from.

With a 25-psi povl source, chemicals are discharged * about 1O0 psi; with a 100-psi aourc discharge is at about 900 psi. Capig ties range from 0.1 to 0.23 gpm et 12 strokes .per min. Powar-Orfvea Unit. The motor-drive variable-stroke pump, Fig. 5, has a fre floating plunger P, ranging in dlatnettj from % to 1 in. with stroke adjustsbk from 0 to 2 in. It runs at speeds upV 60 strokes per minute, pressures 4000 psi. Pump has a cylindrical crouhetd C driven by a connecting rod and const** throw crank. Stroke adjustment is msjji by sleeve S, threaded into the crotihea and onto drive-rod O.
