Barnes & Jones Vapor and Vacuum Systems of Steam Heating; Modulation Valves; Adjustable-Orifice Radiator Valves; Packless Quick-Opening Radiator Valves; Ther mostatic Radiator Traps; Thermostatic Trap Replacement Units; Condensators (Boiler Return Traps); Float and Thermostatic Traps; Strainers; Gages; Systems of Zone Control for Steam Heating. Complete Catalog on Request Vapor and Vacuum Series K--The Series K Valve is of the modulating type equipped with dial aDd pointer to indicate whether the valve is open or shut or in an intermediate position. Lever or wheel handle. Series F--The Series F Valve has no dial or pointer and is therefore furnished only with wheel handle or lock shield. Of same quality as Series K, but lower priced. Both Series K and Series F Valves are quick opening, have non-rising stems, renewable disc seats, of packless design. Made angle pattern in 1, and l in. sizes; straightway (globe) pattern in J and 1 in. sizes. For use in vapor or vacuum systems. Type H--The Type H Valve is of the adjustable orifice type so arranged that the dial indicates at all times the size of the radiator for which the valve is adjusted. May be adjusted with steam on the system. Noiseless in operation. Lever or wheel handle, unauthorized tampering virtually impossible. Made for pressure differentials of 1, 2, 3, 4 and 5 pounds, 1 in. valve up to 100 sq ft. 1 in. valve over 100 sq ft. Thermostatic Radiator Traps--The B A J precision made ther mostatic trap contains the unique, patented cage unit which is a complete operating unit in itself. The cage assembly contains the double thermostatic element calibrated in the factory, and locked in correct adjustment with the trap seat, which is also an integral part of the cage unit. Suitable for pressures up to 15 lb i to 1 in. Medium and high pressure traps suitable for pressures between 15 lb and 100 lb can be furnished. Float and Thermostatic Traps--Barnes & Jones F&T traps respond instantly to sudden loads and pass condensate, regard less of temperature, through water sealed float operated valve. Thermostatic element gives rapid air venting. Made in Low and Medium pressure ratings. All working parts are readily accessible. No special wrenches needed. No disconnecting of pipe lines, f to 2 in. Cage Units--Most maintenance engineers believe in a regular check-up of their heating systems. Barnes and Jones make this check-up easy by providing a means for testing all steam traps, and for replacing the actuating units of any make trap. The B & J cage unit replaces all working parts. The double diaphragm unit is correctly and permanently adjusted before leaving the factory. Made for all sizes, pressures and makes of vapor and vacuum traps up to 65 lbs. It's a complete one-piece replacement containing thermostatic element, valve piece and seat locked in unalterable adjustment. No field calibration is necessary. Ask for Bulletins C-$4 and /-44- Temperature Controls--"Proportionator" is the trade name applied to Barnes & Jones continuous How heating systems. Continuous flow of steam proportioned to the need. Continuous economy by using only as much steam as required and reduc ing the flow as the weather becomes milder. Continuous comfort because the radia tors at all times provide some heat so that the normal convection currents of air in a room are always active. There are no dead points. There is no "cold 70 deg" which is experienced in the ordinary "on-and-off" system. B & J controls are available for both vacuum and vapor systems. Ask for the bulletins. 1595
