Packless Graduated Valves, Ball-Check Return Elbows, Thermo-Nickel Return Traps, Air Exhausters, Vacuum Valves, Vacuum Pressure Gages, Differential Return Traps and Balanced Swing Check Valves. The operation of the "O-E" Perfect Vapor Vacuum-Pressure Sys tem is very simple: vapor generated at boiler passes up through, main supply pipe and is admitted to radiator at top through the " O-E " Packless Grad uated Valve. Water of condensation is returned to boiler through a 3^-in. "O-E" Elbow. In pass ing through the Elbow the water is first trapped by means of a wall or diaphragm cast in .the Elbow, outside of the radi- . ator, making a water seal which holds the vapor in radiator and prevents it from short circuiting into the return main. Should the Supply Valve of radiator be closed and con densation form a vacuum any water that might be in the return pipes is prevented from returning to radiator by the "O-E" Patent Elbow, which is equipped with a small brass ball operating on a smooth guide or track, and so arranged that when a vacuum takes place in radiator ball will immediately roll against port and dose it. Elbow is noise less in operation, as water seal is below ball, which is an important feature. As soon .as Supply Valve is again opened ball rolls off of seat allowing condensation and air to pass easily and freely into return main. An air vent is tapped in the slot of the screw stop in the return elbow which not only allows air to escape freely into return system when Supply Valve is open, but also equalizes the pressure on both sides of Water Seal, thus preventing it fromsyphoning out, which it might otherwise do. All air and con densation pass through main return pipe in base ment to a point above boiler where air is separated from water by means of "O-E" Patent Air Ex hauster. The "OE" Perfect Ball-Check Water Seal Union El bow with Adjustable Air Vent is made in two sizes. H-in., each $3.00. Ca pacity 250 sq'. ft. Ji-tn. Capacity 500 sq. ft. The "O-E" Improved Perfect Packless Gradu ated Valve is absolutely packless and never requires packing. It is tested by air and water test before, ship ment. It is quick opening, little more than one-half turn fully opens or closes it. Sand blasted and nickel plated. The handle being made of hard rubber, will not crack and is always cool' and easy to operate. The graduated dial and pointer admit of partial opening so that just the amount of heat desired can be obtained. All valves are fitted with composition disc on a swivel seat without extra charge. Graduated Supply Disc will be attached when specified, at slight additional cost. List Prices--H in.. $4.25; X in.. $5.00; 1 in., $6.00; IX in., $7.50. The "O-E" Improved Air Exhauster and Vacuum Valve is simple and very sensitive, operating as follows: Being connected at a high point above where the return main enters boiler, all air in the system seeks outlet at the Air Exhauster, which is open when there is any air in the system, and as soon as all air is exhausted and heat comes in contact with the Carbon Post in Exhauster, same expands and forces the Special Bronze Ball against the seat, closing the port. When closed system will cool slightly causing a vacuum which will hold ball on seat. As soon as vacuum is tost ball will roll away from seat and permit air to escape freely and quickly. The Improved cap locks the expansion post after it is properly adjusted and also holds post in a rigid hori zontal position. All Exhausters are set for ordinary use. but can be adjusted to suit any particular system to which they are attached. AH Exhausters are threaded for 1-in. I. P. both inlet and outlet. Made in one size only, 1-in., each $10.00. Ca pacity 2,500 sq. ft. We also announce the Thermo-Nickel Re turn Trap, a combination thermostatic trap with a ball-check and many new features.

A slight change of tem- perature causes a wide Radiator Trap Sarco open move ment of the valve. Its positive action keeps radiators thoroughly drained, preventing water hammer and air binding and increasing the heating value of every pound of coal burned. The life of the spirally corrugated ex pansion element in the Sarco exceeds many times that of annularly corrugated tubes because its movement at any point of the tube is so slight that it is hardly percep tible due to the stress in expansion and contraction being distributed evenly over the entire surface. Even if scale does reach the seat, it is practically impossible for it to collect there, for line contract only is had between the cone and seat of the valve. The Sarco can be shipped without ele ments so that when operating as a gravity system all the scale and dirt can be washed out. The elements can then be easily dropped into place and the trap will func tion perfectly. Removing the elements does not affect the adjustment because they are not at tached to the body or cap. The Sarco is factory adjusted. Brass castings are free from blow-holes or other defects and are exceptionally heavy. There is no danger of cracking or straining the trap when connecting same. Made in % and I in. sizes for vacuum, vapor and steam heating systems at pres sures up to 25 lb. Booklet 112 on request. SARCO TEMPERATURE REGULATOR Operated by an ex tremely sensitive liquid, the Sarco Temperature Regulators are instantly responsive to the sligh test fluctuations in the temperature of atmos phere or liquids. They are entirely self- contained and operated. No electrical, compressed air or other outside at tachments are required . for their operation There are no rubber or leather diaphrams or complicated perishable parts. The Sarco costs less than any other dependable control and is easily in- stalled. There is no cost Typ T- R 1 for operating. for Air Ducts Sarco Regulators oper- and Tanks ate steam, water and gas valves to. 6 in. They have 6 ft. of connecting tubing between elements, which can be increased where conditions necessitate. Supplied for any temperature between 30 and 300 deg. fahr. Ask for Booklet 77.
