Canadian Representative: Railway and Engineering Specialties Limited, Montreal, Toronto, Winnipeg Automatic Controls Detroit Lubricator Company manufactures a very complete "j line of electrical controls, de signed to open or close an electrical circuit with changes j of temperature or pressure. The No. 411 Thermostat (illu strated) is a low voltage model and is made in plain and Day and Night types. All No. 414^ Thermostats are available with heat compensation to provide smooth, accurate temperature . No. 411 control. The No. 855 Mercoid Room Thermostat (illustrated) is a line voltage type-- available in heating, air conditioning and refrig eration ranges. For industrial use the No. 250 and No. 450 line of pressure and tem perature controls is available, in pressure No. 866 ranges from 20 in. vac. to 350 lbs, and in tem perature ranges from --30 F to 495 F. Write for Catalog No. 100-C. Furnace Controls Also available is a full line of blower controls, combination blower and limit controls, such as the CA-815 illustrated. There is a "Detroit" control available for practically every application where a dependable device is required to open or close an electrical circuit with changes of pressure or temperature. Write for com plete information. Our Engineering De partment is always ready to make recom mendations on any specific problem. Write for Catalog No. 100-C. No. CA8t6 Gas Valves The No. V- 570 Electric Gas Valve is an electrical ly operated valve for con trol of gas lines from % to lj^ in. It _____ provides par- No. v-6%0 tial opening upon initial operation, permitting quiet ignition of gas. Inexpensive, compact, and attractive in ap pearance, it employs an easily serviceable bimetal strip motor for actuating force. Write for Bulletin 201. The No. 566 Valve combines in one compact unit all of the functions of a control system for gas heating. AH safety functions are mechanical and operate independent of electric current. Adjustable for full snap or any degree of throttling action. Limit control closes . valve with a snap action. Valve may be manually operated in case of cur rent failure. Applicable to all gases, n a t,u r a 1 , manufac tured, or mixed. Write for Bulletin No. 80. Solenoid Valves "Detroit" Solenoid Valves for control of water, air, oil, gas, or refrigerant, embody many desirable features. A.C. hum is minimized and they will open against high pressures. Available in all standard volt ages and cycles A.C. or D.C. No. 683-3 (illustrated) is a small size valve with % in. connections. No. 681 is a pilot operated, intermediate size valve, and the No. 686 is a large pilot No. 688-s operated valve with 1124 Detroit Lubricator Company capacity up to IT tons Freon-12. No. 686 valve available with flanged connections. No. 681 and 686 are furnished with man ual opening feature to permit opening in case of current failure. All models may be taken apart and cleaned in the field without removing from pipe lines. Write for Bulletin No! 199. Controls and Instruments "Detroit" Thermostatic Expansion Valves "Detroit" Thermostatic Expansion Valves are designed to keep the evaporator in a refrigerating system completely re frigerated. Power elements are "gas charged" to a definite pressure, for motor overload protection; providing quicker response and more sensitive control. Capa cities from H to 20 tons Freon-12. All needles and seats are made of Delubaloy, a very hard, corrosion resistant alloy to insure long, trouble-free service. No. 673, the "standard of the industry," has a long record of dependability. It is sensitive and accurate in operation. No. 573 has the quality and operating charac teristics of the 673 for smaller installations. It has a single power element with double diaphragm. Write for catalog No. 200B for complete expansion valves listings. Refrigerant Distributors "Detroit" No. 790 Refrigerant Distribu tors insure a uniform supply of refrigerant to. all sections of multiple circuit evapo rators and are attached directly to the expansion valve by means of a flanged connection. These corrosion-resistant dis tributors are available for "Detroit" Ther mostatic Expansion Valves No. 786, No. 787, No. 788 and No. 899. They are made in five types of 2 to 18 passes for the above valves. All distributors are designed for use with in. O.D. copper outlet tubes. For complete capacity tables write for Bulletin No. 207. "Detroit" Float Valves for Vaporizing Oil Burners "Detroit" Expansion Valves These valves are of single diaphragm construction. The diaphragm is made of special alloy, care fully tested for flexibility to assure uniform capacities and smooth operation. Power elements are gas charged for protection against motor overload and for maximum sensitivity. Needles and seats are hard, corrosion resistant Delubaloy. Automatic and thermostatic types. in capacities from ^ to 20 tons Freon-12 and .9 to 36 tons methyl chloride. Write for Catalog No. 200-B. CRC-246 Single Metering Float Valve. The Greatest Improvement in Float Valve Design in Many Years. For space heaters, furnaces, floor fur naces, water heaters, ranges, etc., the CRC 246 mounts directly on the burner nipple, eliminating tee, fittings and tubing. Low flows are extremely accurate, assuring exact control of fuel delivery for low pilot burners. Rate of flow constant for inlet heads from 2 inches to 84 inches--elimi nates dying fire when fuel is low. Auto matic temperature compensation assures even fuel flow regardless of fuel tempera ture--an important "Detroit" feature. Magnetic trip mechanism is positive-- will not trip from vibration. Valve may be tilted a reasonable amount without affecting flow. Leveling by eye is satis factory. So simple to clean that servicing is no- problem. Write for Bulletin No. 217. 1125
