Valve bodies are designed to meet the demands of the residential, commercial and industrial sectors
• Thermostatic radiator valves regulate the flow of hot water or low pressure steam through free-standing radiators, baseboards or convectors in hot water and 2-pipe steam systems
• Valves are fitted with a packing gland assembly that is replaceable while the system is in operation
• EPDM rubber valve disc provides a seal against the valve seat at differential pressures of up to 15 psig in hot water heating systems, while 15 psig for low pressure steam systems
• Manual plastic cap supplied to protect the valve pusHPin and provide manual control of the valve during installation
• Valves remain normally open with no operator mounted
• Brass bonnet, spindle, nickel-plated brass tailpiece, union nut, EPDM disc, packing O-Ring, stainless steel spring,

• Atomizing noz.zles are available in a wide range of flow rates, all but eliminating the need for specially calibrated noz.zles. Between 1.00 GPH and 2.00 GPH, for example, seven different flow rates are available. Generally, with hot water and warm air heat, the smallest firing rate that will adequately heat the house on the coldest day is the proper size to use and the most economical. Short on-cycles result in low efficiency. Another guideline is to select the flow rate that provides a reasonable stack temperature regardless of the connected load. (According to the New England Fuel Institute, aim for a stack temperature of 400°F or lower on matched packaged units or 500°F or lower on conversion burners.) If the boiler or furnace is undersized for the load, it may be necessary to fire for the load and ignore the efficiency

• Spray angles are available from 30° through 90° in most noz.zle sizes to meet the requirements of a wide variety of burner air patterns and combustion chambers. Usually it is desirable to fit the spray angle to the air pattern of the burner. In todays flame retention burner, it is possible to fire more than one spray angle with good results. Generally, round or square combustion chambers should be fired with 70° to 90° noz.zles. Long, narrow chambers usually require 30° to 60° spray angles.

• Burner air patterns are much like noz.zle spray patterns in that they fall into the same general classifications, either hollow or solid. As you would expect, a burner with a hollow air pattern generally requires a hollow cone fuel noz.zle. A burner with a solid air pattern will give highest efficiency with a solid cone noz.zle, but the flame will probably be longer
