Product Overview | 1199 Series
APPLICATION The North American 1199 Motorized Direct Acting Valve is designed for highly accurate modulating control of industrial process heating applications. These prepackaged, motorized valves are engineered for precision and are ideal for combustion systems that require dependable, automated control. They are particularly well suited to applications requiring a high degree of modulating accuracy and repeatability and can cost effectively meet your unique flow control requirements. The versatility, performance, accuracy, and superior design of the 1199 motorized valve assemblies can significantly enhance quality and performance. DESCRIPTION The 1199 assemblies consist of a high resolution, precision actuator direct-coupled to a characterizable adjustable port or butterfly valve. The direct-coupled feature eliminates the use of valve to actuator linkage, allowing short setup time and eliminating flow changes due to mechanical variations associated with valve linkage. This direct-acting feature also helps improve performance by consistently positioning valves relative to the control signal. The compact, easy to install assembly reduces setup time and greatly simplifies replacement of existing control valves. Valves are precision built and designed for control of natural gas, oil, or combustion air. Externally visible position indication is standard on all valves and motors. Different valve styles are available in a variety of body and pipe sizes to accommodate system flow require- ments and control needs .
