The Siemens 277-03169 is a pneumatic actuator with a 1-1/2" normally open (NO) Valve for rapid and efficient control in HVAC systems. The body of the valve is made of bronze, thus making it tough while stainless steel is used as trim to avoid rust for long time use. The actuator pneumatic cylinder would open or close the valve depending air pressure applied by this particular actuator. This means that it gives you total control over operations in various large-scale HVAC installations like heating systems, air handling units and even cooling towers. As for ice cold conditioners or hot water heaters within given limit of temperatures ranging from 20°F to 250°F .In addition to these qualities mentioned above the unit has NPT threaded connections thereby ensuring proper fit without leaks when installed. The actuator provides an 8" stroke, enabling control over fluid flow with great precision within a wide range of motion.
