Siemens 257-02009B 1/2" 2-Way Valve Assembly 2" Pneumatic Actuator 2.5Cv 3-8PSI N/C FxUM

Siemens 257-02009B Pneumatic Actuator 1/2" 2-Way Valve Assembly is a pneumatic actuator that is used to control accurate flow in HVAC systems. It successfully controls higher flow rates at 2.5Cv flow coefficient, within a 3-8 PSI spring range and meets ANSI Class 250 criteria for high pressure applications. The valve has 1/2" diameter, internal thread x union external thread connections for a stable and adaptable installation. It runs at temperatures from 35°F to 250°F and 1.61 pounds. This valve can be useful because it will regulate air or water flow on a commercial and industrial HVAC system significantly. The benefits of this include increased control accuracy, lower energy use, and a consistent climate management making for a stable and efficient interior environment.
