Siemens Building Technology 268-03201 1/2" 3-Way Mix Valve Assembly 4" Pneumatic Actuator 3-8 PSI Equal Percentage Brass

The Siemens 268 03201 4” Pneumatic Actuator with the 1/2” 3 way mixing valve assembly is incorporated to meet the requirements of precise control in the HVAC system. The flow coefficient of this actuator is 4Cv and its 4" stroke provides for precise control of mixed air or water flows. It works in a spring range of 3-8 PSI and meets ANSI Class 250 criteria for reliable performance. The valve provided (brass, with the internal thread connection) is designed to operate at a temperature range from 20° to 250°F. Furthermore, this actuator is a perfect fit for commercial and industrial HVAC systems due to improved mixing and control, which means better system efficiency, increased comfort levels, and energy savings realized as airflow and temperature are optimised.
