Siemens Building Technology 257-02068B Valve Assembly 320819-301 you know that consistent ignition

you know that consistent ignition and flame sensing are the backbone of any reliable gas heating system

With a robust 100VA power rating

you must physically depress the reset button after resolving the underlying heat dissipation issue

Replacing a warped or unbalanced blade with this precision HVAC motor fan prevents premature bearing failure in the condenser motor and ensures the system maintains its rated SEER performance

Automatic Zero Calibration: Pushbutton and remote zero-adjust terminals prevent sensor drift and minimize maintenance callbacks

Siemens Building Technology 257-02068B Valve Assembly 320819-301 you know that consistent ignitionThe Siemens 257 02068B is a high performance 3 way mixing valve assembly designed for terminal unit applications, featuring a 1 2 inch NPT connection and a 2. 5 Cv linear flow characteristic. This assembly integrates a Siemens 599 Powermite MT Series forged brass body with a rugged 2 inch pneumatic valve actuator, optimized for precise control of hot or chilled water in fan coil units and reheat coils. The spring return pneumatic actuator operates
