Resideo V8043E1004 Valve 318172-701 This Siemens pneumatic valve assembly

This Siemens pneumatic valve assembly typically handles a close-off pressure of approximately 35 PSI when paired with the standard 2-inch pneumatic actuator

This 45 microfarad capacitor is a critical component for maintaining secondary winding phase displacement

the 20VA capacity is specifically designed to handle the increased power draw of Wi-Fi enabled thermostats and digital controllers requiring a constant common wire connection

Direct OEM Compatibility: Engineered as the exact replacement for 667277R

leading to lost functionality in specialized modes like I-FEEL or Econo Cool
