The Mueller A17520 Service Valve is a heavy-duty brass compressor valve designed for critical flow control in commercial refrigeration and air conditioning systems

designed for air conditioning systems within that specific BTU range

Its lightweight yet durable construction allows for seamless integration into existing gas valve manifolds where zero minimum pressure differential is required for operation

the SC100W is engineered to minimize this through high-quality internal filtering

Siemens Building Technology QPA2060D Sensor 323613-751 Verify the complete HVAC equipmentThe Siemens QPA2060D is a dual function room air quality sensor engineered for precise demand controlled ventilation (DCV) in commercial HAVC systems. Utilizing infrared absorption technology (NDIR) for CO2 monitoring, this unit delivers a stable 0 10Vdc output signal across a detection range of 0 2000 PPM. The integrated temperature sensing capabilities allow for simultaneous climate monitoring, reducing the need for multiple wall mounted devices.
