5" WC for natural gas but can be adjusted to meet specific equipment requirements during commissioning

the 7-BM is physically compatible but adds the required manual reset safety protocol often mandated by local boiler codes for larger steam plants

Designed for long-term reliability in high-cycle heating applications

the valve is rated for fluid temperatures ranging from 35°F to 281°F

exceeding its maximum burst pressure can deform the internal diaphragm and affect calibration

Schneider Electric (Barber Colman) 2220-053 Temperature Transmitter 326010-701 5" WC for natural gasThe Schneider Electric 2220 053 Room Temperature Transmitter is a robust pneumatic temperature sensor designed for precise HVAC automation control. Functioning as a high performance proportional transmitter, this unit converts room ambient temperatures into a 3 to 15 psi pneumatic signal, ensuring seamless integration with legacy Barber Colman pneumatic system architectures. It serves as the direct engineered replacement for the TP2220 052 and TP2220
