This 7/8 x 1 1/8 suction service valve provides a reliable connection point for the low-pressure vapor refrigerant line traveling from the evaporator to the compressor

The Hoffman Controls 706-123SB is a robust

making it an ideal choice for low-flow applications such as fan coil units

provided the internal bore matches the capillary diameter

allowing for immediate status changes without disrupting the master schedule

Schneider Electric (Barber Colman) 2374-401 Relay Els PW 17895 This 7/8 x 1 1/8The Schneider Electric 2374 401 Air Motion Relay, formerly under the Barber Colman brand, is a critical pneumatic component engineered for precise HVAC air pressure sensing and airflow monitoring. Designed to function as a differential pressure switch, this device triggers a pneumatic signal based on the presence or absence of air velocity. It operates with a minimum 0. 15" W. C. setpoint, making it sensitive enough to detect subtle changes in suction
