Description
The Xylem-McDonnell & Miller SA63-5 Bellows Assembly 63 Series is a mechanical sensing component used to control equipment to sense variations in pressure in fluid HVAC systems. It is blown or contracted with changes in water or air pressure, giving a movement to which other controls are applied to make switches or regulators. The pressure-sensing controls assist ensure proper detection of pressure conditions in the system and assure the performance of pumps, flow switches, and safety interlocks in both residential and commercial HVAC and plumbing systems.
