Description
The Xylem-McDonnell & Miller SA64-2 Bellows Base Assembly is a control support component used in HVAC systems and boiler applications to enable pressure and level sensing within steam and hydronic equipment. It incorporates a bellows mechanism that reacts to system pressure or water level changes, transferring motion to connected safety and control elements for accurate response. The base assembly is designed for integration with compatible 64 series control units. It is fitted in boiler systems where it supports monitoring functions, assists in maintaining safe operating conditions, and ensures consistent control performance during continuous heating operation.
