By accepting and expelling water volume fluctuations during heating and cooling cycles

Serviceability: Precision-machined internal seating ensures a leak-free seal during long-term operation

allowing the system to resume operation once temperatures have dropped below the differential threshold

preventing catastrophic valve-to-piston contact

Durable Construction: Lightweight aluminum blower wheel design resists corrosion and prevents excessive strain on motor bearings
