Protect your steam and hydronic heating systems from the damaging effects of vacuum conditions with the 401446 Hoffman Model 62 Vacuum Breaker. This precision-engineered valve is designed to automatically admit atmospheric pressure into the system whenever a vacuum occurs, effectively preventing potential collapse or siphoning of equipment. Relying on the trusted quality of Hoffman, this unit ensures seamless integration and long-term durability for demanding commercial and industrial environments.
The mechanism operates through an internal disc that remains tightly seated during normal positive pressure operation. Once the internal pressure drops below atmospheric levels, the valve immediately unseats, allowing air to enter the vessel and equalize the pressure. This simple yet critical process safeguards coils, heat exchangers, and tanks from the structural stresses associated with uncontrolled vacuum formation.
Key System Performance Baselines:
- Automatic Pressure Equalization: Immediate response to vacuum formation to protect piping and system integrity.
- Robust Construction: Engineered to withstand the rigors of industrial steam and hydronic fluid service.
- Reliable Sealing: Precision disc assembly ensures tight closure during standard system operation.
⚠️ Application Profile: Used primarily in steam coils, unit heaters, water heaters, and large piping loops to prevent system collapse, air-bound condensate, or fluid siphoning during shutdown cycles.
