DESCRIPTION
Spirax Sarco Combination Vacuum Breaker/Balanced Pressure Thermostatic Air Vent, Combination Vacuum Breaker and Balanced Pressure, 1/2 in NPT, 200 psi, 450 deg F, Cast Iron, 6.87 in H x 5.53 in W
The VB-VS Vacuum Breaker/Air Vent is designed for use on steam systems to remove air and other non-condensable gases, which may impair heat transfer during start-up and normal operation, and admit air when system drops in vacuum.
This steam vacuum breaker can be maintained without disturbing the inlet piping connections, however, complete isolation is required before service is
performed as well as the vs combo vent must be cooled down first.
The VB-BS vacuum breaker should be inspected and cleaned periodically. Worn or damaged parts, especially the valve head and seat, should be replaced. See below for VB-VS Combo spare parts.
