VALVE VACUUM BREAKER 1/2
The VB100 vacuum breaker is used in top loading arms, fitted downstream of the dead man valve to ensure that a vacuum can not form in the drop tube which would result in retained product and possible environmental contamination, particularly with heavy or viscous products.
A spring loaded poppet opens at a set pressure to allow air into the top of the drop tube to stop vacuum forming and prevent a product hang-up.
No in-field adjustment is necessary with pre-set vacuum settings according to type.
FEATURES Depressing the cap opens the poppet and allows flushing of the seat without removing from service.
TECHNICAL DATA VB100 opens at 1-2 kPa vacuum. (Gravity systems) VB100U opens at 35 kPa vacuum (Pump systems) Orifice equal to 6mm dia hole
