VB 100 VACUUM BREAKER
TERMINAL > LOADING > ACCESSORIES
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.
MOUNTING
In to 12mm BSP female socket. Ensure poppet head is level with the inner end of the socket thread inside the pipe when fitted in order to maximise flow area.
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
MATERIAL
Brass body, polyurethane cap, stainless steel spring
Poppet is Delrin / Seal is Viton
