VACUUM BREAKER
Vacuum breaker is a spring loaded non return valve. When loading, the pressure of the product will push on the disc against the spring and close the vacuum breaker. When loading is finished and the product pressure lost, the spring will open the vacuum breaker. Air will enter the TLA through the vacuum breaker and gravity will help to push the product out of the arm.
GOOSE NECK
in case no vapour hose is attached to the cone, its vapour opening will receive this item; its shape will allow vapour to escape to the ambient, but at the same time preventing, avoiding rainwater to fall in the tank.
MANHOLE BRACKET + PRESS DOWN
The press down system prevents the loading arm from lifting out the manhole by reaction forces inflicted by the product flow. The manhole bracket prevents the loading arm dropping too low in the tank.
MANHOLE BRACKET + PNEUMATIC TOP LEVEL CONTROL + UP-DOWN MOVEMENTS & PRESS DOWN :
The press down system prevents the loading arm from lifting out the manhole by reaction forces inflicted by the product flow. The manhole bracket prevents the loading arm dropping too low in the tank and is used also as fixation point for the level sensor Detection of product high level is made by a pneumatic bubble pipe. The pneumatic cylinder for the press down will also be used to lift or lower the arm pneumatically
MANHOLE BRACKET + ELECTRIC TOP LEVEL CONTROL + UP-DOWN MOVEMENTS & PRESS DOWN :
The press down system prevents the loading arm from lifting out the manhole by reaction forces inflicted by the product flow. The manhole prevents the loading arm dropping too low in the tank and is used also as fixation point for the level sensor . Detection of product high level is made by a tuning fork – Endress & Hauser FTL 51 GGW2BB6G6C. The pneumatic cylinder for the press down will also be used to lift or lower the arm pneumatically
