4. Principle of operation
Series 854 Ball Float Valve controls discharge of water into a tank or reservoir in response to
water level variations. The float mechanism holds the valve closed until the water levels drops,
the float then follows the water level matching inflow to outflow. If the outflow ceases, the water
level will rise and the float close the valve.
5. Health and safety at work
Make sure all relevant Health and Safety issues and regulations are adhered to prior to and
during installation or maintenance work carried out on this product. It is the end user's
responsibility to ensure that safe working practices are followed at all times.
Whenever AVK’s products are installed, operated or maintained the inherent dangers of
pressurised liquids and gasses must be addressed. Before work on a valve or other piping
component is undertaken, that may involve the release of internal pressure, the valve or line
must be fully isolated, depressurised and drained prior to commencing the work. FAILURE TO
COMPLY WITH THIS MAY RESULT IN SEVERE INJURY OR DEATH.
