Preparation
WARNING!
BEFORE ANY INSTALLATION AND MAINTENANCE WORK CAN
COMMENCE ENSURE THE VALVE AND SURROUNDING SYSTEM IS
DRAINED OF PRESSURE AND ISOLATED.
Remove the headwork before installation and cover the top of the body to protect the internals of the
valve from particulate contamination.
Also ensure that enough room is left above / around the valve for the headwork once this is replaced
after installation.
Identify the intended flow direction and match the valve orientation with its flow direction arrow.
Ensure that all end connections to the valve are in line and that the pipe work is supported to reduce
unwanted stresses, loading and vibration on the valve and system pipe work.
Ensure that all joining materials / components used during the installation of the valve are compatible,
and will not cause any deterioration to the valve structure.
