VALVE REMOVAL
Exiting medium! Ensure suitable isolations are in place upstream and downstream of the NeoFlow
installation to prevent release of pressure or continued flow of water.
► Ensure eye protection is worn at all times
► Use safe bolting practices. Undo lower bolts first to relieve any residual pressure and do not remove
until satisfied the line is depressurised and drained.
► Assume a protected position
► Securely collect the medium
a. Loosen and remove all flange bolts from around the valve in the pipe.
b. When all bolts have been removed, apply outward pressure on the mating flanges to release
the NeoFlow valve.
Exiting medium! If KH4 is open, the medium exits uncontrollably from the ball valve. This may lead to injury
or material damage.
► Assume a protected position.
► Only open ball valves slowly.
