Pneumatic diaphragm valve DIASTAR
4.3
Changing the position of the connections for the control pressure
The connections for the control pressure can be positioned in 90° increments, to optimally align it to the piping system.
DANGER!
Uncontrolled escape of the medium!
If the pressure in the piping system has not been completely relieved, the medium can escape in an uncontrolled manner. Depending
on the type of medium, risk of injury may exist.
► Completely relieve pressure in the pipe before opening.
► In case of harmful, inflammable, hot or explosive medium, completely empty and flush pipe. Possible residues must be taken
into account.
► Provide for safe collection of the medium by implementing appropriate measures (e.g. connection of a collection container).
► Drain the valve with the valve in the half-open position and collect the medium.
► Hazardous medium residues may remain in the valve despite drainage.
► Wear appropriate protective equipment.
