With larger diameters (> 300 mm), heavy actuators (pneumatic, electric, etc.), or with the valve
installed horizontally (B) or at an angle (C) on a horizontal pipeline, the installation will require
the construction of suitable supports. (See the following diagram and consult the technical
department at Orbinox).

In vertical pipelines, the construction of suitable supports is always required (for further
information please consult the technical department at Orbinox).
Once the valve is installed, test that the flanges have been fastened correctly and that all
electrical and/or pneumatic connections have been properly made.
Where electric accessories are mounted on the valve (i.e. solenoid valves, electro-pneumatic
positioners, etc.), the valve must be earthed correctly before being put into operation.
First, operate the valve with no flow in the pipeline. Then test operation and valve seal with
flow. It should be noted that the packing material might settle in shipping/storage, which can
cause minor leakage. This can be remedied by tightening the gland follower (5) during
installation. Once performance has been tested, the valve can be put into operation.
