4 INSTALLATION
WARNING!
Crushing hazard.
Do not put your hands or fingers inside the sleeve when the valve cycles.
Do not energize the actuator before the valve is properly attached to the pipeline.
Disconnect and de-energize the actuator before installation and maintenance work.
High pressure injection hazard.
Do not use higher pressure than rated for the valve. Higher pressures can cause serious damage to the valve or harm to operating personnel.
4.1 General
Flowrox valves are normally delivered fully assembled and ready for use. The valve can be installed either way in terms of flow
direction. Only personnel with appropriate training are allowed to install the valves. If the valve is delivered without an actuator
or accessories, they must be installed in accordance with the manufacturer’s instructions.
4.2 Flow direction, valve support and position
If the PVEG valve
with pneumatic (A)
actuator is installed horizontally, it must be supported to ensure smooth operation.
Support is also recommended when the valve is installed at any position other than vertical.
The support can be fixed on the wall (1), on the floor (2) or the pipeline (3). Also a simple rope, wire rope, chain etc. (4) can be
used to support the actuator (see drawing 2.).
The valve is bidirectional thus, can be installed in either way with respect to the flow direction.
