5. INSTALLATION
5.1 General remarks on installation

The following points should be taken into account in addition to the general principles governing installation work:

ATTENTION!

- Before installation, make sure previous chapters are thoroughly followed. 
- Ensure safe access and working conditions for proper performance.
- Observe all applicable safety measures during installation.
- Remove fl ange covers or any other remaining packing/storage protection if present.
- Lay pipelines such that damaging transverse, bending and torsional forces are avoided.
- Protect valves from dirt during construction work. The interior of the valve and the pipeline must be free of foreign 
particles.
- Protect the valve soft parts from heating caused by welding works at the plant during commissioning.
- Avoid mechanical damage to the seat area.
- The valve is unidirectional. Follow the arrow in the body for installation. The valve can be installed either in vertical 
pipelines with normal fl ow upwards or in horizontal pipelines with cover upwards to allow proper working of the inside ball.

- Attention to utilization under low reverse pressure at ball closure, specially in the case of horizontal assembly, 
since this can lead to leakage in the reverse fl ow direction.
- There is a crushing hazard between the ball and the body. Ensure the ball is in rest position in case a hand is 
introduced inside the valve.
- When installing the valve, there is a crushing hazard between valve and pipe system. Mind the hands to avoid it.
