2.1. Pre installation requisites 

 

1.

 

Important: Before performing any work on the valve make sure that all workers on site are familiar with the safety 
instructions and the relevant local and general safety instructions and work regulations. 

2.

 

Before installing the valve, flush the pipeline to remove scale, dirt and other particles that might affect the valve 
performance. 

3.

 

Carefully remove the valve from the shipping package. Unload all valves carefully to a sturdy level surface taking 
care not to drop them. 

4.

 

Valves fitted with hoist rings should only be lifted and conveyed using these hoist rings. 

5.

 

It is recommended that the valve be easily accessible as well as clearly marked to prevent damage.
