of gravity! Please read instructions under 2.2 "Lifting"

3 Receiving Inspection

All ProCap valves leaving our facility are inspected and tested in accordance with the
relevant requirements. Valves equipped with actuators are subjected to functional
testing and are adjusted in such a manner that every unit is ready for direct installation
to the digester. However, NAF always recommend that a receiving inspection is to be
carried out.
We suggest the following inspection procedure:
• Check that the valve delivered is correct in terms of type, size, equipment,
etc.
• Examine the valve, actuator and valve accessories for possible damage
that may have occurred during transport.

4 Lifting and handling

When lifting the valve package, be aware of its weight and high centre of gravity!
All lifting must be carried out on the valve itself and not on the actuators, limit switches
or other accessories. The valve has a high centre of gravity and may rotate if the valve
is only lifted in the valve body necks. We recommend that the valve is lifted using a
minimum of 3 pcs high strenght lifting eye bolts. In order to better balance the valve to
an upright position, please use one lifting point around the upper valve body neck (near
