Securing Actuator to Valve
Before fitting actuator to the valve ensure that the actuator
and valve are in the same position. The position of the
actuator can be confirmed by either using the hand wheel
when fitted or by application of the electrical power supply
and use of a PDA.
A suitable mounting flange conforming to ISO 5211 or USA
standard MSS SP-101 depending on the actuator supplied
must be provided to mount the unit to the valve top
works assembly.
Actuator to mounting flange assembly fixings must conform
to Material Specification ISO Class 8.8. Delta GZ coated
Grade A4 stainless steel fixings are recommended.
Position actuator on to the valve mounting flange.
It may be necessary to adjust the position of the actuator to
enable alignment of the fixing bolts.
Tighten base fixings in accordance with Table 2.
NOTE: Should electrical operation be required to
set the stop bolts it will be necessary to connect
electrical power cables, establish Bluetooth
communication using a PDA or Smartphone then
carry out the Align Coupling Procedure.
