Assemble the valve in the reverse sequence of disassembly.
During assembly, observe the following instructions:
• Lock the spacer nut (2) against the actuator rod (1).
• Tighten the nuts of the clamps at the control module with
a torque of 1 Nm.
• Tighten the nuts of the hinged clamps with following
torques:

• Tighten the nuts of the cast-semi-annular clamps with a
torque of 45 Nm (33 lbft).
Checking the valve stroke
• Actuate the valve by applying compressed air.
• Check whether the valve stroke (c) is correct.
