1. Move the actuator A to the open position.
2. The actuator can be rotated 360°. The control medium
connectors can be in any position.
3. Lubricate the thread of the union nut a using a suitable
lubricant.
4. Place the actuator A on the valve body 1 approx. 90° anti-
clockwise to the end position of the control medium con-
nectors and screw it in hand-tight using the union nut a.
5. Tighten the union nut a with an open-end wrench (see
table below for torques). This rotates the actuator clock-
wise approx. 90° to the desired position.
6. Move the actuator A to the closed position. With the valve
fully assembled, check that it is working correctly and
that it is leak-tight.
