Installation10 EB 8331-3 EN3 Installation3.1 Mounting positionInstallation depends on the mounting positionof the valve. The actuator must not be sus-pended to hang downwards.3.2 Attachment to the valve3.2.1 Construction with inte-grated yokeFig. 1A: Attachment to– Series V2001 Valves (DN 15 to 80)– Type 3260 (DN 65 to 150)– Type 3214 (DN 65 to 100)1. Remove protective covers and unscrew nut(6) from the valve.2. Retract actuator stem using the manualoverride. Refer to section 5.3. Place actuator on yoke and fasten tightusing nut (6, 36 mm width across flats)(tightening torque min. 150 Nm).4. When the plug stem (5) fits closely on-to the actuator stem (3), attach both stemconnector clamps (4) and fasten withscrews.3.2.2 Construction with ringnutFig. 1B: Attachment to Series 240 Valves1. Push plug stem down to close the valve.2. Turn the stem connector nut (8) until themeasurement x = 75 mm (DN 100 andlarger: x = 90 mm) from the top of theyoke to the head of the stem connectornut (8) is achieved. Lock this position withthe lock nut (9).3. Retract actuator stem using the manualoverride. Refer to section 5.4. Place actuator onto the valve and secureusing the ring nut (7).5. When the stem connector nut (8) rests onthe actuator stem, attach both stem con-nector clamps (4) and fasten with screws.6. Move actuator stem (3) to the end posi-tion (valve closed) using the manual over-ride or motor.7. Align travel indicator scale (10) to themiddle of the stem connector (4) andscrew tight.Fig. 1C:Attachment to Type 3214 (DN 125 to 250)1. Retract actuator stem using the manualoverride. Refer to section 5.2. Place actuator onto the valve and secureusing the ring nut (7). If necessary, retractthe actuator stem slightly beforehand usingthe manual override.3. When the plug stem fits closely onto theactuator stem (3), attach both stem con-nector clamps (4) and fasten with screws.4. Move actuator stem (3) to the end posi-tion (valve closed) using the manual over-ride or motor.5. Align travel indicator scale (10) to themiddle of the stem connector (4) andscrew tight.
