2. General product information 2.1 Description The TN2000 series of pneumatic piston actuators are suitable for use with DN15 to DN100 Spira-trol control valves of which three versions are available: Single-acting (with spring), Double-acting (with spring) and Double-acting (no spring). The availability of these three versions meets the requirements of valves at various differential pressures and in a variety of applications. - Page 7 11, 12 13, 14 Fig. 1 IM-P361-02-EN-ISS1 CTLS...

3. Installation Caution: Sling eyes (X, see Figure 3) are not to be used for lifting an actuated valve assembly. Sling eyes can only be used to stabilise the assembly. Suitable support of the valve and actuator will be required. See separate Installation and Maintenance Instructions for the control valve. - Page 12 3.1 Fitting the actuator (extend) to the valve Remove the screw and nut (13 and 14) then the rear and front clamp (11 and 12). Ensure the indicator scale is facing the same way as the valve name-plate. Apply the control signal pressure to the bottom of the actuator to bring the spindle (19) to the mid-travel position.

- Page 14 Tighten the mounting nut to 50 N m (36.9 lbf ft). The air supply to the actuator must be 'dry and free from oil'. Contact Spirax Sarco for more details with relation to composite tube/media compatibility. For high temperature conditions, insulate the control valve and pipework only to protect the actuator.

4. Commissioning Note: Before actioning any maintenance programme observe the 'Safety information' in Section 1. Warnings: 1. Actuator support will be required due to weight. 2. The actuator contains a pre-compressed spring. 3. Special assembly tool required. 4. Use POLYLUB GLY 801 (lubricating grease) only. The TN2000 series of pneumatic actuators are maintenance free. - Page 17 11, 12 13, 14 Only used Only used with the with the TN2_ _ _ _ _ TN2_ _ _ _C Fig. 7 IM-P361-02-EN-ISS1 CTLS...
- Page 18 4.2 Replacing the 'O' and 'X' rings (SE and DE actuators) Note: Remove the actuator from the valve as described in Section 4.1. Note: Depending on the actuator size there is either 3 or 4 short threaded bars which must be removed last to ensure that the spring tension is removed before taking the actuator apart.
- Page 19 4.3 Replacing the 'O' and 'X' rings (SR and DR actuators) Note: Remove the actuator from the valve as described in Section 4.1 Note: There are 5 long securing nuts that must be removed last to ensure that the spring tension is removed. Loosen and remove the connector (20), see Figure 9.
- Page 20 4.4 TN203_SEH or TN203_SRH (handwheel) Note: Ensure the handwheel has no comprehessive load on the actuator springs. Remove the plastic barrel plug (A), hold the actuator spindle at point (B) with a spanner and simultaneously loosen and remove the screw (C). Remove the handwheel (D), taking care not to displace the internal bearing (F).
- Page 21 4.5 TN215_SEH or SRH (handwheel) Note: Ensure the handwheel has no comprehensive load on the actuator springs. Rotating the handwheel clockwise retracts the spindle, rotating it anti-clockwise extends the spindle.
