Operating and installation instructions Pneumatic actuators - DP32 / DP33 / DP34 5.4 Control pressure connection The control pressure-connecting line is to be hooked up to the diaphragm base (pos. 7) during the „Spring closes“ operating mode and to the diaphragm cover (pos. 18) during the „actuator stem retracts by spring force“ operating mode. The threaded joint connection is the following. By actuators DP 32 and DP 33: G1/4“ and by the actuator DP 34: G3/8“.
PAGE 16
Operating and installation instructions Pneumatic actuators - DP32 / DP33 / DP34 5.6 Setting the starting point, operating mode „actuator stem extends by spring force“ - Set the actuator unit to the desired starting point of the spring range. - Screw the thread bush on the valve stem respectively screw the coupling flange on the actuator stem until the thread bush is fastened into the coupling flange. Simultaneously, the plug on the valve seat must also be tight.
