General safety instructions General safety instructions 4 The control valves may only be mounted, started up or serviced by fully trained and qualified personnel, observing the accepted industry codes and practices. Make sure employees or third persons are not exposed to any danger. All safety instructions and warnings in these mounting and operating instructions, particularly those concerning assembly, start-up and maintenance, must be observed.
Design and principle of operation 1 Design and principle of operation The control valves consist of a single-seated Type 3222 Globe Valve and either a Type 5757, Type 5757-7 or Type 5724 Controller with Electric Actuator or a Type 5725 Controller with Electric Actuator with safety function. The process medium flows through the globe valve in the direction indicated by the arrow on the body.

Installation 2 Installation Caution! Versions designed to handle temperatures up to 200 °C must be fitted with the dark gray graphite supplied with the valve. Do not use the UDP seals available as accessories as they are only suitable for temperatures up to 150 °C. 2.
Attaching the actuator to the valve 3 Attaching the actuator to the valve If the actuator has not already been mounted on the valve by the manufacturer or when the original actuator on a valve is to be replaced with a controller with electric actuator, proceed as follows. Note! Fasten the actuator and valve together either at the valve connection or at the intermediate insulating piece, depending on the valve version, with a tightening torque of 20 Nm. 3.
Electrical connections 4 Electrical connections Upon installing the electrical cables, you are required to observe the regulations concerning electrical power installations according to DIN VDE 0100 as well as the regulations of your local power supplier. Use a suitable power supply to ensure that no dangerous voltages from the system or parts of the system reach the device in standard operation or in case of a fault.
Electrical connections AS 230 V, 50 Hz Domestic hot water heating in instantaneous heating system: The electric wiring options are the same as for the Type 5757 Controller with Electric Actuator, (see section 4.2). In addition, the pump control output can be configured as a fault alarm output.
Manual override 5 Type 5725 Manual override The direction of action and travel can be read off the travel indication scale. 5.1 Type 5757/-7 Controller with Electric Actuator Caution! Only activate the handwheel when the actuator is disconnected from the power supply. 4 Turn handwheel clockwise to extend the actuator stem 4 Turn handwheel counterclockwise to retract the actuator stem 5.2 Type 5724/5725 Controller with Electric Actuator Type 5724 Adjust the travel by turning the handwheel (approx.
Operation 6 Operation The controllers with electric actuators are adapted to the required control task by configuration and parameterization performed in TROVIS-VIEW Operator Interface: 4 Type 5757-7: TROVIS-VIEW 6661-1066 4 Type 5757: TROVIS-VIEW 6661-1062 4 Type 5724 and Type 5725: TROVISVIEW 6661-1060 Note! Instructions on how to operate the TROVIS-VIEW Operator Interface as well as on the function and parameter settings are contained in the Mounting and Operating Instructions EB 5757-7 EN, EB 5757
Maintenance 7 Maintenance The control valve is subject to natural wear. Depending on the conditions the valve is operated in, it needs to be checked at regular intervals. If leakage to the atmosphere occurs, remove the valve from the pipeline and replace the damaged parts. Warning! For maintenance work on the valve, make sure the relevant section of the pipeline is depressurized and, depending on the process medium, drained as well.
