[. . . ] The valve is supplied with a screwed-on valve cap for manual operation and for protection of the system. This allows the system to be filled and set up for the initial heating / cooling during the building construction phase without the use of a controller or actuator. The medium flows through the valve from port A to port B, in the direction of the arrow mark on the valve body. The flow rate is limited by the setting of the valve plug (3), which is positioned either using the manually adjustable valve cap or by an actuator. In order to be able to close precisely against high pressure differences, the valve compensates pressure differences by means of a cone stem boring (5) connecting to a compensation chamber (6). Some specific actuators automatically retract the stem in the event of a power failure in order to close the valve and stop the flow of medium (refer to section "Actuators" on page 2). 1 4 5 2 3 A 6 B 1 valve insert 2 valve body 3 valve plug 4 return spring 5 cone stem boring 6 compensation chamber INSTALLATION When installing the valve, ensure that the flow direction corresponds with the arrow direction on the valve body (see Installation Instructions MU1B-0224GE51). · The valve must not be mounted with the stem pointing below the horizontal. · The valve should be installed stress-free. External threaded or welding connection sets are available (refer to section "Accessories" on page 5). · The installation of a strainer is strongly recommended; in district heating systems, it is obligatory. · Make sure that water hammers are avoided. · For pressure test, the valve (with actuator) must be open. · The adjustment cap must be removed from the valve only when an actuator is fitted. · The water must not contain more than 50% glycol according to VDI 2035 requirements.
