RESOL - Model VA300 -Changeover Valve

The valve RESOL VA300 is equipped with one input and two outputs. The influx is changed over to one of the two outputs in accordance with the position of the valve spindle. The positioning is effected by an electrothermal actuator (with manual emergency operation). The straight interconnection is normally closed whereas the connection opposite of the actuator is open. During the current flow through the actuator, the straight interconnection is opened and the connection opposite the actuator is closed. The state "normally closed" can be easily changed to "normally open". Because of the smooth adjustment there are no water hammers in the system and the flow rate remains constant. The 3-port valves RESOL VA300 are supplied with thread sockets made of brass.
