Piston flow switch VD series

magneticcapacitivefor water

The volume flow raises a piston (fitted with a magnet) out from a valve seat against a spring force. The piston actuates a hermetically separated reed switch. ●Highly reproducible ●Precise, stepless adjustment of the switching value ●Insensitive to dirt ●Short installation length Handling and opération Note • - Include straight calming section of 5 x DN in inlet and outlet • - Include a filter if the media are dirty (use magnetic filter for ferritic components). • It must be ensured that the values given for voltage, current, and power are not exceeded. • - When switched on, a load must be connected in sériés. • - The electrical détails apply to ohmic loads. Capacitive, inductive and lamp loads must be operated using a protective circuit. Adjustment To adjust the switching point, the fixing screw for the switching head must be loosened. The switching head can then be rotated. Turning to the right increases the switching point, and vice-versa. Then retighten the fixing screw.
