Functional Description
The directly controlled three-way two-position poppet
vavle is used to open or close the medium flow to the
consumer and, simultaneously, from the consumer to
discharge. A typical example is control of a single-action
cylinder. The control valve consists of the two seat bush (1),
poppet (2), return spring (3) and controlling solenoid (4).
Design 2S7 -when the coil is without current, the spring
forces the poppet into the rear seat (closer to the solenoid)
allowing free flow through canal 2 to canal 1 or vice versa.
Energizing the solenoid forces the poppet closing the front
seat. Will connect canals 1 and 2. Design 2s8 – in
de-energized mode, the spring forces the poppet through
the anchor to the front seat (away from the solenoid)
allowing free flow through canal 2 to canal 3 or vice versa.
Energizing the solenoid forces the poppet closing the rear
seat. Will connect canals 1 and 2. Coils are available for
both DC or AC voltage. The solenoid coil can be replaced or
adjusted up to 360 ° by loosening the fixing nut (5). The
solenoid is zinc coated.
Note: The valves are supplied without solenoid coils. The
solenoid coil, the terminal box and the housing body for line
mounting have to be ordered separately.
