Description
A cartridge valve designed as a normally closed, spool-type, proportional valve for use with a compensating element to provide an electrically variable pressure-compensated flow control.
Operation
As electrical current is applied to the coil, the spool will gradually shift from closed to open as current increases to 2 amps maximum. Flow will pass from port ➂ to port ➁ up to 300 psi differential.
Port ➀ is plugged.
The valve can also function as a differential control for load sense applications.
The valve functions with industry-common controllers which provide PWM current input to 2 amps @ 12 VDC.
OPERATION OF MANUAL OVERRIDE:
To override, push button in to activate. To return to normal function, release button.
Features and Benefits
- Valve controllers along with portable controller programming devices to vary PWM Duty Cycle, Ramp Time, Current Limit, Dither Frequency and Amplitude, can be provided by consulting the factory.
- Hardened precision spool and sleeve for long life.
- Efficient wet-armature construction.
- Cartridges are voltage interchangeable.
- Optional coil voltages and terminations.
- Industry common cavity
