The VLP 12/C1 is a metric 12-size, normally-closed, vent-to-open, poppet-
type, spring biased dierential-sensing logic element. It will provide on/
o ow control from 1 to 2 based on the spring control pressure, inlet
pressure at port 1, and pilot pressure at port 3.
Rated pressure 315 bar [4500 psi]
Rated ow at 7 bar

The valve provides on/o, leakage-free control, suitable for use as a high ow
relief valve when piloted with a relief valve or a high ow unloading solenoid
when piloted with a small solenoid valve. Common applications include: pump
unloading, pilot-operated relief valve, sequence valve and selector circuit.
Eective use of logic elements is a key to designing cost-eective circuits, and is
limited only by the imagination of the designer.
