FUNCTION
SECTION VIEW
The proportional valves of the P4WE series
are direct-acting proportional valves.
The volume flow is controlled continuously
(proportionally) to the electrical input signal
at the solenoid coil.
The valve consists of a valve casing (1), a
control piston (2) and two proportional
solenoids (3).
According to the input signal, the solenoid
generates a force and shifts the piston
against a spring. This releases cross-
sections, which define the size of the
volume flow, depending on the pressure
difference at the relevant control element.
For electronical control of the coil there are
electronic controls available (see brochure
5.249.2).
Hint:
Vent system and valve before setting in
motion.
Caution:
The valves are available in 12V and 24V
coil versions. A 24VDC supplied control
electronics enables improved dynamic and
hysteresis values for a valve with 12V coil.
A control electronic supplied with 12VDC
can only be used in combination with a 12V
coil version. Then the dynamic advantage
of the valve is lost.

The performance curves represent typical flow curves for different valve spools. The first curve shows the flow value
at constant Δp, depending on the solenoid current. The second curve describes the dependency of flow value and Δp
at constant solenoid current.
The total valve pressure drop (Δp) was measured between port P and T of the valve.

MANUAL OVERRIDES
* Dimensions up to valve housing
In case of emergency, the valve can also be operated
manually. There are different forms of manual override
available.
The tank pressure should not exceed 50 bar. If the tank
pressure is higher, the force required to operate the
manual override increases accordingly.
For valves with two solenoids, simultaneous operation of
both manual overrides is not permitted.
