DESCRIPTION FEATURES

EN 5.231.2. 8_05.22

 High flow capacity due to optimized, cast casing

 Low hysteresis due to precision machining of moving parts

 With integrated Onboard Electronic and transducer

 Easy interchangeability due to internationally standardised interface

according to ISO 4401

HYDAC proportional directional

valves of the P4WERE series

combines directional control with

speed control of the consumer.

The controlled volume flow is

proportional to the electrical input

signal on valve electronics.

The integrated digital electronics in

combination with the transducer

allows improved performance and

function due to

- regulation of size and direction of

a volume flow

- short response times

- low hysteresis

- high repeatability

The proportional valves of the

P4WERE series are direct-acting

valves with integrated Onboard

Electronic.

The volume flow is controlled

continuously (proportionally) to the

electrical input signal at the solenoid

coil.

The valve constists of a valve casing

(1), a control piston (2), as well as a

transducer (5) and two proportional

solenoids (3).

The proportional solenoid coils are

controlled via the integrated Onboard

electronic (OBE) (4).

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.

LIN-BUS INTERFACE

Hint

We recommend the use of a metal connector to ensure electromagnetic compatibility (EMC) and to avoid

electromagnetic disturbances.

1) LED

2) USB Micro B socket

(cable with – length = 2 m -

in delivery)

3) Main connector with 7 Pin

In the casing of electronics, a 7-pole port for connecting with external devices is integrated.

The cable diameter for the main connector (cable and connector are not included in delivery) has to be min. 8 mm

and should be max. 10 mm.

Is also required for parameterisation of Onboard electronic

• The kit contains a test device with embedded connection

cable 7 pin and a USB cable for connection to the PC. The

dedicated software are available for download from our

website.

• The device is suitable for troubleshooting and functional

testing of HYDAC proportional valves with LIN-bus

interface.

• The software allow the check of settings, display the

diagnostic and permit to make changes on the standard

parameter setting made in factory, adapting it to your

system.

• No additional power supply is required: the device uses

the supply source from the 7 PIN system cable.
