Function, section, symbols

General:

The 2/2-way proportional valve is a direct operated cartridge

spool valve. It controls the flow in proportion to the input signal

steplessly from to and from to .

Design:

The valve basically comprises of:

– Bush (6) with an external thread for the cavity

– Sleeve (3)

– Control spool (5) with compression spring

– Proportional solenoid (7) with central thread and

removable spool

Functional description (version “N” – normally closed):

– With a de-energised solenoid (7) the control spool (5), due

to the design the adjustment forces are always pressure

balanced, is held in the off-set position by the spring (8) and

therefore blocks the flow between and .

– By energising the solenoid (7) the control spool (5) is moved,

this movement is directly proportional to the electrical input

signal, and via orifice type cross-sections connects ports 1

and 2 with progressive flow characteristics.

– By de-energising the solenoid (7) the control spool (5) is

returned to the initial position by the spring (8).

– The hand override (4) makes it possible to switch the valve

without energising the solenoid.

1) Separate order2) Due to the occurring surface temperatures of the solenoid coils the European standards EN563 and EN982 must be taken into account!3) The cleanliness class stated for the components must be adhered too in hydraulic systems. Effective fi ltration prevents faults from occurring

and at the same time increases the component service life.

For the selection of fi lters see catalogue sheets RA 50 070,

RA 50 076 and RA 50 081.When connecting the electric, the protective

conductor (PE ) must be connected according

to the relevant regulations.
