Function, section

Type 4WRE 6…-2X/…

Type 4WREE 6…-2X/…

The 4/2 and 4/3 proportional directional valves are direct operated components of subplate mounting design. They are operated by proportional solenoids with central thread and removalbe coil. The solenoids are optionally controlled by either external electronics (type 4WRE) or by the integrated electronics (type 4WREE).

Design:

The valve basically consists of:

– Housing (1) with mounting face

– Control spool (2) with compression springs (3 and 4) and spring plates (X1 and X2)

– Solenoids (5 and 6) and pole tubes (P1 and P2) with central thread

– Position transducer (7)

– Optional integrated control electronics (8)

– The mechanical zero point adjustment (9) is accessible via the Pg13.5 and the electrical zero point is accessible via the Pg7 (10) (type 4WREE)

Function:

– With the solenoids (5 and 6), de-energised, the control spool (2) is held in the central position by the compression springs (3 and 4) between the spring plates (X1 and X2)

– Direct operation of the control spool (2) by energising one of the proportional solenoids, e.g. control of solenoid "b" (6)

→ Movement of the control spool (2) to the left in proportion to the electrical input signal

→ Connection from P to A and B to T via orifice-like cross- sections with progressive flow characteristics

– De-energising of solenoids (6)

→ The control spool (2) is returned to the central position via the compression spring (3)

In the de-energised condition the spool (2) is held in a mechanical centre position by the solenoid return springs. This, for the spool symbol "V", does not relate to the hydraulic centre position! When the electrical valve closed loop control circuit is closed then the spool is positioned in the hydraulic centre position.

Note for type 4WRE 6…-2X/…

Draining of the tank line is to be prevented. Taking the insallation conditions into account a back pressure is to be fitted (back pressure approx. 2 bar).

Valve with 2 switching positions: (type 4WRE…A…)

The function of this valve version is basically the same as that of the valve with 3 switched positions. The 2 switched position valves are however only fitted with solenoid "a" (5). a plug (11) is fitted in place on the 2nd proportional solenoid.
