PROPORTIONAL DIRECTIONAL VALVE 4WREE10W25-2X/G24K31/F1V

Size 10, symbol W, electrical with integrated electronics, 24 V DC

Industrial hydraulic valve in the high performance range; reliable control of the oil flow direction according to the hydraulic symbol; high accuracy through internal piston position feedback

Unpacked Weight: 6.241 kg

Direct operated proportional directional valve with electrical position feedback and integrated electronics (OBE) Control of flow direction and size Operation by means of proportional solenoids with central thread and detachable coil For subplate mounting: Porting pattern according to ISO 4401 Spring-centered control spool

Type 4WREE...-2X/...

The 4/2 and 4/3 proportional directional valves are designed as direct operated devices in plate design. Operation by means of proportional solenoids with central thread and detachable coil. The solenoids are controlled via integrated electronics.

Set-up:

The valve basically consists of:

Housing (1) with connection surface

Control spool (2) with compression springs (3 and 4) and spring plates (5 and 6)

Solenoids (7 and 8) with central thread

Position transducer (9)

Integrated electronics (13)

Electrical zero point adjustment (12), accessible via Pg7

Function:

With de-energized solenoids (7 and 8), central position of the control spool (2) due to compression springs (3 and 4) between the spring plates (5 and 6)

Direct actuation of the control spool (2) by the control of one proportional solenoid, e. g. solenoid "b" (8)

→ Control spool (2) is moved to the left in proportion to the electrical input signal

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

flow characteristics

Switching off of the solenoid (8)

→ Control spool (2) is returned to the central position by the compression spring (3)

In the de-energized state, the control spool (2) is held in a mechanical central position by the return springs of the solenoids. With control spool symbol "V", this position does not correspond to the hydraulic central position! When the electric valve control loop is closed, the control spool is positioned in the hydraulic central position.

Important notice:

The PG fitting (11) must not be opened. Mechanical adjustment of the adjustment nut located below is prohibited and damages the valve!

Valve with two spool positions: (Type 4WREE...A...)

The function of this valve version basically corresponds to the valve with three spool positions. The 2 spool position valve is, however, only equipped with solenoid “a” (7). Instead of the 2nd proportional solenoid, a plug screw (10) is installed.

Notice:

Due to the design principle, internal leakage which may increase over the life cycle is inherent to the valves.

Notice:

The tank line must not be allowed to run empty. With corresponding installation conditions, a preload valve (preload pressure approx. 2 bar) must be installed.

Command value:
Positive command value 0 ... +10 V (or 12 ... 20 mA) at D and reference potential at E cause flow from P → A and B → T.
Negative command value 0 ... –10 V (or 12 ... 4 mA) at D and reference potential at E cause flow from P → B and A → T.
With valves with 1 solenoid on side a (e.g. variant EA and WA), a positive command value 0 ... +10 V (or 4 ... 20 mA) at D and reference potential at E result in flow from P → B and A → T.
Actual value:
Actual value 0 ... +10 V (or 12 ... 20 mA) at F and reference potential at C result in flow from P → A and B → T.
Actual value 0 ... –10 V (or 4 ... 12 mA) result in flow from P → B and A → T.
With valves with 1 solenoid, a positive actual value 0 ... +10V (or 4 ... 20 mA) at F and reference potential at C result in flow from P → B and A → T.
Connection cable: Recommendation:
up to 25 m cable length type LiYCY 7 x 0.75 mm²
up to 50 m cable length type LiYCY 7 x 1.0 mm²
External diameter see sketch of mating connector
Connect shield to PE only on the supply side.

Notice:

Electrical signals provided via control electronics (e. g. actual value) must not be used for switching off safety-relevant machine functions.
