Size 6, symbol E, pneumatically actuated

Industrial hydraulic valve in a high performance range. Reliable switch-over of the oil flow direction according to hydraulic symbol.

Unpacked Weight: 1.506 kg

General information

Valves of type WP are fluidically actuated directional spool valves. They control the start, stop and direction of a flow.

The directional valves basically consist of housing (1), one or two actuation elements (2) (pneumatic actuation cylinder), control spool (3) and one or two return springs (4). The ports for the control are positioned radially (5).

When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except impulse spool).

The control spool (3) is moved to the desired spool position by means of the actuation elements.

Throttle insert

The use of a throttle insert is required when due to prevailing operating conditions, flows can occur during the switching processes, which exceed the performance limit of the valve.

It is inserted in channel P of the directional valve.

Without spring return, with detent,

version ..OF/..

Directional valves with pneumatic actuation are also available as a 2-spool position valve with detent (7). If actuation elements with detent are used, each spool position can be locked.

Without spring return,

version ..O/..

If actuation elements without return springs and without detent are used, there is no defined spool position in the de-energized state.

2) See characteristic curves
3) The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.

Performance limits

(measured with HLP46, ϑOil = 40 ±5 °C)

 

Notice!

The switching function of the valves is independent from the filtration due to the adhesive effect. To achieve the specified admissible flow values, a full flow filtration with 25 μm is recommended. The flow forces acting within the valves also influence the flow performance.

With 4-way directional valves, the specified flow data are therefore valid for normal operation with 2 directions of flow (e. g. from P to A and simultaneous return flow from B to T).

If there is only one direction of flow, the admissible flow may be significantly lower in critical cases (e. g. if a 4-way directional valve is used as a 3-way directional valve due to blocked port A or B).
