Overview of proportional 4/2- and 4/3-way directional spool valve type
POL, PRL, PIL
Proportional directional spool valves are a type of directional valve. They control the
direction of movement and the velocity of individual or multiple hydraulic consumers
actuated simultaneously. Control is infinitely adjustable.
The directional spool valve type POL, PRL and PIL is a 4/2- or 4/3-way directional
spool valve with standard connection pattern NG 6 (CETOP 3) and NG 10 (CETOP 5).
It is directly actuated and proportionally activated.
The directional spool valve is available for manifold mounting. Intended applications
include industrial hydraulics, in particular machine tools.

Installation, operation and maintenance information
Observe the document B 5488 “General operating instructions for assembly, commissioning, and maintenance.”
5.1 Intended use
This productis intended exclusively for hydraulic applications (uid technology).
The user must observe the safety measures and warnings in this document.
Essential requirements for the product to function correctly and safely:
All information in this documentation must be observed. This applies in particular to all safety measures and warnings.
The product must only be assembled and put into operation by specialist personnel.
The product must only be operated within the specied technical parameters described in detail in this document.
All components must be suitable for the operating conditions when using an assembly.
The operating instructions for the components, assemblies and the specic complete system must also always be observed.
If the product can no longer be operated safely:
1. Remove the product from operation and mark it accordingly.
✓
It is then not permitted to continue using or operating the product.
5.2 Assembly information
The product must only be installed in the complete system with standard and compliant connection components (screw ttings, hoses,
pipes, xtures etc.).
The product must be shut down correctly prior to disassembly (in particular in combination with hydraulic accumulators).
DANGER
Sudden movement of the hydraulic drives when disassembled incorrectly
Risk of serious injury or death
Depressurise the hydraulic system.
Perform safety measures in preparation for maintenance.
5.3 Operating instructions
Observe product configuration and pressure/ow rate.
The statements and technical parameters in this document must be strictly observed.
The instructions for the complete technical system must also always be followed.
NOTICE
Read the documentation carefully before usage.
The documentation must be accessible to the operating and maintenance staff at all times.
Keep documentation up to date after every addition or update.
CAUTION
Overloading components due to incorrect pressure settings.
Risk of minor injury. Parts may burst or y off, and uncontrolled leakage of hydraulic uid.
■
Pay attention to the maximum operating pressure of the pump, valves and ttings.
■
Always monitor the pressure gauge when setting and changing the pressure.
38/41 D 6394 - 06-2024 - 1.1 HAWE Hydraulik SE
Purity and ltering of the hydraulic uid
Fine contamination can significantly impair the function of the product. Contamination can cause irreparable damage.
Examples of ne contamination include:
■
Swarf
■
Rubber particles from hoses and seals
■
Dirt due to assembly and maintenance
■
Mechanical debris
■
Chemical ageing of the hydraulic uid
NOTICE
New hydraulic uid from the manufacturer may not have therequired purity.
Damage to the product is possible.
Filter new hydraulic uid to a high quality when lling.
Do not mix hydraulic uids. Always use hydraulic uid that is from the same manufacturer, of the same type, and with the
