Intended use of the QL 326 

The QL 326 load valve is a further development of the proven QL 2xx load valve. The manually operated throttle 

valve was replaced by a proportional pressure relief valve with preamplifier. The excellent technical properties of 

the previous version (nominal pressure, maximum volume flow, error limits, etc.) were completely retained.  
The programming of the load valve is carried out either by the Hydrotechnik measuring device or by means of 

the available CAN commands when connected to an existing CAN bus. 
During operation of the load line, previously defined test parameters are transmitted to the control box via CAN 

bus. The control box controls the proportional valve. The load valve is capable of processing a defined load pro-

file (ramp or sine) as a single action or in several cycles. Identical loads can be run several times in succession. 
The load valve considerably simplifies the adjustment of pressure relief valves and the testing of pumps, e.g. the 

recording of the characteristic curve as a function of pressure, as a non-existent load can be simulated exactly 

and reproducibly.  
The components volume flow sensor (turbine) and proportional valve as well as measuring points for pressure 

and temperature are combined in one unit. The mechanical connection (inlet/outlet) is designed as a female 

thread ISO 150 228-G 1¼". 

For safe operation of the load line, we recommend the installation of an external pressure protection. 

This must be installed by the customer, e.g. by installing a pressure relief valve upstream of the load 

valve, or via the upstream hydraulic system.  

The device must not be used for control purposes. 

 

Commissioning 

 

 

 

Wear eye protection! 

 

Wear hand protec-

tion! 

 

 

 

 

 

 

 

 

Attention 
Damage to the turbine wheel possible! 

Commissioning and venting may only be carried out at a flow rate of max. 30 

l/min and a pressure of 30 bar. Otherwise, the turbine wheel can be dam-

aged by the air contained in the system. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Warning 
Hydraulic oil can blind you! 

Immediately after connecting the Minimess® measuring hose, the hydraulic 

oil contained in the system escapes from the hose. Take care not to get the 

oil in your eyes or on your skin. This can cause serious injuries such as 

blindness or skin irritation. Wear safety glasses and protective gloves! Have 

suitable collecting containers for the hydraulic oil ready!
