Catalogue HY11-2500/UK 

Characteristics 

Function 

Proportional throttle valves are designed to include three 

stages. The main valve poppet is controlled by a hydraulic 

follower. The position of the hydraulic follower is determined 

in proportion to the input command signal 0-10V 

(optional 0-20mA). The main valve poppet follows the 

hydraulic follower. The pressure differential at the main 

valve poppet can be the maximum operating pressure. 

The flow direction is from B —> A. The main stage has no 

leakage in its closed position. 

The optimal dynamics are achieved at a control pressure 

of >50 bars. The adjustment precision of the flow rate is 

0.5% of the nominal flow rate. The maximum operating 

pressure at the ports A, B, and x is 350 bars. The 

hydraulic opening point is factory set for an input command 

signal of 300 mV (optional 0.6mA). 

Features 

• Pilot-controlled 2 position / 2 way directional flow 

control valve. 

Slip-in cartridge valve design. 

Mounting pattern according to ISO 7368. 

Control of large volume flows typical applications 

(presses and die-casting machines). 

Can be used for speed and position control. 

Fast step responses. 

Completely adapted unit with integrated electronics. 

Available with optional current input signal. 

In case of malfunction the valve closes automatically 

(fail safe).
