DESCRIPTION
Direct-acting proportional relief valve (pilot control valve) to limit system pressure. Operated by means of a band centerting spring and a removable proportional coil. The inside of the magnetic sleeve is connected to the main oil port 2 and filled with hydraulic oil. These valves are linked to control according to the electrical control values.
OPERATION
To set the system pressure, specify the control value at the cnotrol electronics. The electronic components required for operation drive the coil with current according to the control value. The hydraulic oil can flow from the main oil port 1 to 2. If the control value is zero, the minimum pressure is set.
Note: The generated return oil pressure (main port 2) is added to the set value of the main port 1.
FEATURES
* Direct-acting proportional valve to limit system pressure;
* Suitable for mobile and industrial applications;
* Operated by proportional coil with centering spring and detachable oil;
* Fine adjustment of the pressure characteristic curve of the control value at the control electronics, possibly from the outside;
