between the subplate and the valve of the same nominal
size and is used for limiting the size of the main flow
(changing the speed of movement of the receiver).
Hydraulic fluid from the port

flows through the
throttling position both by the force of the spring and the
hydraulic force. The fluid returning from the receiver
moves the piston (5) to the right and allow free flow of
the fluid through the valve system (throttling insert)

INSTALLATION AND OPERATION REQUIREMENTS
1. Only fully functional and operational valve, properly
connected to electrical installation must be used.
2. During the period of operation must be kept fluid
viscosity acc. to requirements defined in this Data
Sheet - Operation Manual
3. In order to ensure failure free and safe operation the
following must be checked:
• proper working of the valve
• cleanliness of the hydraulic fluid
4. Due to heating of valve body to high temp., the valve
should be placed in such a way as to eliminate
