The extension modules can be mounted to the IF32-Interface at the base plates and supply additional directional control valves.
There can be a maximum of three extension modules consecutively mounted to a base plate. There are several types of extension modules:
Extension module for CF-25-directional control valves (3 shown)
IF32-module with CF-25-interface four mounting sub plate mounted directional control valves
Extension module for CF-25-directional control valves and additional pump port
as above, but with additional SAE 1 ½“ pump port
Adaptor plate for SW18
IF32-module with SW18-interface for mounting sandwich-type directional control valves
Cover plate (1 shown)
Covers the interface leakage tight
Relief module
The relief module provides basic functions to protect the hydraulic system:
- LS pressure cut off (LS-PCO) with optional LS-PCO remote control (Remote LS-PCO).
- Unload valve (opens the pump path to the tank when the ΔpLS is exceeding 45 bar.
- LS drain (relieves the pressure in the LS line, when no directional control valve is activated).
These functions are integrated in the VT4 as standard.
