Kronos Walvoil SDE030 + HmLine proportional control box

Hydraulic Valve Walvoil SDE030 12/24V with 6 Proportional Sections, Open Center.

Control Boxes 12/24V. We adapt the control fully to the customer's requirements. The number of functions, the method of control (switches, buttons, potentiometers; both returning or not returning to neutral), the type of control (proportional or on/off and floating functions), the voltage (12/24V) and the type of plugs. The arrangement of the functions on the box itself can also be agreed with us.

This kit is configured for the most popular machine settings, supporting up to 6 standard small crane functions. If you require a different dedicated configuration, we can customize it to meet your needs. Please send us a diagram, and we can assist further.

We provide technical support and are readily available via email, whatsup and telephone.

Feel free to contact us at - or - for any inquiries or assistance.
