The HAWE spool valve (directional or proportional) combine more than two valve blocks together to control multiple actuating elements. It can combine safety valve, overload valve, oil supply valve, flow distributing valve, single directional valve, etc, according to the different requirements of the hydraulic system. Learn more at their official website:

It features in compact structure, simple oil pipeline, less compression loss and easy installation.

According to the oil pipeline connection, the directional spool valves can be divided into parallel connected valve, series connected valve and hybrid connected valve.


Bi-directional solenoid for HAWE directional spool valve

The bi-directional solenoid has two types, on-off solenoid, and proportional solenoid. Both are specially designed to match with multi-directional spool valves like HAWE and other brand.

The shape of the solenoid curve is “climbing type”. The output force is in direct proportion to the current within the range of rated travel and rated current.

It can help to the hydraulic system to realize stepless speed regulation as well as remote control. Below are the technical data of the bi-directional on-off or proportional solenoid:
