QXM Internal Gear Units
Description
Pump/motor operation in multi-quadrant applications
The QXM series is an extension of the QX pump series and is suitable for operation as both a pump and a motor. Thanks to the completely symmetrical design, these units can be used in multi-quadrant operation and are suitable for a wide range of applications in both industrial and mobile hydraulics. In 4-quadrant operation, the movement of cylinders can be controlled on the one hand, and exploited to recover/save energy on the other. For example, if the unit works as a pump during a lifting process, it can then work as a motor during the lowering process to feed energy back into the system.
Relief Logic Valves (LB)
These relief logic valves are used to protect pumps and control valves from excessive pressure and control the pressures of their hydraulic lines at constant levels. With the help of vent lines, they are also capable of remote and unload control.
Remote Control Relief Valves (DT-01 DG-01)
This valve is used as a remote control valve for pilot operated type pressure control valves.
Restrictors (SRT SRG SRCT SRCG)
This valve is used to regulate an actuator speed in a circuit where line pressure is almost steady and small fluctuation of oil flow due to pressure changes is permitted. Integrated check valve allows reversed free flow from outlet to inlet port. Pressure balanced construction provides less effort in adjustment at high pressure.
Seat Valves, SVH04
Description
These low-weight (aluminium) seat valve blocks are used to control single- or double acting cylinders. They are applied where high levels of leaktightness are required. The design uses a solenoid operated, direct acting, 2/2 bi-directional seat valve. They close the flow path to or from hydraulic actuators with virtually zero leakage.

Sectional Directional Valves, Series HDS…
Description
Series HDS directional control valves represents a flexible unit construction, the elements of which may be combined into one valve unit as required.
They are available in 8 different sizes, and with parallel, serial, serial/parallel, Load Sensing and Flow Sharing circuitry. In addition, the range includes inlet and intermediate flow control sections with either manual or electro-proportional operators. Where accurate control of speed and actuator position is needed, the valves satisfy the most complex hydraulic circuit requirements.
Shuttle Valves, Size 04…10
Description
Ball-type, screw-in design
Series WRVCG
The valve shuts off whichever one of the two inlet ports A and B is at the lower pressure. Port C is therefore connected with whichever one is at the higher pressure.
