HAWE Hydraulik

HAWE is a leading manufacturer of technologically advanced, high-quality hydraulic components and systems.

Directional Seated Valves


The seated valves and lifting modules are leakage-free and tight. Depending on the valve, they are actuated electro-magnetically, pressure-activated, mechanically or manually.



Pressure valves influence the pressure in hydraulic systems. Pressure-limiting valves (safety or overpressure valve) safeguard the system against excessive pressure or limit the operation pressure. Sequence valves generate a constant pressure difference between the inlet and outlet flow. A damping device is fitted as standard in the directly controlled valves to ensure quiet operation, but an undamped variant is also available for special operating conditions. Pressure-limiting valves with unit approval and CE mark are also available.

Valve Style MV, MVG, MVS, SV, SVC and DMV


HAWE Flow Divider


The flow dividers type TQ divide (collect) total flow entering (exiting) at port C. The distribution is independent of working pressure at ports A and B, and may be divided equally or unequally in predetermined portions. Type TV flow dividers feature privilege division. A variable flow entering at port C is divided into a partial flow QA, which is kept constant, and a residual flow QB. As soon as one consumer’s movement is stopped, the flow to the other is either reduced to a minimal flow (type TQ) or completely reduced to leakage flow (type TV). It is possible to overcome this design feature by simulating flow via a pressure-limiting valve. These valves are used for applications where one pump is required to supply two unevenly loaded hydraulic consumers, which must be driven simultaneously and independently (type TQ) or if one consumer simply requires a constant flow (type TV).


Releasable check valves


Check valves with hydraulic release are used to block one or both hydraulic consumer pipes or as a hydraulically actuated drain or circulation valve. The valves type RH and DRH are also available with pre-release for one or both sides of the connection to suppress decompression surges for circuits with high pressures and high consumer flows.

Type RH and DRH


Hawe Line rupture safety valve, Shuttle valves


The line rupture safety valves type LB is check valves. They are available as insert valves or with housing for pipe connection. The line rupture safety valve, which is generally mounted directly on the consumer (cylinder) serves to block a consumer in the event of a break in a pressurized pipe, i.e. if the hydraulic counter pressure subsides. It therefore prevents an uncontrolled decline in the load. A flow in excess of the set point results in a shim that has been lifted off the valve seat with spring force being pressed onto the housing seat by the flow forces, and consequently the valve closes. Two versions – one for completely stopping the load and one with an orifice hole for a slow decrease – enable this valve to be used for various requirements.

Type LB only


HAWE Radial Piston Pumps


The radial piston pumps consist of valve-controlled pump cylinders that are arranged radially. Higher volumetric flows can be achieved by arranging up to 6 radials in parallel. The pump is usually driven by an electric motor, which is connected to the pump via a flange and coupling. The closed pump housing allows for installation in a tank (hydraulic power pack) as well as installation outside a tank (motor pump). The possibility of a radial piston pump with several pressure outlets (several equal or different volumetric flows) is particularly innovative. Type RG with slide bearings is used in extreme operating conditions to increase the service life of the bearings. Compact control systems can be created by mounting various connection blocks and valve banks onto the cover plate of the hydraulic power packs.
