Lowering brake valves of this type series prevent hydraulic actuators from running ahead of the available oil supply. They are leakagefree and open independently of the load pressure by the pressure of the opposite side.


The newly developed MotionOne lowering brake valve is suitable for morors and cylinder applications and is the right choice when it comes to precisely controlling and positioning high loads of up to 600l/min. The modular design with the different control options guarantees maximum flexibility during installation. The MotionOne is suitable for applications with light to heavy oscillation. The newly developed damping cartridge is particularly suitable for applications that are highly susceptible to oscillations.In accordance with the modular design, users can essentially choose between standard covers with and without pressure relief valve, electrical proportional control or the newly developed damping cartridge for the MotionOne.


  • Suitable for cylinder- and whinch applications
  • Oscillation free load lowering
  • Very sensitive characteristics, especially at low speeds and high loads
  • Start of opening independent of the load pressure
  • Can be flange-mounted directly on SAE
  • Reliable closing of the lowering brake guaranteed by redundant springs
  • Smallest pressure loss (∆p) when lifting the load through the bypass check valve
  • Optimal damping behavior due to an additional path-dependent damping system already in the standard N version
  • A patented damping cartridge in version D is available for applications that are particularly susceptible to vibrations
  • The filter function is achieved via the shuttle valve on the inlet side
