WESSEL Pipe Rupture Valves TYP LHB-4K - compact design


In case of a pipe or tube rupture load control valves avoid uncontrolled movement of the cylinder. They also serve for an exact and stable positioning of the boom and enable sensitive and even movement processes. Load control valves can compensate for leakages on the main control valves in older construction machines. The type LHB 4-K is characterized by a very compact design and is therefore suitable for the smallest installation spaces.


  • Meets the requirements of standards: DIN24093, ISO 8643, EN 474
  • Sensitive control
  • Low hysteresis
  • Start opening independently of the load pressure
  • Can be flanged directly onto the SAE cylinder
  • Pressuring limiting valve with upstream filter sieve for protecting the cylinder
