WESSEL Pipe Rupture Valves TYP LHB-3E

Description

The LHB-3E design offers the option of load compensation. If the volume flow with other designs increases with increasing pressure, this effect can be compensated or even overcompensated in this pipe rupture valve by additional valve technology. LHB-3E type valves are piloted hydraulically proportional or electrically proportional. A typical application is the luffing cylinder of mobile cranes.

Characteristics

  • 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
