WESSEL Pipe Rupture Valves TYP LHB-4F - modular design

Description

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 load control valve in the modular design can be used for most standard applications. In contrast to the standard valve LHB-4N the port Z (cylinder) of the load control valve LHB-4F is flanged and thus interchangeable with other port sizes.

modular design. Various connection sizes for the cylinder port with the same main body
Start opening independent of the load pressure
Sensitive control with low hysteresis
Leakage-free
Load control valve piston pressure-compensated
Symmetrical connections to/from the control valve on the right and the left side of the load control valve
Can be flanged directly onto the cylinder connection
Surge line for parallel operation for the minimization of the cylinder pressure differences with construction size SAE 1“
Pressuring limiting valve with upstream filter sieve for protecting the cylinder
