Wessel - Model Type LHB-3R - Pipe Rupture Valve - Brochure

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 design LHB 3-R performs an internal regeneration circuit. The returning volume flow is dammed up by a check valve and routed into the rod side. The cylinder can thus be retracted without the need for a delivery rate of the pump. The regeneration function enables an increase in handling performance and at the same time reduces fuel consumption.
