The hose burst valves in the normal operating allow the flow in both directions without influencing the regular functinality of the hydrulic system. In event of breaking of the hose, the plate joins the body and the valve close the outlet flow from the cylinder, locking the load in its position. Hose burst valves must be set by regulating the opening thickness “F” (see technical data sheet of the valve). It is recommended a setting correspondant to a flow 50% over the maximum of the system. The setting can be done in our plant or directly by the Customer. As optional, a calibrated orifice on the plate allows the slow lowering of the load when the valve is closed. Components of the hose burst valves are protected against corrosion with surface treatment zinc plating.
