Hydraulic Distributors are technologically quite complex, and according to their function are operated mechanically, hydraulically, electrically or by a combined method. A hydraulic valve malfunction, during operation can be a serious problem, due to their complexity and differences, determining the exact cause for the failure is a challenge.
There is a wide verity of hydraulic distributors used in modern mechanics. During the operation of a hydraulic system, minimal downtime is not just desirable, but a necessary requirement.
The most optimal solution to solve the problem seems to be to replace the defectivehydraulic distributor with a new one. Economically this option is 2-2.5 times (or 50-70%) more expensive than to perform a diagnostic (modern flow and pressure measurement equipment facilitates the determination of the failure cause), to repair (replacing thehydraulic distributor defective parts with original factory parts) and solve the problem. Factoring in quality and time spent, the latter option is more optimal for the benefit of the organization.
For example, a new hydraulic distributor costs € 5,000. The time lost ordering and with shipping and handling varies from 2 to 4 weeks. Repairing a hydraulic distributor will cost about 50% less, (costing – € 2500 or less) with a maintenance period of up to only 10 days. During repairs all defective parts (sliders, valves, springs and other elements) are replaced by new, original factory parts. No refurbished parts are used. After repairing yourhydraulic distributor, a control test is performed with the help of special hydraulic equipment; the technical parameters are readjusted so as to be in accord with the manufacturer’s requirements.
The restored hydraulic valve length of performance is equal to purchasing a new valve, as long as strict compliance is maintained to the manufacturer’s operating requirements.
