1) valve block all the oil flow path, especially with the hole through the intersection is empty, must be careful to clean burr, light stretching with the probe into the hole carefully cleared checks. Ported peripheral edges must be chamfered each week deburring. Finished processing of the hydraulic system and the hydraulic valve block valves, fittings, flanges bonded phase plane may be left scars, nor crossed left traces. 2) Hydraulic system valve block after processing must be repeated with pressurized cleaning liquid rust cleaning. The holes flow channel, especially for blind holes should pay particular attention wash. Cleaning tank should be divided rough cleaning and fine cleaning. After cleaning the valve blocks, such as temporarily assembled, immediately cover each orifice, can be substantial on tape sealing the orifice. 3) to the valve block mounted hydraulic valve hydraulic system, to check their models, specifications. The valves must have product certification, and confirmed its cleanliness qualified. 4) Check all hydraulic system seals specifications, models, materials and manufacture date (period should be used). 5) Check the valve again before assembly on the block all the pores are consistent with the design and correct. 6) Check the bolts used in the material and strength to meet the design requirements and hydraulic parts manufacturing plant requirements. Hydraulic system valve on the hydraulic valve block connecting bolts must be tightened with a wrench dynamometer. Tightening torque hydraulic valve manufacturer shall comply with the requirements. 7) Where a locating pin hydraulic system valves must be fitted with locating pins. 8) valve block should be set on a small metal plate, indicating the valve in the hydraulic system design on the serial number, the name of each loop, the role of the external interfaces. 9) hydraulic system valve block assembly is completed, the shelf or mounted to the valve on the hydraulic system before, you should first conduct a separate manifold pressure test and functional test.
