    Manifold Hydraulic Valve Block Hydraulic Motor Cushion Valve For Rotary Excavator
    The design of hydraulic valve block is mostly non-standard design, which needs to be conducted according to different working conditions and use requirements
    The design of valve block is divided into the following steps: material selection, design, processing and heat treatment, deburring and
    Cleaning, surface anti-rust treatment and test.

    Different materials determine different pressure levels. First, select materials reasonably according to the service pressure. Generally
    The following principles shall be followed:
    When the working pressure P<6.3MPa, the hydraulic valve block can be cast iron HT20-40. Cast iron can be used
    In order to carry out mass casting, reduce working hours and improve efficiency, especially suitable for standardized valve blocks.
    When 6.3MPa ≤ P<21MPa, the hydraulic valve block can be aluminum alloy forgings, No. 20 forged steel or Q235;
    Low carbon steel has good welding performance, especially suitable for non-standard hard pipes (many valve blocks need to be welded with hard pipes in use
    Connect).
    When P ≥ 21MPa, the hydraulic valve block can be made of 35 # forged steel. Direct machining or machining after forging
    Post quenching and tempering HB200-240 (general high-pressure valve blocks are often subject to flaw detection, machining and heat treatment cycles.
