Block integrated hydraulic system is the most ordinary kind integrated. It is the

hydraulic valve in hexahedral manifold, the set

Into blocks on the one hand mounting plate effect, on the other hand from th e hydraulic fittings suppliers

internal oil channel role, therefore the manifold block, also known as the manifold

block or channel block. Set

Into blocks is usually the basic circuit of a typical hydraulic system, do universal

cube or cuboid, as shown in Figure 4-14, the four

Week fittings in addition to side leading to the hydraulic actuators (hydraulic

cylinders, hydraulic motors or swing hydraulic motor) installed and the remaining

three surface mounting

Standard plate hydraulic valve and a small amount of stack valves, cartridge valves, hydraulic hose fitting

oil contact between the hydraulic valve manifold block internal channel pore

Block up and down both sides of the laminated block between the joint surface, cloth

from the bottom up through the channel body, pub lic pressure hole P back hole of O

(T)

Leak hole L and block connection bolt holes, multiple circuit blocks laminated

together by four bolts between the blockquick coupling fittings

Oil contact to achieve through a common hole.
1 block integration advantages
(1) simplify the design
(2) designed with the flexibility to change convenience
(3) ease of processing, high degree of specialization
(4) The compact structure, convenient maintenance and assembly
(5) The system is running more efficient
(2) block integration shortcomings
Manifold (1) design and machining of holes and error-prone, and requires a certain

design and manufacturing experience.
(2) the system is running, fault diagnosis is more difficult
