Notes on the block.

We write down the questions we come across most often in design, manufacturing and valve selection.

ALL ARTICLES

Eight topics
in all.

Technical notes on hydraulic manifold design, manufacturing and valve selection. Seven articles published, one in preparation.

3D model of a hydraulic manifold blockTECHNICAL

What is a hydraulic manifold block and where is it used?

What a manifold block does, in which applications it is preferred and how it differs from conventional piping.

Hydraulic block fitted with numerous cartridge valvesTECHNICAL

What to consider when selecting a cartridge valve

Flow rate, working pressure, control type and cavity standard: the four headings that decide valve selection.

Top view of a black hydraulic block with machined portsTECHNICAL

Cavity and port layout in hydraulic block design

How port layout and cavity positioning affect assembly, maintenance and pressure loss.

Manifold plates with drilling completedTECHNICAL

Tolerance and surface finish in NC drilling

What machining tolerance means and why it is decisive on sealing surfaces.

Machined steel hydraulic blockTECHNICAL

Hydraulic block material: aluminium or steel?

Choosing the material according to the balance between working pressure, weight and cost.

Long black manifold block with many portsTECHNICAL

Design decisions that reduce pressure loss inside the block

The effect of passage diameter, intersection angle and dead volumes on system efficiency.

Re-manufactured hydraulic blocksTECHNICAL

OEM-equivalent block production for construction machinery spares

How an equivalent is produced by measuring the existing block when no drawing is available.

Fully assembled hydraulic blocksIN PREPARATION
