Things You Will Learn
Learn about the different strategies used to design hydraulic systems. This section will help you understand why specific types of hydraulic equipment are used.
HS01 - Industrial CETOP sandwich, manifold or cartridge design strategies
This module discusses some common industrial design techniques including sandwich plate design, platen/manifold mounted design or cartridge design. We cover the history and reasons behind why these techniques have become so widely used along with discussing the types of application where they would be used. Topics covered are:
- Industrial sandwich, manifold or cartridge design strategies
- Background to industrial hydraulic system design
- Line mounted valves
- Sandwich plate mounted valves
- Manifold or platen mounted designs
HS02 - Mobile design strategy
This module discusses the mobile, mono-block approach to system design. We cover the history and reasons behind why these techniques have become so widely used along with discussing the types of application where they would be used.
- Basic mobile 6-way valve
- Open centre mobile valve designs
- Closed centre mobile valve designs
- Pressure compensation
- Pre and post-compensated valves
- Load sensing signal
- Reducing and relief valves
- Mono-block end plates
HS03 - Cartridge design strategy
This module discusses the cartridge design approach for hydraulic system design. We cover the advantages and potential issues from using this technique as well as discussing typical application where it may be used.
- What cartridge valves are used for?
- How cartridge valve designs work
- Different types of cartridge valve
- Tips and tricks for maintaining cartridge valve system
- How to specify hydraulic cartridge valves

HS05 - Load control strategies
This module discusses the different types of load control system and explains some of the key points to be aware of. Topics covered are:
- Operator Safety
- Load Control Fundamentals
- Counterbalance valve and PO check Features
- Application Advice
- Problems and Solutions.
HS06 - Proportional control strategies
This module discusses the different types of proportional control and explains some of the key points to be aware of. Topics covered are:
- Flow control methods
