1. Characteristics of pressure compensation

2. Characteristics of anti-saturation function

When supply flow is sufficient:

When supply flow is insufficient:

• Same secondary pressure is supplied to every compensator
• Supply flow for all actuators is distributed in proportion to spool stroke.

3. Interconnected control stroke for engine rotation speed - Characteristics of flow

Normal load sensing system

Cooperative system with engine speed

• Target LS differential pressure is cooperative with engine speed
• Much finer control with gentle gain between stroke and flow rate.
