Proportional Valves - Requirements and Demands

Proportional valves is a comprehensive term.

We shall here exclusively deal with the load independent proportional directional valves, applicable on mobile, maritime and stationary equipment.

Proportional directional valves are used when it is required to improve a given machine or system in relation to one or more of the following eight items:

• -
  Increased Operator Comfort
• -
  Inproved Productivity
• -
  Greater Safety
• -
  Reduced Energy Consumption
• -
  Higher Flexibility
• -
  Lower System Price
• -
  Better Control Properties
• -
  Higher Degree of Automation

The very great and obvious advantage by using the aforementioned valves will be the posibility of remote control of the manoeuvring, e.g. electrically.

The paper will discuss the above mentioned items in detail.
