Common Types of Valve Flow Characteristics

Each strong textvalve has a flow characteristic, which describes the relationship between the flow rate and valve travel.

As a valve opens, the flow characteristic, which is inherent to the design of the selected valve, allows a certain amount of flow through the valve at a particular percentage of the stroke.

This enables flow regulation through the valve in a predictable manner.

The three most common types of flow characteristics are:

  1. Linear

  2. Equal percentage

  3. Quick opening
