Software stepping

How It Works
Software stepping simulates a stepping actuator by controlling the valve's movement through a software algorithm. Instead of moving in one continuous motion, the valve takes small steps with pauses in between. This method allows for very fine control over how fast or slow the valve operates.

Applications

• Double acting actuators
• Spring return actuators

Benefits

• Provides precise control for applications requiring gradual flow adjustments.
• Reduces system wear by minimizing sudden valve movements.
• Allows custom fail-safe actions for loss of control or position signals.
• The amount of steps and hold time can be user configured.

Hardware stepping

How It Works
Mechanical stepping uses hardware settings to control the valve’s movement in defined steps. This method doesn’t rely on software but instead uses specific time intervals for opening and closing.

Applications

• Stepping actuators

Benefits

• Enables easy performance optimization through straightforward time interval adjustments.
• Supports configurable fail-safe actions in case of control system failures.
