2-Position Valve Actuator

R2026b

This example demonstrates the Multiposition Valve Actuator block with two positions. The same signal controls two valve actuators, but the actuators use different values of the Switching-on time, Switching-off time, and Initial position parameters.

Model

Simulation Results from Scopes

These plots show the behaviors of the two valve actuators. When the time is 2 seconds, a pulse about 1 second long applies to both actuators. The values of the Initial position parameter of the Valve Actuator 1 and 2 are Retracted and Extended, respectively. Actuator 2 shifts to the neutral position in the initial period before the pulse applies. Each actuator position reaches the push-pin stroke upon receiving the pulse, and the duration of each extension is the specified switching-on time. When the signal value reduces to zero, the position returns to zero over the specified switching-off time.
