When you install a DCL 24V ON-OFF type electric control valve<\/strong> on a pipeline, you can control it using a relay, ON-OFF control, or PLC (DCS), enabling the opening or shutting off of fluid flow.<\/p>

This guide explains how the DCL 24V ON-OFF type electric actuators<\/strong> function using relays, PLCs, or ON-OFF control for valve operation.<\/p>

Using Relay\/PLC\/DCS to Control DCL Actuators<\/strong><\/h3>

<\/p>

  • When the relay switches the power (+) line to the “ON” input terminal<\/strong> and the power (-) line to the “OFF” input terminal<\/strong>, the actuator drives the valve open<\/strong>. Once fully open, the actuator stops, and the electric valve remains open<\/strong>.<\/p><\/li>

  • When the relay switches the power (+) line to the “OFF” input terminal<\/strong> and the power (-) line to the “ON” input terminal<\/strong>, the actuator drives the valve closed<\/strong>. Once fully closed, the actuator stops, and the electric valve remains closed<\/strong>.<\/p><\/li>

  • If power is lost while the actuator is in operation, the actuator stops driving<\/strong>, and the electric valve stays in its current position<\/strong>.<\/p><\/li>

  • If your actuator is equipped with a heater and dehumidifier<\/strong>, keep the power supply on<\/strong> after the actuator reaches the fully open or fully closed position.<\/p><\/li><\/ul>

    Note:<\/strong> The circuit diagram provided illustrates the basic function of an ON-OFF type actuator (electric valve). In practical applications, fuses, current limiters, and other protective components should be added<\/strong>.<\/p>
