MVR24MC1

On-off or PWM (proportional time pulses) electrothermal actuator for radiant system manifolds, 24 Vac power supply, complete with cable. Stem travel range: 12.3-13.4 mm. The control signal powers the servo control. The presence of the control signal causes a thermostatic element to heat up, and a piston to extend as a result. This overcomes the opposing spring, allowing the manifold valve stem to lift. This model is equipped with an auxiliary contact. The microswitch has an open contact when the servo control is de-energized.
