MVR230MC2

On-off electrothermal actuator for radiant system manifolds, 110...230 Vac power supply, complete with cable. Stem travel range: 11.3-12.4 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, overcoming the opposing spring and 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 unpowered.
