MVR230MC1

On-off electrothermal actuator for radiant system manifolds, 110...230 Vac power supply, complete with cable. Stem output 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 the consequent extension of a plunger which, overcoming the opposing spring, allows 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.
