MVR230MC3

On-off electrothermal actuator for radiant system manifolds, 110...230 Vac power supply, complete with cable. Stem travel range: 10.3-11.4 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 move out, which, by overcoming a return spring, allows the manifold valve stem to rise. This model is equipped with an auxiliary contact. The microswitch has an open contact when the servo control is de-energized.
