MVR230M

On-off electrothermal actuator for radiant system manifolds, 110...230 Vac power supply, complete with cable. Spindle extension range: 10.7-11.8 mm. The control signal powers the servo control. The presence of the control signal causes a thermostatic element to heat up, leading to the extension of a piston. This piston 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.
