MVR230C1

On-off electrothermal actuator for radiant system manifolds, 110...230 Vac power supply, complete with cable. Stem stroke range: 12.3-13.4 mm. The control signal constitutes the power supply for the servomechanism. The presence of the control signal causes the heating of a thermostatic element and the consequent extension of a piston which, overcoming the opposing spring, allows the stem of the manifold valve to rise.
