MVR230C2

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 the consequent extension of a piston, which, overcoming the opposing spring, allows the manifold valve stem to rise.
