MT8-230S-NO open actuator, 90 N, 230 Vac, stroke 8 mm, cable length 1m

Small linear thermoelectric actuators are used in room and zone applications for time-controlled two-point and pulsewidth modulated (PWM) regulation of heating and cooling systems such as fan coil units, radiators, floor heating systems, chilled ceilings, manifolds and convectors.

• Fit on standard M30 x 1.5 heating/cooling valves, thermostatic radiator valves, and valve inserts for manifolds and compact radiators
• Fit to standard closing dimensions (11.5 mm +- 0.3 mm)
• Special valve adapters on request
• Variants available for closing dimensions 11.5 mm (+- 0.3 mm) or 11.0 (+- 0.3 mm)
• No mounting tools required (easily mounted using valve adapter)
• Water-protected housing design in all mounting positions
• Pluggable cable for easy installation and servicing
• Auxiliary switch models for driving pumps or fans
• Compact design allows installation in limited space
• Visual indicator showing valve position and type of action (NO or NC)
• Noiseless operation
• Reliable long-term operation
• Overload protection (4 kV) for 230 V models
