Honeywell Small Linear Thermoelectric Actuator with Indicator MT4-230-NC
The Honeywell MT4-230-NC Small Linear Thermoelectric Actuator offers precise and reliable operation for valves used in room and zone heating applications. Designed for noiseless, long-term performance, this compact actuator is perfect for controlling heating and cooling valves in fan coil units, radiators, floor heating systems, and manifolds.
Key Features
- Model MT4-230-NC – Normally closed actuator compatible with 230V mains supply.
- Visual position indicator – Red indicator behind the face window shows valve position and type of action (NO or NC) for easy monitoring.
- Noiseless operation – Silent performance suitable for residential and commercial environments.
- Reliable long-term operation – Robust construction ensures durability and consistent function.
- Compact design – Ideal for installation in limited space and on standard M30 x 1.5 valve fittings.
- Plug-in cable – Simplifies wiring and servicing with easy installation and maintenance.
- Water-protected housing – IP44 rated for protection in all mounting positions, suitable for heating system environments.
- Overload protection – 4 kV surge protection on 230V models for enhanced electrical safety.
- Operation modes – Supports two-position (on/off) or pulse width modulation (PWM) control for flexible heating and cooling modulation.
- Snap-on valve adapter – Tool-free mounting for fast and secure installation on thermostatic radiator valves and valve inserts.
