What it is

The Honeywell MT8-230-NO is a thermal actuator with an 8mm connection, rated for a 230V supply. It operates as a normally open (NO) device, so the valve it controls is open until the actuator is powered. Honeywell lists it within their thermal actuator range for controlling valves in heating circuits.

Before you order

  • Confirm the valve body has an 8mm connection to match the actuator.
  • Check that a 230V supply is available at the point of installation.
  • Confirm that normally open operation suits the circuit's requirements.
  • Verify the part number MT8-230-NO against the existing actuator.
