Control the water flow in your heating and hot-water circuits accurately with the Flume three-port actuator. Engineered for domestic and light-commercial systems, it provides dependable regulation across demanding environments.

The robust housing contains high-quality components designed for continuous daily use. A high-torque synchronous motor ensures stable valve positioning, while the spring-loaded manual lever lets you lock the valve open during system filling and maintenance.

Fit the actuator effortlessly using the user-friendly screw-fix mounting system, which requires no system draining. It communicates dependably with standard UK and European heating controls to activate the boiler or pump as needed.

• High-torque motor – provides stable and precise valve positioning
• Screw-fix mounting – allows quick fitting without draining the system
• Spring-loaded manual lever – simplifies filling and maintenance tasks
• Durable construction – resists mechanical wear during continuous operation
• Universal compatibility – integrates easily with standard three-port valves
