Three-way zone diverter valve with actuator Samee TO3SQM25 DN20 (G1")

The Three-way zone diverter valve Samee TO3SQM25 DN20 (G1") is a motorized valve with integrated actuator designed for hydraulic zone control and flow switching in heating, cooling or mixing circuits. Compact and engineered for residential and light-commercial HVAC systems, the valve redirects fluid between two outlets to regulate distribution from a single supply line. The DN20 (G1") connection size fits common pipework and the built-in actuator provides automated control without the need for a separate drive unit.

Advantages

The integrated actuator simplifies installation and reduces the number of separate components required for zone control. The valve body and sealing materials are selected to ensure reliable operation in closed-loop HVAC systems, while the three-way configuration allows flexible routing for heating, cooling or bypass applications. Motorized operation enables precise switching and reduces the need for manual intervention, improving system responsiveness and integration with thermostatic or automated controls.

Suitable for

• Hydronic heating zone control in residential buildings
• Mixing circuits for temperature regulation in radiator or underfloor heating systems
• Cooling distribution and chiller-side switching in small commercial systems
• Boiler and heat-pump installations requiring motorized flow diversion
• Bypass or divert applications to maintain minimum flow or prevent overheating

Key specifications

• Valve type: three-way diverter valve with integrated actuator
• Nominal diameter: DN20 (G1")
• Connection: threaded G1" pipe connection
• Actuation: electric motorized actuator integrated into valve body
• Application: suitable for heating, cooling and mixing circuits
• Material characteristics: corrosion-resistant valve body and compatible sealing materials for HVAC fluids
• Mounting orientation: suitable for typical horizontal or vertical piping arrangements (follow installation instructions)

How to use

Install the Three-way zone diverter valve in-line with the piping according to the system design, ensuring correct orientation of inlet and outlet ports. Connect the valve to the electrical control signals specified by the actuator manufacturer and integrate with the system thermostat or controller. Commission the valve by performing an initial cycle to confirm smooth transition between ports and to check for leaks. Adjust system controls so the valve operates in response to zone demand, temperature setpoints or automated schedules.
