Product Information
Full details
The Danfoss HS3B28 is a 3-port paddle valve designed for efficient flow control in heating systems, offering 100% tight shut-off. It's ideal for plumbers and HVAC technicians working with copper or iron pipework, providing reliable diverter or on/off functionality. A potential consideration is that valve bodies and actuators are sold separately, requiring on-site assembly.

FAQs
What is the primary function of a 3-port valve?
A 3-port valve is used to control the flow of water in a heating system, typically to either divert flow between two different circuits or to shut off flow completely to one circuit.
Can I use this valve with any type of pipework?
The Danfoss HS3B28 valve is specifically designed for 28mm copper and iron pipework.
Do I need to buy the actuator and valve body separately?
Yes, valve bodies and actuators can be purchased separately or as convenient sets. Ensure you select the correct actuator for your needs.
What does '100% tight shut-off' mean?
It means that when the valve is in the closed position, it completely stops the flow of water, preventing any leakage or circulation.
How is the actuator attached to the valve body?
The actuator is assembled onto the valve body on-site using the screws provided.
What is the weight of the valve?
The weight of the valve body is 2.2 pounds.
Troubleshooting
Valve is not shutting off completely (leaking)
Check for debris caught in the valve seat. Ensure the actuator is correctly aligned and fully engaging the valve stem. Verify system pressure is within operating limits.
Actuator not moving the valve
Confirm the actuator is correctly fitted to the valve body. Check electrical connections to the actuator if it's an electric model. Ensure the valve stem is not seized.
Noisy operation
Investigate potential water hammer or restricted flow. Ensure the valve is installed in the correct orientation as per manufacturer instructions. Check system water flow rates.

Setup, Compatibility & Care
Setup: The Danfoss HS3B28 valve requires on-site assembly of the actuator to the valve body using the provided screws. Ensure the correct actuator type (mid-position, diverter, or 2-port on/off) is selected for your application.
Compatibility: This valve is designed for use with 28mm copper and iron pipework. It is compatible with Danfoss actuators from the H-series range.
Care: Regular maintenance is recommended for optimal performance. Ensure the valve is free from external debris. For internal components, refer to Danfoss service documentation. Do not attempt to service the internal parts unless qualified, as this may void the warranty. Ensure system water is clean to prevent debris from interfering with the valve's operation.
