Description
Description
MUT SF-2 — 2-Way Motorized Zone Valve with Spring Return | Normally Closed
The MUT SF-2 series zone valve is a 2-way motorized valve with a ball valve and spring return, designed for controlling hot and cold water flow in heating and cooling systems. The valve is normally closed (NC): in the absence of electrical power, the spring return automatically returns the ball valve to the closed position, ensuring system safety in the event of a power outage. Available in 3/4" F/F (code 7.001.01603) and 1" F/F (code 7.001.01639) versions, with the option of equipping the motor head with an auxiliary microswitch.
- Series: SF-2
- Type: 2-way motorized zone valve
- Valve: Ball valve (fully open / fully closed)
- Rest position: Normally closed (NC)
- Return: Spring return (fail-safe)
- 3/4" version: Code 7.001.01603 — EAN 8054701820094
- 1" version: Code 7.001.01639 — EAN 8054701820117
- Connections: F/F (female/female)

- Made in Italy: Yes
Main features
- On/off ball valve — fully open / fully closed operation; ideal for zone shut-off applications where flow modulation is not required. Ensures a perfect seal in the closed position and minimal pressure drop in the open position.
- Spring return (fail-safe NC) — in the event of a power outage, the spring automatically returns the valve to the normally closed position, protecting the system from overheating or flooding.
- Motor head with or without auxiliary microswitch — the auxiliary microswitch signals the valve's open state to the control unit, allowing the circulation pump to start only when the valve is actually open (end-switch function).
- External lever for manual positioning — allows the valve to be manually positioned in the center for maintenance operations or system testing without the need for electrical power.
- Available in 3/4" and 1" F/F — two versions to suit the most common pipe diameters in residential and commercial heating and cooling systems.
- Made in Italy — MUT quality — manufactured in Italy with professional-grade materials and workmanship; MUT is a leading name in the Italian hydronic heating sector.

Frequently Asked Questions (FAQ)
Q: What does "normally closed" (NC) mean?
A: A normally closed valve is in the closed position when it is not electrically powered. When the control unit or thermostat sends the opening signal, the motor opens the valve; when the signal ceases, the spring automatically returns the valve to the closed position. This ensures system safety in the event of a power outage.
Q: How do I choose between the 3/4" and 1" versions?
A: The choice depends on the pipe diameter of the hydronic circuit where the valve will be installed. The 3/4" version (code 7.001.01603) is suitable for 3/4" pipes, while the 1" version (code 7.001.01639) is suitable for 1" pipes. Check the diameter of the existing pipes before purchasing.
Q: What is the auxiliary microswitch and when is it needed?
A: The auxiliary microswitch is an electrical contact that closes when the valve reaches the fully open position. It is used to signal to the zone control unit or thermostat that the valve is open, allowing the circulation pump to start only when at least one zone is active. It is required when the control unit needs the end-switch signal for pump management.
Q: Is the SF-2 valve compatible with heat pump systems?
A: Yes. The SF-2 valve is suitable for air-to-water heat pump systems and hybrid systems, for both heating and cooling zone management, provided that the technical characteristics (pressure, temperature, fluid) are compatible with the specifications indicated in the technical data sheet.
