Description
Description
MUT SF-2 Motorized 2-Way Zone Valve — Micro Switch + Spring Return | 5-Wire | Normally Closed | 3/4'' or 1'' F/F
The MUT SF-2 2-Way Motorized Zone Valve is a motorized shut-off valve with an auxiliary micro switch and spring return, designed for controlling hot and cold water flow in heating and cooling systems. The ball valve operates in fully open / fully closed mode, with a normally closed rest position ensured by the spring return. The 5-wire connection includes the auxiliary micro switch, which signals the valve's switching and enables integration with control and automation systems. Available in 3/4'' F/F (SF 20-2 M1) and 1'' F/F (SF 25-2 M1) versions.
- Type: Motorized 2-way zone valve
- Actuator: Ball — fully open / fully closed
- Rest position: Normally closed (NC)
- Return: Spring return
- Auxiliary micro switch: Yes — 5 wires
- Available versions: SF 20-2 M1 (3/4'' F/F) — SF 25-2 M1 (1'' F/F)
- Application: Heating and cooling systems
Main Features
- 2-way shut-off valve: Designed to control flow in two-way hydraulic circuits, it allows the fluid flow to be fully opened or closed in response to the electrical signal from the thermostat or control system.
- Fully open / fully closed ball actuator: On/off operation ensures maximum reliability and a long actuator lifespan, eliminating the typical problems associated with proportional control valves.
- Normally closed with spring return: In the absence of electrical power, the spring automatically returns the valve to the closed position, ensuring system safety in the event of a power outage.
- Auxiliary micro switch (5 wires): The micro switch integrated into the motor head activates during valve switching, providing a feedback signal to the control system to confirm that the valve has actually opened.
- Manual positioning lever: The external lever allows the actuator to be manually positioned in the center, which is useful for maintenance operations or in the event of motor failure.
- 3/4'' and 1'' F/F versions: Available with two female/female threaded connections to adapt to different pipe sizes in hydraulic systems.
- Universal heating/cooling application: Suitable for controlling circuits with hot water (heating) and cold water (cooling), and compatible with major thermal control systems.

Application Areas
- Zoned heating systems: Control of hot water flow in zoned heating circuits, allowing the temperature of each zone in the system to be managed independently.
- Cooling systems: Control of cold water flow in air conditioning and fan coil systems.
- Radiant floor heating systems: Shut-off for underfloor heating circuits in combination with manifolds and zonal control systems.
- Heat pump systems: Control of hydraulic circuits in heat pump systems for heating and cooling.
- Home automation and control systems: Integration with centralized control systems thanks to the auxiliary micro switch, which provides feedback on the valve opening.

Frequently Asked Questions (FAQ)
Q: What is the difference between the micro (5-wire) and non-micro (3-wire) versions?
A: The micro switch version (5 wires) provides a feedback signal to the control system, confirming that the valve has actually opened. The non-micro version (3 wires) does not have this return signal. The micro version is required when the control system needs to know if the valve is actually open before starting the pump.
Q: What does “normally closed” mean?
A: It means that in the absence of electrical power, the spring automatically returns the valve to the closed position. When the electrical signal arrives (e.g. from the thermostat), the motor opens the valve against the force of the spring. When the signal ceases, the spring automatically closes the valve.
Q: How do I choose between the 3/4'' and 1'' versions?
A: The choice depends on the diameter of the system's pipes. The SF 20-2 M1 (3/4'') version is suitable for 3/4-inch pipes, while the SF 25-2 M1 (1'') is for 1-inch pipes. Check the diameter of the system's fittings before purchasing.
Q: Can I operate the valve manually in the event of a failure?
A: Yes, the valve is equipped with an external lever for manually positioning the actuator in the center, which is useful for maintenance or emergency operations.
