About Motorized Spring Return Zone Valves

MAIN CHARACTERISTICS : These are powered by an electric motor and can assume two operating positions depending on whether or not the motor is activated. One two auxiliary switches can be installed and be actuated when the valve switches. Valves are equipped with a three-way SF valves. They are designed to make the connection system to plumbing pipelines more versatile. When a special flange is mounted on these valves they can be equipped with the most suitable system of connections. Various types of flanges are available and can be preassembled with the valve. These cover practically the entire range of the type of the types of connections currently in use. The flange system can also simplify, in particular cases, disconnection of the valve body form the pipeline system.

OPERATION: When it is without electricity the valve is positioned as in fig.1: the valve is closed. When the electrical supply is activated the motor overcomes the force of the spring and moves the bell form way A to an intermediate position in the two-way versions or closes way B in the 3-way version (fig.2). The shut- off ball remains in this position until the electrical power supply is deactivated. When the electrical power supply is deactivated the return spring brings the shut-off ball back to way A.

USING THE MANUAL LEVER: A lever is position next to the servomotor that permits manual positioning of the shut-off ball in an inter- mediate position (fig.3). This is useful when filling or emptying the hydraulic system. The lever reset, form manual to automatic, takes place automatically whenever the valve is activated by electricity.

AUXILIARY SWITCHES: A single pole micro switch (M1 version with C-NO connection), a two-pole micro switch (M1 version) or two micro switches (M2 or M2S version) can be mounted on all versions. There is a Special kit for mounting the auxiliary single-pole micro switch even in versions that do not carry it is an original part (M1 Kit). M1S kits, M2 or M2S cannot be installed on versions which do not mount them originally.

APPLICATION EXAMPLE .1) INSTALLATION OF THE TWO-WAY ZONE VALVE This is the typical zone installation. It requires SF valves with travel limit micro switch to stop the pump when they are all closed. Other standard market components are also necessary such as valves with a differential by-pass to prevent bothersome noise and to keep pump pressure constant.

INSTALLATION OF THE THREE -WAY ZONE VALVE This is the most up-to date installation. It uses the recirculation path, duly regulated by a gate valve, to obtain good room temperature adjustments. It is also easy to install a clock to be able to subdivide operating costs.

Reliable Zone Control for HVAC Systems

Our motorized spring return zone valves are designed to streamline zone control in heating and cooling applications. With precise on/off regulation and rapid 15-second actuation, these valves are perfect for efficient energy management in large-scale or multi-zone HVAC networks. The robust brass body and stainless steel or brass stem construction ensure reliable operation under pressure (up to 10 Bar) and temperature ranges suitable for both water and glycol solutions.

Easy Installation and Operation

Installation is straightforward with options for horizontal or vertical mounting. The quick connection feature minimizes downtime, while the integrated manual override and visual position indicator provide enhanced user control and monitoring. Operate the valves using either two-pin or three-pin wiring, supporting 220V AC or 24V AC power supplies to suit various system designs.

FAQs of Motorized Spring Return Zone Valves :

Q: How are these motorized spring return zone valves typically installed for optimal performance?

A: For best results, the valve should be mounted horizontally, although a vertical position is also allowed. The quick connection system simplifies installation, and the valve can be integrated into most HVAC, heating, and cooling pipelines. Always ensure the power supply and wiring (2 or 3 pin) match your systems requirements.

Q: What advantages does the spring return actuator offer in HVAC applications?

A: The spring return actuator automatically returns the valve to its default position during power loss or system failure, enhancing safety and system reliability. This feature ensures immediate shut-off or reopening as needed without manual intervention, supporting uninterrupted operation during critical scenarios.

Q: When should manual override and visual indicators be used?

A: The manual override is essential during maintenance or in the event of actuator failure, allowing you to operate the valve manually. The visual position indicator helps confirm the valves current open or closed status at a glance, improving system monitoring and troubleshooting efficiency.

Q: Where can these valves be utilized within a facility?

A: These motorized zone valves are ideal for zoning control in hot or cold water circuits, glycol solutions, and steam pipelines used in commercial, industrial, and residential HVAC systems. They are suitable for use in boilers, fan coil units, radiant panels, and central chilled/heated water distribution systems.

Q: What is the process for connecting the valve to a building management system (BMS)?

A: Each valve is compatible with common thermostat and BMS protocols. The wiring (2 or 3 pin) should be connected according to your systems power specifications (220V AC or 24V AC). Once installed, the BMS can communicate directly with the actuator for precise zone control.

Q: How does the low noise level benefit end users in sensitive environments?

A: With an operating noise level below 40 dB(A) at one meter, these valves minimize disturbance, making them particularly suitable for offices, hospitals, libraries, and residential installations where quiet operation is essential.

Q: What is the expected service life and maintenance requirement for these valves?

A: Designed for a service life of at least 100,000 operations, these valves offer long-term reliability with minimal maintenance. Periodic inspections are recommended to ensure proper actuator function and seal integrity, especially in demanding environments.
