1. Producte acabatview
The Belimo Z215S-230 is a compact, motorised 2-way zone valve designed for precise control in heating, ventilation, and air conditioning (HVAC) systems. It is suitable for both open and closed cold and warm water systems, commonly found in fan coil units and VAV (Variable Air Volume) boxes. This valve is de-energised closed (NC), meaning it returns to a closed position when power is removed.

2. Informació de seguretat
Please read all safety instructions carefully before installation, operation, or maintenance of the Belimo Z215S-230 valve. Failure to comply with these instructions may result in property damage, injury, or death.
- La instal·lació i el manteniment només els ha de dur a terme personal qualificat.
- Disconnect power supply before performing any wiring or maintenance.
- Ensure the valve is installed in an environment within its specified operating temperature and pressure limits.
- Do not expose the valve to corrosive substances or extreme vibrations.
- Comproveu el vol correctetage and wiring connections as per the product label and wiring diagram.
3. Instal·lació
Llista de comprovació prèvia a la instal·lació:
- Ensure the valve size (15mm) matches the piping system.
- Verify the system pressure and temperature are within the valve's specifications.
- Confirm the power supply (230V AC, 50/60Hz) is available and matches the actuator requirements.
- Have appropriate tools for installation (wrenches, wire strippers, etc.).
Instruccions de muntatge:
- Flush the piping system thoroughly to remove any debris before installing the valve.
- Install the valve in a location that allows for easy access for wiring, maintenance, and manual override (if applicable).
- Ensure the flow direction arrow on the valve body aligns with the system's fluid flow.
- Thread the valve into the piping system, ensuring a tight, leak-free connection. Use appropriate thread sealant if necessary.
- Do not apply excessive torque to the actuator housing during installation; tighten only the valve body.
Connexions de cablejat:
The Belimo Z215S-230 valve requires a 230V AC power supply. Refer to the wiring diagram on the actuator label for precise connections. Typically, these valves have two wires for power (Live and Neutral) and may have an additional wire for control signal depending on the specific model variant. Ensure all connections are secure and insulated.
- Connect the Live (L) wire to the designated terminal.
- Connect the Neutral (N) wire to the designated terminal.
- Ensure proper grounding if a ground terminal is present.
- Verify all wiring against local electrical codes and standards.
4. Funcionament
The Belimo Z215S-230 is a motorised valve designed for automatic operation based on a control signal (e.g., from a thermostat or building management system). As a de-energised closed (NC) valve, it will remain closed when no power is supplied to the actuator.
Funcionament bàsic:
- Once correctly installed and wired, apply power to the actuator.
- Upon receiving a control signal (e.g., a call for heating/cooling), the actuator will energise and open the valve, allowing fluid flow.
- When the control signal is removed or power is cut, the actuator will de-energise, and the valve will return to its closed position.
- Observe the flow indicator (if present) or listen for fluid movement to confirm valve operation.
5. Manteniment
The Belimo Z215S-230 valve is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance.
Manteniment rutinari:
- Inspecció visual: Periodically inspect the valve and actuator for any signs of leaks, corrosion, or physical damage.
- Comprovació de la connexió: Assegureu-vos que totes les connexions elèctriques estiguin ben fixades i lliures de corrosió.
- Comprovació operativa: Cycle the valve manually or via the control system to confirm smooth opening and closing.
- Neteja: Keep the exterior of the actuator free from dust and debris.
No internal lubrication or disassembly of the actuator is required or recommended. If the valve or actuator malfunctions, it should be replaced by a qualified technician.
