2. Bezpečnostní informace
VAROVÁNÍ: Nedodržení těchto bezpečnostních pokynů může vést k poškození majetku, vážnému zranění nebo smrti.
- Ensure the power supply is disconnected before any installation, maintenance, or troubleshooting.
- Ověřte, že svtage and current ratings of your power source match the valve's requirements (9-24V AC/DC).
- Install the valve in an environment suitable for its IP65 rating, protecting it from dust and water jets.
- Do not exceed the maximum operating pressure of 10 Bars.
- Ensure proper threading (NPT) and secure connections to prevent leaks.
- This valve is designed for fluid control; do not use it for purposes other than its intended application.
3. Vlastnosti produktu
- Bezpečné a spolehlivé: Constructed from 304 stainless steel, ensuring durability and an estimated life expectancy of 80,000 to 100,000 cycles.
- NPT Threading: Features 1-inch quality 304SS NPT threads, designed to minimize pressure loss with its full port bore.
- Wide Voltage Rozsah: Operates effectively across a 9V-24V AC/DC range, opening or closing the valve in 3-5 seconds.
- 2-Wire Automatic Return Setup: Simple two-wire connection. The valve largely de-energizes after closing and returns to fully open if power is removed.
- Alternative to Solenoid Valves: Automatically cuts off power once fully open or fully closed, reducing the likelihood of overheating.

5.3. Electrical Wiring (2-Wire Auto Return)
The 2-wire auto return motorized ball valve is designed for simple electrical connection. It operates by energizing one wire to open the valve and de-energizing it to allow the valve to return to its default (open or closed) position. For this model, the valve is normally open and closes when power is applied.

Refer to the wiring diagram below for correct connections:

Figure 3: 2-Wire Auto Return Wiring Diagram for DC and AC power sources.
- Connect the red wire to the positive (+) terminal of your power source.
- Connect the green wire to the negative (-) terminal of your power source.
- When power is applied, the valve will close. When power is removed, the valve will automatically return to its fully open position.
6. Návod k obsluze
6.1. Základní obsluha
This motorized ball valve operates on a simple 2-wire auto-return principle. The valve's default state is normally open. When electrical power (9-24V AC/DC) is supplied to the red and green wires, the internal motor activates, rotating the ball to the closed position. Once the valve is fully closed, a limit switch minimizes power consumption. When the power supply is interrupted or removed, the valve automatically returns to its fully open position.
- Zavření ventilu: Apply 9-24V AC/DC power to the red (positive) and green (negative) wires. The valve will rotate to the closed position in approximately 3-5 seconds.
- Otevření ventilu: Remove the power supply from the red and green wires. The valve will automatically rotate back to the fully open position.
7. Údržba
Regular maintenance ensures the longevity and optimal performance of your motorized ball valve.
- Pravidelná prohlídka: Regularly check the valve and connections for any signs of leaks, corrosion, or physical damage.
- Čištění: Keep the exterior of the valve and actuator clean and free from debris. Use a soft, damp hadřík na čištění. Nepoužívejte abrazivní čisticí prostředky nebo rozpouštědla.
- Elektrické připojení: Periodically inspect electrical wiring for secure connections and insulation integrity.
- Skladování: If storing the valve for an extended period, ensure it is clean, dry, and stored in a temperate environment.
8. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Ventil se neotevírá/nezavírá | Žádné napájení nebo nesprávné zapojení. | Check power supply and verify wiring according to Section 5.3. |
| Ventil se úplně neotevírá/nezavírá | Obstruction in the valve or low voltage. | Inspect the valve for debris. Ensure power supply is within 9-24V AC/DC range. |
| Únik z přípojek | Improperly sealed threads or loose connections. | Disconnect power, reapply thread sealant (Teflon tape), and tighten connections. |
| Ventil vydává neobvyklý zvuk | Internal mechanical issue or debris. | Disconnect power. If noise persists or operation is affected, contact customer support. |
