1. Uvod i krajview
This manual provides essential information for the safe and effective installation, operation, and maintenance of your U.S. Solid 1/2" Brass Electric Solenoid Valve. This valve is designed for controlling the flow of air, water, oil, and fuel, featuring a normally closed configuration and a durable VITON gasket for chemical resistance.
Please read this manual thoroughly before installation and operation to ensure proper function and to prevent damage or injury.
2. Sigurnosne informacije
UPOZORENJE: Ovaj proizvod vas može izložiti hemikalijama, uključujući olovo, za koje je u državi Kaliforniji poznato da uzrokuje rak i urođene mane ili druge reproduktivne štete. Za više informacija posjetite www.P65Warnings.ca.gov.
- Always disconnect power before installing, servicing, or performing maintenance on the valve.
- Ensure the valve is compatible with the fluid or gas being controlled. The VITON gasket is suitable for gasoline, kerosene, and other organic solvents. Do NOT use NBR gaskets for gasoline.
- Install the valve in a location that is easily accessible for inspection and maintenance.
- Ensure proper electrical connections are made according to local codes and regulations.
- Avoid exceeding the maximum pressure and temperature ratings specified for the valve.
3. Značajke proizvoda
- 1/2" NPT (USA National Pipe Thread): Commonly used standard pipe thread in the U.S.
- Čvrsta mesingana konstrukcija: The valve's body is made of solid brass, offering excellent corrosion resistance.
- Unidirectional Flow: An arrow on the valve body indicates the intended flow direction. Horizontal mounting is recommended.
- Direct Acting and Normally Closed: The solenoid's magnetic field directly moves the plunger to close the orifice for fluid or gas flow. The valve only opens when energized.
- VITON Gasket: Viton is a chemically inert material, ideal for use with gasoline, kerosene, and other organic solvents.
- IP65 ocijenjeno: Pruža zaštitu od prodora prašine i mlazova vode niskog pritiska iz bilo kojeg smjera.

4. Postavljanje i instalacija
4.1 Mehanička instalacija
- Identify the inlet and outlet ports. The valve is unidirectional, and an arrow on the body indicates the flow direction.
- Apply appropriate thread sealant (e.g., PTFE tape) to the 1/2" NPT threads before connecting to piping.
- Mount the valve horizontally for optimal performance.
- Uvjerite se da su svi spojevi čvrsti kako biste spriječili curenje.

4.2 Električni priključak
The valve operates on 12V DC. Connect the power supply to the solenoid coil terminals. The polarity for DC operation typically does not matter for the coil itself, but ensure your power supply is correctly wired.
- Connect the positive (+) lead from your 12V DC power source to one terminal of the solenoid coil.
- Connect the negative (-) lead (ground) from your 12V DC power source to the other terminal of the solenoid coil.
- Osigurajte da su svi električni priključci sigurni i izolirani kako biste spriječili kratki spoj.
5. Uputstvo za upotrebu
This is a normally closed (NC) solenoid valve. This means that when no power is applied to the coil, the valve remains in a closed position, preventing fluid or gas flow. When 12V DC power is applied to the coil, the solenoid energizes, pulling the plunger and opening the valve to allow flow.
- To open the valve: Apply 12V DC power to the solenoid coil.
- To close the valve: Remove 12V DC power from the solenoid coil.
- The valve is designed for short cycles. For applications requiring continuous flow for extended periods (e.g., over 3 hours), consider using a motorized valve instead.
6. Održavanje
Regular inspection and maintenance can extend the lifespan of your solenoid valve.
- čišćenje: Periodically inspect the valve for debris or buildup, especially if used with fluids containing particulates. The valve features a removable plug for easy internal maintenance and cleaning.
- Pregled zaptivki: Check the VITON gasket for signs of wear, cracking, or chemical degradation. Replace if necessary to prevent leaks.
- Inspekcija zavojnice: Ensure the solenoid coil is free from physical damage or excessive heat buildup.
- Provjere curenja: Regularly check all connections for leaks.

7. Otkrivanje problema
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Ventil se ne otvara kada je pod naponom. | Nema napajanja, netačna jačina zvukatage, faulty coil, clogged orifice, plunger stuck. | Verify 12V DC power supply. Check electrical connections. Inspect coil for damage. Clean internal components. |
| Ventil se ne zatvara kada je bez napona. | Debris in valve, worn gasket, spring issue. | Clean valve internals. Inspect and replace gasket if necessary. |
| Leakage from valve body or connections. | Loose connections, damaged threads, worn gasket. | Tighten connections. Reapply thread sealant. Replace gasket. |
| Reduced flow through valve. | Partial clog, insufficient pressure. | Clean valve internals. Verify system pressure meets requirements. |
