Wolo Electric Solenoid Air Valve Model 812-EV Instruction Manual

Model: 812-EV

1. Увод

This manual provides detailed instructions for the installation, operation, and maintenance of the Wolo Electric Solenoid Air Valve, Model 812-EV. This universal valve is designed for controlling air flow in various automotive pneumatic systems, such as air horns. Please read this manual thoroughly before installation and operation to ensure proper function and safety.

2. Безбедносне информације

Увек се придржавајте следећих мера предострожности:

  • Ensure the vehicle's electrical system is disconnected before performing any electrical wiring.
  • Verify that the power supply matches the valve's voltagзахтеви (12V једносмерне везе).
  • Користите одговарајући алат и носите заштитне наочаре током инсталације.
  • Ensure all air connections are secure and leak-free to prevent pressure loss.
  • Do not exceed the recommended operating pressure for the valve or connected components.

3. Садржај пакета

The Wolo Electric Solenoid Air Valve package includes the following items:

  • Wolo Electric Solenoid Air Valve Unit (Model 812-EV)
  • 1/4 inch O.D. Brass Fittings
  • Монтажни хардвер
  • Упутство за употребу (овај документ)

4. Подешавање и инсталација

Follow these steps for proper installation of the solenoid air valve:

4.1 Монтажа вентила

  1. Select a suitable, secure location for mounting the valve. The location should be protected from excessive heat, moisture, and physical damage.
  2. Use the provided mounting bracket and hardware to firmly attach the valve to a stable surface. Ensure the valve is oriented correctly for air flow, if indicated on the unit.

4.2 Air Connections

  1. Connect the air supply line to the inlet port of the valve. The valve features 1/4 inch NPT threaded ports.
  2. Connect the air output line (e.g., to an air horn) to the outlet port of the valve.
  3. Use the provided 1/4 inch O.D. brass fittings. Apply thread sealant (e.g., PTFE tape or liquid sealant) to all threaded connections to ensure an airtight seal and prevent leaks.
  4. Tighten all connections securely, but do not overtighten, which can damage the threads or fittings.

4.3 Електричне везе

  1. The solenoid valve operates on 12V DC power. Connect one of the valve's electrical wires to a switched 12V DC positive (+) power source.
  2. Connect the other electrical wire to a reliable ground (-) point on the vehicle chassis.
  3. It is recommended to install an inline fuse (not included) on the positive power line to protect the circuit.
  4. Уверите се да су сви електрични прикључци безбедни и изоловани како бисте спречили кратки спојеви.

5. Упутство за употребу

The Wolo Electric Solenoid Air Valve functions as an on/off switch for air flow:

  • When 12V DC power is applied to the electrical wires, the solenoid energizes, opening the valve and allowing air to flow from the inlet to the outlet.
  • When the 12V DC power is removed, the solenoid de-energizes, closing the valve and stopping the air flow.

Ensure your air supply system (e.g., air compressor and tank) is properly pressurized before operating the valve.

6. Одржавање

The Wolo Electric Solenoid Air Valve is designed for minimal maintenance. However, periodic checks can ensure optimal performance and longevity:

  • Визуелни преглед: Regularly inspect the valve for any signs of physical damage, corrosion, or loose connections.
  • Ваздушне везе: Periodically check all air line connections for leaks. If a leak is detected, tighten the fitting or reapply thread sealant as necessary.
  • Електричне везе: Ensure electrical wires are securely connected and insulation is intact.
  • чистоћа: Keep the valve free from dirt, dust, and debris. Use a soft, dry cloth for cleaning.

КСНУМКС. Решавање проблема

If you encounter issues with your Wolo Electric Solenoid Air Valve, refer to the following troubleshooting guide:

ПроблемМогући узрокРешење
Valve does not open or closeNo electrical power; incorrect wiring; faulty switch; low air pressure; valve obstruction.Check 12V DC power supply and ground connections. Verify switch functionality. Ensure air supply system is pressurized. Inspect valve for debris.
Цурење ваздуха из прикључакаLoose fittings; insufficient thread sealant; damaged threads or fittings.Tighten fittings. Disassemble, reapply thread sealant, and reassemble connections. Replace damaged fittings if necessary.
Reduced performance in cold temperaturesInternal components affected by low temperatures.This can be a characteristic of some solenoid valves. If possible, relocate the valve to a warmer area or insulate it. Allow the vehicle to warm up before operation.
