Please read this manual thoroughly before using the product to ensure proper function and to prevent damage or injury. Keep this manual for future reference.
Информация по безопасности
- Always wear appropriate personal protective equipment (PPE) such as safety glasses and gloves when working with hydraulic systems.
- Ensure the hydraulic system is depressurized before performing any installation, maintenance, or troubleshooting.
- High-pressure hydraulic fluid can cause serious injury. Never use bare hands to check for leaks.
- Убедитесь, что все соединения надежно закреплены и должным образом герметизированы, чтобы предотвратить протечки.
- Only qualified personnel should perform installation and maintenance procedures.

The VEVOR 2 Spool Hydraulic Directional Control Valve is designed for precise control of double-acting hydraulic cylinders in various applications. Its robust construction and high-performance capabilities make it suitable for demanding industrial and agricultural environments.
Основные характеристики
- Double Acting: Specifically engineered for operating double-acting hydraulic cylinders, allowing for controlled extension and retraction.
- Прочная конструкция: Manufactured from cast iron for enhanced durability and long-term reliability in harsh conditions. Features 2 spools and 1/2 BSPP O-ring inlet/outlet ports.
- Высокая производительность: Capable of handling pressures up to 3600 PSI and a maximum flow rate of 11 GPM, ensuring efficient hydraulic power delivery.
- Spring Return: Each spool valve is equipped with a spring return mechanism, automatically returning the lever to the neutral position when released.
- Широкое применение: Ideal for use in small tractors, tractor loaders, log splitters, and other hydraulic machinery requiring precise directional control.

3. Настройка и установка
3.1 Проверки перед установкой
- Verify that the valve specifications (pressure, flow, port size) match your hydraulic system requirements.
- Осмотрите клапан на наличие видимых повреждений, полученных при транспортировке.
- Ensure all necessary fittings, hoses, and mounting hardware are available.
3.2 Монтаж клапана
- Select a secure and accessible location for mounting the valve, away from excessive heat, vibration, and potential impact.
- Use appropriate bolts and washers to firmly attach the valve to a stable surface. Ensure the mounting surface can support the weight of the valve and the forces exerted during operation.
3.3 Connecting Hydraulic Lines
The valve features 1/2 BSPP O-ring inlet/outlet ports. Ensure proper thread type and size for all connections.
- Напорная линия (P): Connect the pressure line from your hydraulic pump to the 'P' port on the valve.
- Трубопровод (Т): Connect the return line to the hydraulic reservoir (tank) to the 'T' port.
- Work Ports (A & B): Connect the 'A' and 'B' ports for each spool to the respective ports on your double-acting hydraulic cylinders. For a 2-spool valve, you will have A1/B1 and A2/B2 ports.
- Use thread sealant or PTFE tape on all threaded connections to prevent leaks, ensuring not to block the fluid path.
- Tighten all fittings to the manufacturer's recommended torque specifications.

3.4 Initial System Checks
- After installation, slowly start the hydraulic pump and check for any leaks around the valve and connections.
- Operate the cylinders slowly through their full range of motion to bleed air from the system.
- Monitor system pressure and fluid levels.
4. Инструкция по эксплуатации
The VEVOR 2 Spool Hydraulic Directional Control Valve provides intuitive control over your hydraulic cylinders. Each lever controls one spool, corresponding to a pair of work ports (A and B).
4.1 Lever Positions
- Нейтральное положение: When the lever is in the center, the spool is in the neutral position. In this state, fluid flow to the work ports is blocked, and the cylinder remains stationary. The spring return mechanism ensures the lever returns to this position when released.
- Extend Position: Pushing the lever forward (or in one direction) directs hydraulic fluid to one work port (e.g., 'A'), causing the cylinder to extend.
- Retract Position: Pulling the lever backward (or in the opposite direction) directs hydraulic fluid to the other work port (e.g., 'B'), causing the cylinder to retract.

4.2 Общие правила эксплуатации
- Operate levers smoothly and avoid abrupt movements to prevent shock loads on the hydraulic system.
- Do not exceed the maximum operating pressure or flow rate specified for the valve.
- Regularly check for unusual noises, vibrations, or changes in performance during operation.

5. Техническое обслуживание
Proper maintenance ensures the longevity and reliable performance of your hydraulic control valve.
5.1 Регулярные проверки
- Ежедневно/Еженедельно: Check for any external leaks, loose connections, or visible damage to the valve body or levers.
- Ежемесячно/ежеквартально: Inspect hydraulic hoses and fittings for wear, cracks, or corrosion. Ensure mounting bolts are tight.
5.2 Гидравлическая жидкость
- Ensure the hydraulic fluid level in the reservoir is adequate and within the recommended range.
- Check the condition of the hydraulic fluid. Replace fluid and filters according to your hydraulic system manufacturer's recommendations or if the fluid appears contaminated.
- Using clean, appropriate hydraulic fluid is critical for valve performance and system health.
5.3 Очистка
- Keep the exterior of the valve clean and free from dirt, debris, and excessive oil buildup.
- Avoid using harsh chemicals that could damage seals or paint.
6. Поиск Неисправностей
Before attempting any repairs, ensure the hydraulic system is depressurized and secured.
