Pneumatic screw regulating reversing valve

Usage Recommendations

1. Installation Guidelines

  • Ensure that the valve body is aligned properly with the pipeline to avoid stress on the internal components.

  • Use the appropriate sealants and gaskets based on the type of fluid in your system to prevent leakage.

  • Verify air pressure before installing the valve. The operating air pressure should fall within the recommended range (4 to 8 bar) for smooth actuation.

2. System Integration

  • Integrate the Pneumatic Screw Regulating Reversing Valve with your PLC or SCADA system for seamless control and monitoring.

  • Use a control valve interface to adjust pneumatic signals, allowing for optimal flow regulation and precise switching between flow directions.

3. Operating Conditions

  • Avoid exceeding the pressure rating of the valve (0-40 bar) to ensure safe and reliable operation.

  • Regularly check the air quality supplied to the valve. Ensure that the air is clean and dry to avoid internal contamination, which can cause actuator failure.

  • Ensure the valve is compatible with the fluids in your system. For example, use chemical-resistant seals for aggressive chemicals and food-grade materials for sanitary applications.


Maintenance Tips

1. Routine Inspections

  • Inspect the valve body and actuator for signs of wear or leakage. Regularly check for air leaks in the pneumatic system, which can reduce efficiency and cause excessive wear on the valve.

  • Ensure the actuating mechanism moves freely without obstruction and is free from dirt or debris that could impair its functionality.

2. Lubrication

  • Periodically lubricate the moving parts of the valve actuator to reduce friction and ensure smooth operation. Use manufacturer-approved lubricants compatible with your valve's materials.

  • Lubricate threads and seals as needed, especially in high-cycle operations, to prevent wear and extend the valve’s lifespan.

3. Seal Replacement

  • Replace seals when signs of wear or leakage appear. Depending on the application, seal replacement intervals can vary from 12 months to 24 months.

  • Always use genuine replacement parts to maintain optimal performance and prevent compatibility issues.

4. Cleaning

  • Clean the valve body and actuator regularly, especially when operating in dusty or dirty environments. Use appropriate cleaning solutions that do not degrade the valve’s material or seals.

  • Ensure the valve remains free of contaminants, as dirt or moisture can cause blockages or premature wear.


Energy-Saving Standards

1. Low Air Consumption

  • The Pneumatic Screw Regulating Reversing Valve is designed to optimize air consumption, reducing operational costs compared to other valve types.

  • Minimize air leakage by using high-quality seals and ensuring the valve is properly installed and maintained.

2. Optimized Air Pressure

  • Ensure the pneumatic air supply operates within the recommended pressure range (4-8 bar). Over-pressurizing the system increases energy consumption without improving performance.

  • Use a pressure regulator to ensure the air pressure is consistent and energy-efficient.

3. System Integration for Energy Efficiency

  • Integrate the valve with smart automation systems that adjust air flow based on real-time needs. This allows for dynamic operation, preventing waste and improving overall energy savings.

  • By combining the Pneumatic Screw Regulating Reversing Valve with an energy-efficient compressor and proper filtration system, you can further enhance energy savings.
