Gardner Denver QX101907 Minimum Pressure Valve 150 PSI

Minimum Pressure Valve – Product Overview

1. What is a Minimum Pressure Valve?

A Minimum Pressure Valve (MPV) is a type of pressure control valve designed to maintain a minimum system pressure in hydraulic or pneumatic systems. It ensures that pressure does not drop below a preset level, protecting equipment from damage due to low pressure.

2. Key Features

• Pressure Regulation: Maintains a consistent minimum pressure in the system.

• Safety Protection: Prevents damage to pumps, compressors, and other components due to low pressure.

• Adjustable Settings: Many MPVs allow for manual or automatic adjustment of the minimum pressure threshold.

• Durable Construction: Typically made from materials like brass, stainless steel, or carbon steel for high-pressure resistance.

• Check Valve Function: Some MPVs incorporate a check valve to prevent backflow.

3. Applications

• Hydraulic Systems (e.g., industrial machinery, presses)

• Pneumatic Systems (e.g., air compressors, gas pipelines)

• Lubrication Systems (ensures oil pressure remains stable)

• Water & Process Systems (prevents pump cavitation)

4. Types of Minimum Pressure Valves

• Direct-Acting MPV: Simple design, operates based on spring tension.

• Pilot-Operated MPV: More precise, used in high-pressure systems.

• Inline MPV: Installed directly in the pipeline.

• Cartridge MPV: Compact, designed for integration into hydraulic manifolds.

5. Benefits

✔ Prevents system damage from pressure drops
✔ Improves efficiency by maintaining optimal pressure
✔ Reduces maintenance costs by avoiding pump cavitation
✔ Versatile for various industrial applications

6. Selection Criteria

• Pressure Range (PSI/Bar rating)

• Flow Rate (GPM or LPM)

• Material Compatibility (corrosion resistance)

• Connection Type (NPT, BSP, flanged, etc.)

• Adjustability (fixed or adjustable settings)

7. Leading Manufacturers

• Parker Hannifin

• Bosch Rexroth

• Eaton/Vickers

• Sun Hydraulics

• Danfoss

8. Maintenance & Troubleshooting

• Regular Inspection: Check for leaks or pressure drops.

• Cleaning: Remove debris to prevent clogging.

• Calibration: Periodically verify pressure settings.

Conclusion

A Minimum Pressure Valve is essential for maintaining system integrity in hydraulic and pneumatic applications. By ensuring pressure never falls below a safe threshold, it enhances equipment lifespan and operational efficiency.
