Gardner Denver Minimum Pressure Valve 100015593 for Air Compressors

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.

• 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.

• 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)

• 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.

• 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)

• Parker Hannifin
• Bosch Rexroth
• Eaton/Vickers
• Sun Hydraulics
• Danfoss

• Regular Inspection: Check for leaks or pressure drops.
• Cleaning: Remove debris to prevent clogging.
• Calibration: Periodically verify pressure settings.
