Product Description
Ingersoll-Rand Minimum Pressure Valve 42855437 - High Quality Screw Air Compressor Parts
Product Introduction: Minimum Pressure Valve (MPV)
What is a Minimum Pressure Valve?

A Minimum Pressure Valve (MPV), also known as a Minimum Pressure Check Valve or Pressure Holding Valve, is an automatic, spring-loaded precision valve designed to maintain a pre-set minimum system pressure in a fluid power circuit. Its primary function is to prevent system pressure from falling below a critical threshold, ensuring optimal operation and protection of downstream components.

Key Function & Purpose

The MPV acts as a guardian of your hydraulic or pneumatic system. It remains closed until a pre-determined "cracking pressure" is achieved upstream. Once this pressure is reached and surpassed, the valve opens to allow full flow.

  • Maintain Load Holding: Prevents loads from dropping uncontrollably in cylinders or hydraulic motors due to pressure loss
  • Ensure Pump Lubrication: Keeps adequate pressure on lubricated pumps to prevent damage from running dry
  • Avoid Cavitation: Prevents vacuum conditions that can cause cavitation in pumps and actuators
  • Sequencing: Ensures actuators don't operate until minimum system pressure is available
  • Pressure Safety: Guarantees baseline pressure for critical system functions
How It Works (Operating Principle)
  1. Closed Position: Spring force holds valve poppet closed against its seat
  2. Cracking Pressure: Upstream pressure overcomes spring force, valve begins to open
  3. Fully Open: At operating pressures above set point, valve remains fully open
  4. Re-closing: If upstream pressure drops, spring force closes valve to preserve downstream pressure
Key Features & Benefits
Feature Benefit
Precision Spring Setting Accurate and reliable minimum pressure setting, customizable for specific needs
Low Pressure Drop Full flow with minimal energy loss when open, improving system efficiency
Robust Poppet & Seat Design Excellent sealing in closed position, ensuring zero leakage and reliable pressure holding
Compact & Rugged Construction Designed to ISO/SAE standards for easy integration, withstands high pressures and harsh environments
Optional Check Valve Function Allows free reverse flow when certain pressure differential is met
Technical Specifications (Typical Range)
  • Pressure Rating: Up to 5,000 PSI (350 bar) and higher
  • Setting Range: Typically adjustable from 50 to 500 PSI (3.5 to 35 bar)
  • Port Sizes: Common from SAE #4 to #12 (e.g., 1/2" to 1-1/2" NPT)
  • Fluid Compatibility: Mineral-based hydraulic oil, synthetic fluids, water-glycol
  • Temperature Range: Standard seals from -20°C to 100°C (-4°F to 212°F)
Common Applications
  • Mobile Machinery: Excavators, bulldozers, cranes, telehandlers, forklifts
  • Industrial Machinery: Injection molding machines, presses, stamping presses
  • Pump Outlets: Mounted directly on piston, vane, and gear pumps
  • Hydraulic Circuits: Winch, brake, and motor circuits to prevent load runaway
  • Test Rigs: Maintain baseline pressure in complex test circuits
Why Choose Our Minimum Pressure Valve?
  • Superior Reliability: Hardened steel poppet and seat precision lapped for perfect seal
  • Easy Adjustment & Installation: Externally accessible adjustment screw for simple pressure setting
  • Proven Performance: Rigorously tested under real-world conditions
  • Global Support & Availability: Backed by worldwide technical support network
