Product Specifications

Technical details and manufacturing context for Pressure Regulation Valve

Definition
A critical component of a Vacuum Extraction Unit that precisely controls and stabilizes the internal pressure by regulating airflow, ensuring optimal vacuum performance and system safety during extraction processes.
Working Principle
Operates by adjusting the flow area or using a spring-loaded diaphragm mechanism to respond to pressure changes, opening or closing to maintain a set pressure point within the vacuum chamber.
Common Materials
Stainless Steel, Brass, PTFE (Seals)
Technical Parameters
  • Port/Connection Size (mm) Per Request
Components / BOM
  • Valve Body
    Main housing containing the flow path and pressure chamber.
    Material: Stainless Steel
  • Diaphragm
    Flexible membrane that responds to pressure changes to actuate the valve.
    Material: Elastomer (e.g., Nitrile, EPDM)
  • Adjustment Spring
    Provides the counterforce to set the desired pressure point.
    Material: Spring Steel
  • Seat & Seal
    Ensures a tight closure to prevent leaks when the valve is shut.
    Material: PTFE or Viton
Engineering Reasoning
0.1-2.0 bar absolute pressure
0.08 bar absolute pressure (vacuum collapse) or 2.2 bar absolute pressure (diaphragm rupture)
Design Rationale: Diaphragm material yield strength (316L stainless steel, 205 MPa) exceeded at 2.2 bar differential pressure; vacuum collapse occurs at 0.08 bar when atmospheric pressure (1.013 bar) overcomes valve's sealing force
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding 10 μm particle size
Mode: Seat erosion leading to 15% pressure regulation error
Strategy: Install 5 μm absolute filter upstream with differential pressure monitoring
Trigger Ambient temperature cycling between -20°C and 80°C at 5°C/min rate
Mode: Diaphragm material fatigue cracking after 10^5 cycles
Strategy: Replace standard EPDM diaphragm with fluorosilicone compound rated for -40°C to 150°C
