Product Specifications

Technical details and manufacturing context for Orifice / Nozzle

Definition
The orifice/nozzle is a critical part of an injection valve that precisely regulates the flow rate, velocity, and spray pattern of fluids being injected. It creates a controlled restriction in the flow path, converting pressure energy into kinetic energy to achieve desired injection characteristics.
Working Principle
Fluid enters the orifice/nozzle under pressure, accelerates as it passes through the constricted opening, and exits with controlled velocity and direction. The geometry of the orifice/nozzle determines flow characteristics, pressure drop, and spray pattern.
Common Materials
Stainless Steel, Tungsten Carbide, Ceramic
Technical Parameters
  • Orifice diameter or nozzle opening size (mm) Standard Spec
Components / BOM
  • Orifice Plate
    Creates the flow restriction and controls flow rate
    Material: Stainless Steel
  • Nozzle Body
    Houses the orifice and provides connection to valve
    Material: Stainless Steel
  • Spray Tip
    Shapes and directs the fluid spray pattern
    Material: Tungsten Carbide
Engineering Reasoning
0.5-350 bar differential pressure, 0.1-50 L/min flow rate, -40°C to 150°C temperature
Cavitation inception at vapor pressure ≤ 0.023 bar absolute, erosion failure at flow velocity > 45 m/s, thermal stress cracking at ΔT > 80°C
Design Rationale: Cavitation-induced erosion from localized pressure drop below fluid vapor pressure (Bernoulli principle), thermal fatigue from cyclic temperature gradients exceeding material yield strength, abrasive wear from particle impingement at high velocity
Risk Mitigation (FMEA)
Trigger Particulate contamination > 10 μm in fluid stream
Mode: Orifice erosion and diameter increase > 5% tolerance
Strategy: Install 5 μm absolute filtration upstream with differential pressure monitoring
Trigger Water hammer pressure surge exceeding 1.5x design pressure
Mode: Plastic deformation or brittle fracture of nozzle body
Strategy: Integrate accumulator with 0.5 L capacity and 10 ms response time for surge dampening

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 10,000 psi (690 bar)
flow rate: 0.1 to 500 GPM (0.38 to 1893 L/min)
temperature: -40°C to 400°C (dependent on material)
slurry concentration: Max 5% solids by weight (for standard designs)
Media Compatibility
✓ Hydraulic fluids ✓ Process chemicals ✓ Compressed gases
Unsuitable: Abrasive slurries with high solids content
Sizing Data Required
  • Required flow rate (GPM or L/min)
  • System pressure differential (psi or bar)
  • Fluid properties (density, viscosity)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive erosion
Cause: High-velocity flow of particulate-laden fluids causing material degradation and dimensional changes, leading to inaccurate flow measurement and potential leakage.
Cavitation
Cause: Pressure drop below vapor pressure causing bubble formation and implosion, resulting in pitting, vibration, and structural damage to the orifice/nozzle surface.
Maintenance Indicators
  • Audible high-frequency whistling or hissing indicating flow restriction or damage
  • Visible flow measurement drift exceeding ±2% from calibrated values on downstream instruments
Engineering Tips
  • Implement upstream filtration (≥40 micron) and regular fluid analysis to minimize particulate ingress and erosion potential
  • Maintain upstream pressure at least 2.5× downstream pressure to prevent cavitation, and select erosion-resistant materials (e.g., hardened stainless steel, ceramic coatings) for high-velocity applications
