Product Specifications

Technical details and manufacturing context for Flow Control Valve/Meter

Definition
A critical component within Purge Air Systems that simultaneously controls the flow rate of purge air and provides precise measurement of that flow. It ensures optimal air delivery for processes like equipment cooling, contamination prevention, or pressure maintenance in various industrial applications.
Working Principle
The valve component adjusts the flow area via manual, pneumatic, or electric actuation to regulate air volume, while the meter component (typically using differential pressure, thermal, or turbine principles) measures the actual flow rate. The integrated design allows for real-time flow adjustment based on measurement feedback.
Common Materials
Stainless steel, Brass, PTFE seals, Aluminum alloy
Technical Parameters
  • Connection size (e.g., 1/2", 3/4", 1") (mm) Customizable
Components / BOM
  • Valve Body
    Main housing containing flow passage and connection ports
    Material: Stainless steel or brass
  • Flow Meter Sensor
    Detects and measures air flow rate using various principles
    Material: Stainless steel with electronic components
  • Control Mechanism
    Adjusts valve opening to regulate flow (knob, actuator, etc.)
    Material: Aluminum alloy with plastic components
  • Seals and Gaskets
    Ensure leak-proof connections and internal sealing
    Material: PTFE, Viton, or EPDM rubber
  • Display/Output Module
    Shows flow readings and provides output signals
    Material: Polycarbonate with electronic circuitry
Engineering Reasoning
0.5-15.0 bar at 20°C with 0.1% accuracy
18.5 bar differential pressure causing diaphragm rupture
Design Rationale: Diaphragm material yield strength (316L stainless steel) exceeded at 250 MPa stress due to Bernoulli's principle pressure differential
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding 10 μm in purge air stream
Mode: Orifice plate erosion causing 15% flow measurement error
Strategy: Install 5 μm absolute filter with differential pressure monitoring at 0.3 bar warning threshold
Trigger Ambient temperature cycling between -40°C and 120°C
Mode: Thermal expansion mismatch between 316L stainless steel body and PTFE seals causing 0.2 mm gap leakage
Strategy: Implement bellows-sealed stem design with Inconel 718 spring compensating for 0.15 mm thermal displacement

Frequently Asked Questions

What industries commonly use this flow control valve/meter?

This device is designed for machinery and equipment manufacturing, specifically for industrial systems requiring precise purge air flow regulation and measurement, such as pneumatic systems, processing equipment, and automated machinery.

How does the combined valve and meter function improve system performance?

By integrating flow regulation and measurement into a single unit, it reduces installation points, minimizes potential leak points, ensures consistent calibration between control and measurement, and simplifies maintenance in industrial air systems.

What maintenance is required for the PTFE seals and stainless steel components?

PTFE seals offer excellent chemical resistance and low maintenance; periodic inspection for wear is recommended. Stainless steel components require standard industrial cleaning to prevent corrosion buildup; the valve body and sensor should be checked during routine system maintenance cycles.
