Product Specifications

Technical details and manufacturing context for Solenoid Control Valves

Definition
Electromagnetic valves that regulate the flow of gases within Gas Flushing Units and Vacuum Pumps, enabling precise control over flushing cycles, pressure regulation, and system isolation through electrical signals.
Working Principle
When electrical current is applied to the solenoid coil, it creates a magnetic field that moves a plunger or armature, opening or closing the valve orifice to control gas flow. De-energizing the coil returns the valve to its default position via spring force.
Common Materials
Stainless steel, Brass, PTFE seals, Copper coil
Technical Parameters
  • Orifice diameter determining flow capacity (mm) Customizable
Components / BOM
  • Solenoid Coil
    Generates electromagnetic field when energized to actuate valve
    Material: Copper wire with insulation
  • Plunger/Armature
    Magnetic core that moves to open/close valve orifice
    Material: Magnetic stainless steel
  • Valve Body
    Houses internal components and provides connection ports
    Material: Stainless steel or brass
  • Seals
    Prevent gas leakage around moving parts and connections
    Material: PTFE or Viton
Engineering Reasoning
0.1-15 bar differential pressure, -20°C to +80°C ambient temperature, 12-24 VDC operating voltage
Coil burnout at >85°C winding temperature, seal failure at >20 bar differential pressure, mechanical binding at <0.05 bar differential pressure
Design Rationale: Joule heating exceeding PTC thermistor protection threshold (85°C), elastomer seal extrusion through gap at 20 MPa/mm gap pressure gradient, insufficient force to overcome stiction at low pressure differentials
Risk Mitigation (FMEA)
Trigger Voltage transient exceeding 36 VDC for >100 μs
Mode: Insulation breakdown and coil short circuit
Strategy: TVS diode clamping at 28 VDC with 600 W peak pulse power rating
Trigger Particulate contamination >25 μm in gas stream
Mode: Spool valve mechanical binding and position sensor misalignment
Strategy: 5 μm absolute filtration with differential pressure monitoring at 0.5 bar warning threshold

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Coil burnout
Cause: Overvoltage, excessive heat from high duty cycles, or moisture ingress leading to insulation breakdown and short circuits.
Spool sticking or binding
Cause: Contamination from particulates in fluid, wear debris, or varnish buildup due to fluid degradation, preventing proper movement.
Maintenance Indicators
  • Audible buzzing or humming from the solenoid coil, indicating improper seating or electrical issues.
  • Visible external leakage around valve body or solenoid housing, suggesting seal failure or cracks.
Engineering Tips
  • Implement a proactive filtration and fluid cleanliness program to ISO 4406 standards, reducing contamination-induced wear.
  • Use voltage stabilizers and ensure proper heat dissipation with adequate ventilation or cooling to prevent coil overheating.

Frequently Asked Questions

What materials are used in these solenoid control valves?

Our solenoid control valves are constructed from high-quality materials including stainless steel for the valve body, brass components, PTFE (Teflon) seals for chemical resistance, and copper solenoid coils for efficient electrical operation.

How do solenoid valves control gas flow in flushing systems?

When electrically energized, the solenoid coil creates a magnetic field that moves the plunger/armature, opening or closing the valve to precisely control gas flow in industrial flushing and vacuum applications.

What are the main components in your solenoid valve BOM?

The bill of materials includes four key components: the plunger/armature assembly, PTFE or similar high-performance seals, the solenoid coil (typically copper), and the main valve body (usually stainless steel or brass).
