PVDF Actuated Butterfly Valve Graphics

PVDF Actuated Butterfly Valve

A PVDF Actuated Butterfly Valve is a quarter-turn valve made from Polyvinylidene Fluoride (PVDF) that controls the flow of fluids through a piping system using an actuator instead of manual operation. The PVDF Actuated Butterfly Valve consists of a PVDF body and disc and can be equipped with either: Pneumatic actuator – air-driven for fast automation and Electric actuator – motor-driven for remote or precise control. This allows the valve to open, close, or modulate the flow automatically without manual intervention.

The PVDF Actuated Butterfly Valve is a high-performance flow control device engineered for precision and durability in highly corrosive and chemically aggressive environments. Ideal for use in chemical processing, oil and gas treatment, semiconductor, and pharmaceutical industries, it offers excellent resistance to acids, bases, and solvents. Its robust design ensures long service life, even under harsh operating conditions.

  • Reduces manual intervention in corrosive or hazardous environments

2. Fast and Reliable Operation

  • Quarter-turn (90°) mechanism enables quick opening and closing
  • Consistent performance in repeated cycles
  • Improves process efficiency and safety

3. Excellent Chemical Resistance

  • PVDF body and disc resist acids, alkalis, and aggressive chemicals
  • Compatible with highly corrosive industrial media
  • Long service life in harsh environments

4. Reduced Labor and Safety Risks

  • Automation eliminates the need for manual operation in dangerous or hard-to-access locations
  • Minimizes human error in valve operation

5. Flexible Mounting Options5. Flexible Mounting Options

  • Available in lug, wafer, or flanged types
  • Compatible with various pipeline standards (ANSI, DIN, JIS)
  • Can handle dead-end service depending on mounting

6. Versatile Actuation Types

  • Pneumatic actuators: fast response, suitable for chemical plants
  • Electric actuators: precise control, programmable, compatible with automated systems

7. Low Maintenance

  • PVDF construction prevents corrosion and scaling
  • Smooth internal surface reduces deposits and contamination
  • Longer operational life compared to metal valves in corrosive fluids

8. Cost-Effective in Corrosive Systems

  • Avoids the high cost of exotic metals like PVDF-resistant alloys
  • Reduced downtime and maintenance costs
  • Lightweight design reduces structural support needs

Types of PVDF Actuated Butterfly Valve

1. Based on Actuation Method

PVDF butterfly valves can be actuated using different mechanisms depending on the application:

  • Manual Actuated Butterfly Valves
      • Operated with a hand lever or gear operator.
      • Suitable for smaller pipelines and low-frequency operations.
      • Provides simple, cost-effective operation.
    1. Pneumatic Actuated Butterfly Valves
      • Use compressed air to rotate the valve disc.
      • Types:
        • Single-acting (spring return): Valve returns to default position when air supply is cut.
        • Double-acting: Air pressure controls both opening and closing.
      • Advantages: Fast operation, remote control capability.
  • Electric Actuated Butterfly Valves
    • Driven by an electric motor.
    • Can be integrated with automated control systems.
    • Types:
      • On/Off: Fully opens or closes the valve.
      • Modulating (throttle): Controls flow rate continuously.

2. Based on Valve Design

  • Wafer Type
      • Fits between two flanges.
      • Centered disc minimizes space requirements.
      • Common in pipelines where compactness is needed.
  • Lug Type
    • Has threaded inserts (lugs) to bolt directly to flanges.
    • Can be used for dead-end service; the downstream flange can be removed without disturbing the upstream connection.
  1. Flanged Type
    • Full flanges on valve body.
    • Provides strong structural integrity for high-pressure applications.

3. Based on Sealing Mechanism

  1. PTFE Seat
    • Offers excellent chemical resistance.
