A Polyvinylidene Fluoride (PVDF) butterfly valve is a type of valve commonly used for regulating or isolating the flow of fluids in industrial processes, particularly in applications where corrosive or aggressive media are present. PVDF, known for its excellent chemical resistance and mechanical properties, makes it an ideal material for constructing butterfly valves intended for challenging environments.
It's essential to consult the manufacturer's specifications and guidelines to ensure that the PVDF butterfly valve meets the specific requirements of your application in terms of size, pressure rating, temperature range, and compatibility with the intended fluid and operating conditions.
In summary, PVDF butterfly valves offer excellent chemical resistance, temperature stability, and mechanical strength, making them a reliable choice for handling corrosive fluids in demanding industrial applications.
Specifiation
Material:
PVDF (Polyvinylidene Fluoride) for the body, disc, and shaft. Other materials might include stainless steel for the stem or EPDM/Viton for the sealing elements.
Size Range:
PVDF butterfly valves are available in various sizes, typically ranging from small diameters (e.g., 1/2 inch) up to several feet in diameter for industrial applications.
Pressure Rating:
The pressure rating indicates the maximum pressure the valve can withstand while maintaining proper functionality. PVDF butterfly valves can typically handle pressures ranging from a few psi (pounds per square inch) up to several hundred psi, depending on the size and design.
Temperature Range:
PVDF butterfly valves have a temperature range within which they can operate effectively without compromising their mechanical properties. This range is typically from -20°C to 140°C (-4°F to 284°F) for standard PVDF material, although variations with higher or lower temperature capabilities might be available for specific applications.
Sealing Material:
The sealing material, usually EPDM or Viton, determines the compatibility of the valve with different fluids and temperature ranges. EPDM is suitable for general-purpose applications, while Viton provides enhanced chemical resistance and temperature resistance.
Actuation:
PVDF butterfly valves can be operated manually (with a hand lever or gear operator) or automated (with an electric or pneumatic actuator) based on the application's requirements for control and automation.
Standards Compliance:
PVDF butterfly valves may conform to industry standards such as
ANSI (American National Standards Institute)
ASTM (American Society for Testing and Materials)
DIN (Deutsches Institut für Normung)
ISO (International Organization for Standardization)
ensuring quality and compatibility with existing piping systems.
