Pneumatic FEP / PFA Lined Floating Ball Valve

A Pneumatic FEP/PFA Lined Floating Ball Valve is a specialized industrial valve designed to provide reliable flow control for highly corrosive or chemically aggressive media. Here's a detailed overview of its components, functions, and typical applications:

• Pneumatic Actuator: Powers the valve using compressed air to automate opening and closing.

• FEP/PFA Lining:

  • FEP (Fluorinated Ethylene Propylene) and PFA (Perfluoroalkoxy) are fluoropolymers known for exceptional chemical resistance.

  • These linings protect the internal surfaces of the valve from corrosive fluids.

• Floating Ball:

  • The ball "floats" slightly within the valve body and is pushed against the downstream seat by pressure, creating a tight seal.

  • Ideal for low- to medium-pressure applications.

• Body Materials: Typically carbon steel or stainless steel lined internally with FEP/PFA.

• Seats: Often made of PTFE or reinforced PTFE, compatible with the lining for full corrosion resistance.

• Corrosion Resistance: Withstands strong acids, alkalis, and solvents.

• Leak Tightness: Ensures zero leakage due to the floating ball design.

• Automation Ready: Integrated pneumatic actuator allows remote or automated operation.

• Clean Operation: Non-contaminating, suitable for high-purity applications.

• Chemical Processing

• Pharmaceuticals

• Water Treatment (Acid Dosing)

• Food and Beverage (when chemical cleaning is involved)

• Pulp and Paper (bleaching lines)
