Superior Chemical Resistance

Constructed from high-grade virgin PVDF, the flap type foot valve provides outstanding resistance to a wide spectrum of corrosive chemicals and harsh process fluids. The material choice combined with robust design ensures a long service life, even in the most demanding industrial environments.

Versatile Application and Customization

End connections can be customized to match ANSI, DIN, or BS piping standards, making these valves easily adaptable to a global range of industrial settings. Seat materialsPTFE, EPDM, or Vitonare selected based on chemical compatibility, maximizing safety and operational reliability.

Effortless Maintenance and Reliable Performance

The unique flap design allows for easy servicing without requiring valve removal. Operators benefit from simple maintenance routines, reduced downtime, and consistent leak-proof closure to prevent contamination or backflow.

FAQs of PVDF Flap Type Foot Valves:

Q: How is a PVDF Flap Type Foot Valve installed in a piping system?

A: The valve is installed vertically at the bottom end of a suction line pipe, ensuring it allows flow in one direction only while preventing backflow. Proper installation aligns with international pipe connection standards such as ANSI, DIN, or BS, which can be customized as needed.

Q: What media are suitable for PVDF Flap Type Foot Valves?

A: These valves are suitable for handling aggressive chemicals, acids, alkalis, water, and other corrosive fluids due to their 100% virgin PVDF construction and chemically resistant seals.

Q: When should I choose a PTFE, EPDM, or Viton seat material for my valve?

A: The selection of seat material depends on the chemical compatibility with your process fluid. PTFE is ideal for aggressive chemicals, EPDM for general water or non-oily substances, and Viton is best for strong acids or organic solvents.

Q: Where can PVDF Flap Type Foot Valves be used?

A: These valves are widely used in chemical process plants, water treatment facilities, and any industry where superior corrosion resistance and non-return function are required.

Q: What are the benefits of using PVDF Flap Type Foot Valves?

A: Benefits include high corrosion resistance, long operational life, reliable prevention of backflow, compatibility with industry-standard connections, and easy maintenance without removal from installation.

Q: How do I maintain a PVDF Flap Type Foot Valve?

A: Routine maintenance is simple and can be performed without dismantling the valve from the pipe. Regular inspection and cleaning of the flap and gasket help ensure leak-proof operation and longevity.

Q: What process specifications should be considered when selecting a valve size?

A: Valve size selection depends on the required port size for your application, available from 15 mm up to 225 mm. Consider maximum working pressure (up to 6 kg/cm), flow rates, and piping system standards for optimal fit and performance.
