PFA Lined Diaphragm Valve

PFA Lined Diaphragm Valve

The PFA Lined Diaphragm Valve represents a superior engineering solution for industries requiring high-purity flow control, exceptional corrosion resistance, and long-term reliability. Manufactured in strict accordance with international quality and performance standards, these valves are purpose-built for demanding chemical, pharmaceutical, water treatment, and industrial processing environments.

ADVECT’s advanced design ensures complete isolation of line media from the valve’s mechanical and functional components, preventing contamination, corrosion, and premature wear. This separation is essential for maintaining product purity, protecting internal mechanisms, and ensuring consistent operational efficiency even under aggressive process conditions.

One of the valve’s most valuable advantages is its air-tight shut-off, delivering absolute sealing integrity across a wide variety of applications. This feature enhances plant safety, minimizes leakage risks, and ensures dependable system performance. Additionally, the top-entry design provides easy access for inspection, cleaning, and maintenance, significantly reducing downtime and enhancing overall plant productivity.

The valve incorporates a technologically advanced PTFE diaphragm pad, reinforced with EPDM rubber and backed by neoprene, creating a multilayer structure that offers superior durability, flexibility, and chemical resistance. This diaphragm configuration ensures precise flow regulation, extended service life, and reduced maintenance interaction—making it ideal for both on-off and modulating flow control applications.

Clients benefit from a versatile selection of body materials, including ductile iron, carbon steel, and stainless steel, allowing them to choose the best match for their specific process, temperature, and pressure requirements. Regardless of material selection, each valve undergoes rigorous testing and quality assurance checks to meet ADVECT’s high standards of performance and reliability.

With its corrosion-proof PFA lining, mechanical isolation, robust diaphragm construction, and maintenance-friendly architecture, the ADVECT PFA Lined Diaphragm Valve is exceptionally well suited for the safe handling of corrosive chemicals, slurries, high-purity liquids, and sensitive process media. It is a trusted solution for industries seeking longevity, operational stability, and outstanding flow control performance.
