PFA Lined Diaphragm Valve

Он PFA Lined Diaphragm Valve is designed for precise control of ultra-high purity and highly corrosive fluids. By combining a robust SCS13 stainless steel valve body with a fully molded PFA lining and a zero-leakage diaphragm structure, this valve ensures exceptional chemical resistance, contamination-free operation, and long-term reliability in critical process environments.

It is widely used in semiconductor manufacturing, pharmaceutical production, fine chemical processing, and high-purity water systems where safety, cleanliness, and corrosion resistance are essential.

Ultra-High Purity & Exceptional Chemical Resistance

This diaphragm valve features a complete PFA lining that fully isolates process media from all metallic components. This design effectively eliminates metal ion release and contamination risks, ensuring compatibility with semiconductor-grade and pharmaceutical-grade applications.

Он PFA/PTFE sealing surface provides outstanding resistance to strong acids, alkalis, oxidizers, and organic solvents, including highly aggressive chemicals commonly used in wet process and chemical delivery systems.

Zero Leakage Diaphragm Design

The valve adopts a diaphragm-type sealing structure, creating a physical barrier between the fluid chamber and the actuator. This design achieves true bubble-tight, zero external leakage, enhancing both operational safety and environmental protection.

The diaphragm also minimizes dead zones and prevents media accumulation, making the valve ideal for applications requiring high cleanliness and frequent flushing.

Long Service Life & Low Maintenance

Smooth PFA-lined flow paths and excellent anti-adhesion properties significantly reduce clogging and particle buildup. The wear-resistant diaphragm, combined with an optimized structural design, extends maintenance intervals and lowers total cost of ownership.

Он top-entry design allows diaphragm replacement without removing the valve from the pipeline, ensuring fast and convenient maintenance.

Reliable Performance in Demanding Environments

Rated to JIS 10K pressure class, the valve delivers stable and reliable performance under a wide range of operating conditions. The compact valve body structure ensures efficient installation, while optional manual, pneumatic, or electric actuators support both manual operation and automated control systems.
