PFA Lined Ball Valve

El PFA Lined Ball Valve is specifically engineered for high-purity fluid handling and highly corrosive chemical control systems. Combining a precision-cast SCS13 stainless steel body with a full PFA (Perfluoroalkoxy) lining and PTFE sealing structure, this valve provides outstanding chemical corrosion resistance, ultra-clean fluid flow, and long-term sealing reliability.

Designed for demanding industrial environments, the valve is widely used in semiconductor manufacturing, photovoltaic production, chemical processing plants, pharmaceutical facilities, and high-purity fluid systems where chemical compatibility, contamination control, and operational reliability are critical.

Exceptional Corrosion Resistance for Aggressive Chemical Media

The valve’s internal flow path is fully lined with high-purity PFA or PTFE, effectively isolating the process fluid from metal components. This design allows the valve to safely handle strong acids, strong alkalis, oxidizing agents, organic solvents, and mixed corrosive chemicals.

Key benefits include:

• Excellent resistance to acidic and alkaline chemicals

• Compatibility with high-purity chemical fluids

• Protection against chemical corrosion and metal contamination

• Reliable performance in aggressive industrial environments

El ultra-smooth PFA surface minimizes adhesion, scaling, and particle generation, ensuring clean fluid transport and contamination-free processing.

High-Purity Flow Path for Contamination-Free Operation

El full-bore PFA lined design ensures an ultra-clean flow channel, which is essential for industries requiring strict contamination control. The inert fluoropolymer lining prevents interaction between the valve body and the process media.

This makes the valve ideal for:

• Ultra-pure chemical delivery systems

• DI water and ultrapure water pipelines

• pharmaceutical fluid transfer

• semiconductor wet processing lines

By maintaining media purity and process integrity, the valve supports sensitive manufacturing processes that require strict cleanliness standards.

Reliable Sealing Performance and Zero Leakage Protection

The valve features an optimized ball and seat sealing structure using PTFE or PFA sealing surfaces, delivering excellent elasticity and chemical stability. This design ensures tight shut-off capability and bubble-tight sealing performance, even during frequent operation.

Key sealing advantages include:

• Zero leakage performance

• Excellent chemical and thermal stability

• Consistent sealing under pressure fluctuations

• Reduced risk of process fluid loss or contamination

El SCS13 stainless steel valve body (equivalent to CF8 / 304 stainless steel) provides superior mechanical strength and structural stability, ensuring reliable operation under demanding industrial conditions.

Wide Temperature Range and Long Service Life

The advanced PFA lining material provides outstanding resistance to thermal aging, creep deformation, and chemical attack. This allows the valve to operate reliably across a wide temperature range.

Typical operating conditions include:

• Temperature range: -20°C to +150°C (depending on pressure conditions)

• Excellent resistance to abrasion and chemical degradation

• Long service life in corrosive chemical environments

These characteristics significantly reduce maintenance requirements and lower the total cost of ownership (TCO) while improving overall system reliability.

Flexible Installation and Automation Compatibility

El PFA lined ball valve is designed for easy installation and integration into modern pipeline systems. It is available with standard ISO flange connections and multiple configuration options.

Available options include:

• Flanged PFA lined ball valve

• Wafer-type ball valve

• Manual lever operation

• Pneumatic actuator ball valve

• Electric actuator ball valve

This flexibility allows the valve to support automated process control systems, remote monitoring, and industrial automation platforms.
