The Neles PB Series PFA-Lined Full-Port Ball Valve is an industrial valve with flanged connections and a flow passage and internal components completely covered with PFA. The valve is available in nominal sizes DN 15–100, with an operating temperature range of -30 to +160 °C, and meets the EN PN 16 and ASME Class 150 pressure ratings. The full-port design effectively reduces pressure loss, making the valve suitable for conveying inorganic strong acids such as sulfuric acid, shutoff of chlorine and bromine media, and isolation in seawater and brine treatment pipelines.

Application scenarios
Inorganic Strong Acid Transport and Isolation Pipelines
Suitable for shutoff and isolation in storage, transport and process pipelines handling corrosive inorganic acids such as sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid. The flow passage and internal components are fully covered with PFA for corrosion resistance, with flanged connections and a full-port design.
Chlorine Gas and Bromine Media Pipeline Shutoff
Suitable for connecting pipelines and transport branches serving process equipment that handles chlorine gas or bromine media, for flow-path shutoff and isolation. The flow passage and internal components are fully covered with PFA, providing a corrosion-resistant media-contact structure.
Seawater and Brine Treatment Pipelines
Suitable for on-off control and isolation in pipelines associated with seawater, brine and high-salinity water treatment. PFA fully covers the flow passage and internal components for applications requiring corrosion-resistant media-contact surfaces. The full-port design helps reduce pressure loss.
Selection points
Full PFA Lining of the Flow Passage and Internal Components
The flow passage and internal components are fully covered with PFA, making the valve suitable for media conditions requiring corrosion protection.
Full-Port Flow Passage with Low Pressure Drop
The full-port design minimizes pressure loss and provides high flow capacity.
Flanged Connections with Standardized Size and Pressure Ratings
The valve uses flanged connections and is available in sizes from DN 15 to 100 or NPS 1/2 to 6. Face-to-face dimensions comply with EN 558 and ASME B16.10, with pressure ratings of EN PN 16 and ASME Class 150.
Installation notes
Strictly observe operating temperature and pressure limits
Before installation and commissioning, confirm that the pipeline pressure does not exceed EN PN 16 or ASME Class 150 and that the media temperature is within the range of -30 (-10) to +160 °C.
Prevent damage to the PFA lining
During installation, purging and maintenance, prevent hard foreign objects or tools from scratching the PFA lining on the flow passage and internal components to maintain lining integrity.
FAQ
How does the Neles PB Series PFA-Lined Ball Valve combine corrosion resistance with flow capacity?
The series features a full-port design that reduces flow resistance and pressure loss while providing high flow capacity. The flow passage and internal components are completely covered with PFA, making the valve suitable for process media applications requiring enhanced corrosion resistance.
What nominal sizes and pressure ratings are available for the Neles PB Series PFA-Lined Ball Valve?
The series covers nominal sizes from DN 15 to DN 100, corresponding to NPS 1/2 inch to 6 inch. The pressure ratings are EN PN 16 and ASME Class 150. During selection, confirm compatibility with the applicable piping standard, connection dimensions and actual process pressure.
How should the flanged connection and face-to-face dimensions of the PB Series Ball Valve be matched to an existing pipeline?
The series is a flanged, seat-supported, full-port ball valve with face-to-face dimensions conforming to EN 558 and ASME B16.10. For engineering integration, verify the existing pipeline flange standard, face-to-face dimensions, nominal size and pressure rating to ensure interface compatibility.
What is the applicable temperature range of the Neles PB Series PFA-Lined Ball Valve?
The temperature range for the series is -30 (-10) to +160 °C. The actual operating temperature should also be confirmed based on the specific model and application conditions.
What key points should be considered when installing and maintaining the Neles PB Series PFA-Lined Ball Valve?
Before installation, confirm that the valve nominal size, flange interface, face-to-face dimensions, pressure rating and temperature conditions match the pipeline system. During operation and maintenance, pay particular attention to keeping the full-port flow passage clear and ensuring that the PFA-covered flow passage and internal components are suitable for the current media and operating conditions. The specific configuration must be confirmed based on the actual model and application conditions.
