Full Lined PFA Plug Valve

NSV Full Lined PFA Plug Valve

This full-lined PFA plug valve is designed for low-to-medium pressure service with a rating of Class 150. The body is made of carbon steel (WCB), fully lined with PFA to completely isolate the process media from metal—eliminating contamination and corrosion.

The PFA lining offers exceptional chemical resistance, ultra-high purity, and non-stick performance, making it ideal for semiconductor, pharmaceutical, electroplating, and high-purity chemical applications. The tapered plug design ensures reliable shut-off. Manual actuation enables quick 90°operation with minimal maintenance.
