Built on Richter’s PFA lined NK series, the NKS-T/F Butterfly Valve is designed to fit with the TE/F Bottom Valve, it can, however, also be used on top of the tank container. The sandwich-type body is equipped with PTFE and the disc is lined with PFA for maximum corrosion resistance. The single piece disc / stem is maintenance free and the selfadjusting top and bottom stem sealing warrants reliability, even with many switching cycles.
The simple yet ingenious acentric hand lever is equipped with a locking mechanism and is designed with ultimate flexibility in mind to allow for secure and easy operation in small spaces. The NK series are known for their reliable and durable construction, while displaying high performance
