TVKnife Gate Valve

Stafsjö’s SLV knife gate valve is specifically designed for handling abrasive and demanding slurry applications, prioritizing operational reliability and low life cycle costs. The SLV model features a lugged design, making it suitable for a variety of installation environments. Its counterpart, the SLF, is a fully flanged valve ideal for use in older non-centered pipes or in low-pressure applications.
