The new Fabri-Valve XS150-ULV Urethane-Lined Knife Gate Valve utilizes superior sealing design and includes replaceable FV8000™ urethane liners to protect the valve body from abrasion and corrosion. The design features a robust perimeter seal that provides bi-directional, bubble-tight shutoff without discharging process media into the environment. The XS150-ULV is the ideal solution to common performance problems that typically plague knife gate valves in abrasive and corrosive applications found in industry — particularly in the power and mining sectors. The FV8000 urethane liner and perimeter seal are independent and work in harmony providing body protection and bubble-tight shutoff in abrasive and/or corrosive applications. Because the liner is independent of the perimeter seal, the urethane compound has the maximum hardness for superior abrasion resistance. A triple-scraper design is incorporated into the liners, which cleans the heavy duty gate during operation and prevents media build up in the chest area. The XS-150-ULV does not discharge process media into the environment and provides reliable shutoff. It is easy to maintain, and the one-piece perimeter seal is repairable under line pressure should the packing leak.
