Fabri-Valve XS150 High Performance Knife Gate Valve
The Fabri-Valve XS150 is a high-performance, true full-port knife gate valve for severe abrasive slurry and demanding industrial isolation. Its double-locked one-piece perimeter and chest seal delivers repeatable bubble-tight shutoff in both directions, exceeding the most stringent industry leakage class for isolation valves.
Product Benefits
- Seal that stays tight: Where ordinary knife gates gradually lose their seal, the XS150's one-piece perimeter and chest seal is double-locked into the body, so shutoff stays bubble-tight cycle after cycle.
- Verified leakage class: Sealing performance is verified beyond the tightest standard leakage classification for isolation valves.
- Dead-end capable: Because it seals bi-directionally, the valve handles dead-end service at its full pressure-temperature rating.
- Injectable packing: Packing can be adjusted under line pressure without removing the valve or breaking into the line, keeping stem-seal upkeep to minutes rather than a shutdown.
Where It's Used
- Gas, liquid, or fibrous: The XS150 handles gas, liquids, and fibrous slurries, making it a versatile isolation valve for pulp and paper, mining, and general heavy process service.
- Stringy and solids-laden media: The unrestricted straight-through bore passes media that would bridge or erode a reduced-port valve.
- Clean gate, full bore: Dual scraper blades and gate guides keep the gate clean without reducing the flow area.
- Universal yoke: The yoke accepts handwheel, bevel gear, chainwheel, cylinder, or electric actuation with a standard open and closed lockout.
Good to Know
- Standards and patterns: The valve is built to recognized pressure-class and face-to-face standards, with a short-pattern option available.
- Stainless or carbon body: Bodies come in a stainless steel S series or a carbon steel R series, with gate material to suit.
- Flexible flange drilling: Standard flange drilling covers common layouts, and DIN and custom bolt patterns are available.
- Elastomer is the variable: The seal elastomer, EPDM, Viton, or Aflas, is the main selection variable, chosen for the service temperature and chemistry.
- Designed for tough duty: If your line sees reversing flow, dead-end conditions, or frequent cycling, this is the knife gate designed for exactly that duty.
