Fabri-Valve OM150

The Fabri-Valve OM150 Urethane Lined Knife Gate Valve provides an economical solution for abrasive and corrosive applications. The OM150 does not discharge process media to the environment. Central to the design of the valve is the most robust perimeter seal in the industry, which provides reliable bi-directional, bubble-tight shutoff.

Each valve is lined with our proprietary urethane material which protects the valve body from the abrasive and corrosive media that the OM150 is designed for. The OM150 body halves are machined to lock in place, the urethane lining that is molded and bonded to each body half. This ensures consistent and repeatable, open and closing gate thrust requirements in any installation. The seal groove is specially designed to prevent seal pull-out but also allows the seal to move and prevent over compression.

Hard Urethane Lining:

  • Body protection from abrasive and/or corrosive media.
  • Mechanically bonded to valve body and is fully supported to prevent lining deflection.
  • Provides seat protection from abrasion of direct process flow impingement.
  • Molded triple scrapers clean gate during operation to protect integral chest seal.

Patented One-Piece Perimeter & Chest Seal:

  • Bi-directional, repeatable shutoff.
  • Zero discharge. Zero leakage.
  • The perimeter seal has shoulders, which locks the seal in the seal groove even during the most demanding applications.
  • Excellent bi-directional shut-off even at very low differential pressure.
  • Chest seal wraps around the entire gate eliminating leakage paths.
  • Chest seal completely encloses injectable packing eliminating contamination of the process fluid by “loose” packing.

Easy Maintenance:

  • Injectable packing allows easy packing adjustments to be made under line pressure without valve disassembly or removal of the valve from the pipeline.
