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