Features and Benefits
- High-integrity, tight shut-off performance in both upstream and downstream directions in severe services ensured by robust thermoplastic soft-seat and expanding gate design
- Greater longevity due to expanding gate design that reduces seal wear during opening and closing strokes
- Improved reliability provided by a unique internal control arm mechanism that unlocks the gate and segment from the expanded, closed position without requiring additional seals
- Reduced body and seat deflection due to engineered body structure that maximizes strength and stiffness while minimizing weight
- Lower installation costs and broader application flexibility with compact, lightweight design that can fit into confined spaces
