Features
- Uninterrupted gasket surfaces help eliminate problems associated with seat retaining screws in the gasket surface and allows use of standard spiral wound gaskets.
- Unique interference seat design with energized elastomer O-ring allows bi-directional ANSI Class VI shut-off at lower pressures. The seat is further energized by line pressure, providing the same tight bi-directional shut-off at full-rated pressure.
- Heavy duty circular key holds the seat and retaining ring in place, providing bi-directional, dead-end service at full-rated pressure. This helps eliminate the need for easily corroded and hard-to-remove retention screws.
- Valve stem designed to API 609 standards is blow-out resistant.
- Seat retaining ring is housed within the flange gasket ID to eliminate potential emission path.
- Face-to-face conforms to MSS SP-68 and can be configured to ISO 5752 short.
- Adjustable packing utilizes unique rocker-shaped gland bridge that compensates for uneven adjustment of gland nuts.
- Extended neck allows for two inches of clearance for insulation.
