Features and Benefits •Heavy duty circular key holds the seat and retaining ring in place, providing bidirectional, dead-end service at full-rated pressure. This eliminates the need for easily corroded and hard-to-remove retention screws. •Uninterrupted gasket surfaces eliminate problems associated with seat retaining screws in the gasket surface and allows use of standard spiral wound gaskets. •Laylength conforms to MSS-SP-68 and can be configured to ISO 5752 short for PN25 pressure rating. •Unique interference seat design with energized elastomer 0-ring allows Class VI shutoff at lower pressures. The seat is further energized by line pressure, providing the same tight shutoff at full-rated pressure. •Valve stem, designed to API 609 standards, protects against blow out. •Adjustable packing utilizes unique rocker-shaped gland bridge that compensates for uneven adjustment of gland nuts. Optional non- adjustable packing offers an economical alternative. •Extended neck allows for two inches of clearance for insulation. •Seat retaining ring is housed within the flange gasket I.D. to eliminate potential emission path. •Variety of material trims allows use in various specific applications and services. |
