Construction Details
BODY / CAP
Sealing is by O-rings and Graphite ring continues to provide a seal in the event of a fire. O-rings can be supplied suitable for AED applications in a variety of materials.
SEAT
Independent seats with preloaded springs are always in contact with the Ball to protect the seal even at low pressure. Replaceable Seat rings and soft inserts can be supplied in materials to suit most service conditions. For very high temperatures, sealing is ensured by metal to metal seats (Tungsten carbide coated). Most sizes and classes have a sealant injection system fitted as standard.
STEM & BALL
Stems are manufactured separately from the ball and feature an anti-blow-out design. They are supported by RPTFE lined bushes to reduce torque. Sealing is by O-rings and graphite rings. Balls are supplied in Forged or cast Stainless Steel, Duplex or Carbon Steel with ENP. The Trunnion Mounted design reduces operating torque and seat wear.
