Material Notes:

Ball and stem in 316 Stainless Steel (CF8M) is the standard trim for general industrial service, providing excellent corrosion resistance in water, steam, and oil applications.
For enhanced seawater corrosion resistance and high-pressure service, Monel® K500 ball and stem is available as an optional trim material, suitable for marine, offshore, and mildly sour environments.
Seat material options: PTFE for general applications up to ~200 °C; RPTFE (glass-filled) for improved wear and dimensional stability; PEEK for high-temperature and high-pressure service up to 260 °C.
Actuator mounting flanges to ISO 5211 are available upon request.
External surface finish: sandblasted and degreased as standard.

6. Design Features

Feature Description Benefit
Two-Piece Split Body, Bolted Valve body is split into two main pieces (main body and tailpiece) joined by high-strength bolting and a body gasket. Robust pressure containment; easy disassembly for maintenance; fewer leakage paths than three-piece designs.
Floating Ball Design The ball is not fixed but floats between the seats, pressed against the downstream seat by line pressure. Provides reliable bi-directional sealing; simple construction with fewer parts.
Full Bore (Full Port) The ball bore diameter matches the nominal pipe size. Minimal pressure drop, maximum flow capacity; suitable for pigging applications.
Anti-Blowout Stem Stem is bottom-loaded with an integral shoulder that engages a mating recess in the body. Prevents stem ejection under line pressure, even if the packing gland is removed.
Anti-Static Design Conductive spring or ball between stem and ball ensures electrical continuity. Prevents static electricity buildup; essential for flammable/explosive media service.
Fire-Safe Construction Secondary metal seat backup behind the primary soft seat; graphite stem packing. Maintains sealing integrity during and after fire exposure (API 607 certified).
Bolted Body Gasket Access The split body joint is sealed by a replaceable gasket, accessible by removing the body bolts. Simplifies seat and ball maintenance; reduces downtime.
Lever Handle with Locking Device Standard lever handle with locking provision in open and closed positions. Prevents unauthorized or accidental operation; clear visual open/closed indication.
Corrosion-Resistant Bronze Body ASTM B62 C83600 leaded tin bronze (85-5-5-5) provides excellent resistance to seawater, steam, and mild chemicals. Long service life in marine, industrial, and general-purpose fluid handling applications.
Smooth Surface Finish Sandblasted and degreased external surface as standard. Clean finish free from contaminants, suitable for industrial and marine environments.
