US110/200 Ultraseal ball valve


One piece reduced bore body, flanged construction in carbon steel, stainless steel and special alloys.

Compact body design with minimum weight and elimination of potential leak path.

Designed in accordance with ASME B16.34, BS EN ISO 17292 and ISO 14313/API 6D.

Floating ball design for bi-directional shut-off.

Flexing soft seat design for superior shut-off across a range of pressures with minimum operating torque.

Low temperature and cryogenic designs for service down to -196°C available on request.

Spring energized metal and carbon seat designs permitting tight shut-off and positive cavity pressure relief.

Fused hard nickel alloy, chromium carbide or tungsten carbide coated seat and ball designs for abrasive and high temperature service.

Hard carbon seat design for medium temperature applications.

High integrity shaft seal minimizing the potential for atmospheric leakage.
