Floating Ball Valves

TECHNICAL FEATURES

FLOATING BALL DESIGN

DESIGN

Floating Ball valves are manufactured in three main types; One piece End Entry Type. Two Piece Bolted Construction. Three Piece Bolted Construction. Valves can be supplied Full or Reduced Bore and are manufactured in either cast or forged construction. Bolted and Screwed Body connections give ease of service and maintenance on site. Valves can be supplied with either Raised Face, Ring Type Joint, Socket Weld or Screwed End connections. Pressure rating is from ANSI 150 thru ANSI 2500. Higher pressures can be supplied on request. Valves are supplied with Lever or Gear Operator.

MATERIAL SELECTION

Valves are manufactured in a range of materials such as Carbon Steel, Low Temp Carbon Steel, Stainless Steel, Duplex, Super Duplex, Monel, Inconel and other Special Alloys.

BODY/CAP SEAL

Graphite rings, O rings or PTFE Seals guarantee perfect sealing between Body and Cap. The Graphite ring continues to provide a seal in the event of a fire. O rings can be supplied suitable for AED applications.

SEAT

Valve seat design provides a perfect seal with various materials in both high and low pressure applications.

STEM

Stems are manufactured separately from the Ball, and incorporate O Rings, Graphite rings and Anti-static devices.

BALL

Balls are supplied in Forged or Cast Stainless Steel, Duplex or Carbon Steel with ENP.

TESTS

Valves are tested in accordance with BS EN 12266, API 6D, API 598 and ASME B16.34

FIRE TEST CERTIFICATION

Valves are designed and certified by an Independent Authority according to API 607 and API 6FA.

EXTERNAL COATING

Carbon Steel valves are normally supplied with KVC standard paint finish. Valves can also be supplied unpainted or to customers paint specification.

ACCESSORIES

Include locking devices, pipe pups, extended bonnets and actuators. Suitable materials, components, seats and O rings can be supplied for valves with Anti Explosive Decompression, Low Temperature/High Temperature or Cryogenic applications.
