Ball Valve - Type 19000 | Ibor Valves

Ibor Type 19000 Ball Valve

The Ibor 19000 is a 2-way ball valve used for on/off isolation in industrial piping systems handling liquids, gases, steam auxiliaries and process utility services. Selection is normally based on pressure class, temperature, fluid compatibility, leakage requirements and cavity isolation philosophy.

Technical Configuration

• DIB I or DIB II seat arrangement for double isolation and bleed requirements
• Seat sealing injector for in-service sealing support where applicable
• Stem sealing injector for stem packing maintenance provisions
• Stem or bonnet extension for insulated lines, buried service or restricted access
• Locking device for open/closed position control
• Coating on the seat area or on all wetted parts, depending on medium and corrosion risk
• Optional heating or cooling jacket for temperature-sensitive fluids

End Connections

• Flanged ends: ASME B16.5, GOST 12815-80, EN 1092-1
• Socket weld: ASME B16.11
• Butt weld: ASME B16.25
• NPT threaded ends: ASME B1.20.1
• BSPP / BSPT threaded ends: BS21

Standards and Certifications

Design may be specified to API 6D / ISO 14313. Face-to-face dimensions follow ASME B16.10 or EN 558-1 Series 27. Top flange is according to ISO 5211 for actuator mounting. Pressure-temperature ratings are based on ASME B16.34. Testing can be carried out to API 6D, API 598 and EN 12266-1.

Available certifications include PED 2014/68/EU, ATEX, Fire Safe API 6FA / API 607 / ISO 10497-2, fugitive emissions Class A according to ISO 15484-2, SIL 2 according to IEC 61508 and NACE MR0175 material compliance for sour service where specified.

Typical Media and Operating Duties

• Steam, condensate, water and utility gas networks
• Hydrocarbon liquid and gas lines
• Chemical and petrochemical process units
• ATEX classified areas
• Lines requiring fire-safe construction or controlled fugitive emissions

DIB I vs DIB II Selection

• DIB I: double piston effect seats; both seats can seal against pressure from either side, including the body cavity.
• DIB II: one double piston effect seat and one self-relieving seat; used where cavity pressure relief logic must be considered.

Actuation and Operation

The ISO 5211 top flange allows manual lever, gearbox, pneumatic, electric or hydraulic actuator installation. Actuator sizing should account for differential pressure, seat material, operating frequency, safety factor and required fail position.

Application Notes

A jacketed body is considered when the process medium must be kept above a pour point, prevented from crystallising, or cooled under controlled conditions. Sealant injection points are maintenance features and should not replace correct seat and packing selection for the service conditions.

FAQ

• When is fire-safe design required? On hydrocarbon, solvent or flammable gas lines where valve integrity after fire exposure is part of the plant safety basis.
• When is NACE MR0175 relevant? For sour service containing H2S where material hardness and corrosion cracking resistance must be controlled.
• What should be checked before procurement? Pressure class, end connection, material, seat type, stem sealing, certification package, actuator interface and leakage class.
