Ball Valve - Type 19002 | Ibor Valves

Ibor Type 19002 Ball Valve

The Ibor 19002 is a 2-way ball valve used for flow isolation in industrial liquid and gas systems. Selection is primarily based on seat sealing philosophy, pipe-end connection, operating media, leakage requirements and maintainability under plant conditions.

Seat Configurations

• DIB I: double piston effect on both downstream and upstream seats. Used where active sealing from both sides of the body cavity is required.
• DIB II: double piston effect on the downstream seat and single piston effect on the upstream seat. Selected where cavity pressure relief behaviour differs between the two seats.
• Seat sealing injector: allows emergency or maintenance sealing assistance at the seat area without immediate valve removal.

Stem, Operation and Leakage Control

• Stem sealing injector for packing support and leakage mitigation during service.
• Stem or bonnet extension for insulated lines, buried service or restricted access areas.
• Fugitive-emissions-oriented design for services where stem leakage must be controlled.
• Locking device for open/closed position control and maintenance safety.

End Connections and Standards

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

Pressure class, bore configuration, body material, seat material and temperature range should be matched to the piping class, corrosion allowance, design pressure, design temperature and media compatibility requirements of the project.

Typical Applications and Media

• Isolation duty in chemical, petrochemical, power and general industrial plants.
• Steam, process gas, water, utilities and hydrocarbon service, subject to material and seat compatibility.
• Battery-limit isolation, pump isolation, equipment bypass lines and maintenance block valves.

Actuation Options

The valve may be specified for manual operation or equipped with an actuator where the valve topworks and torque data allow it. Pneumatic, electric or hydraulic actuation should be selected using break torque, differential pressure, cycling frequency, fail position and area classification.

Variant Selection Logic

• Use DIB I where double active sealing against cavity pressure is required on both sides.
• Use DIB II where controlled upstream/downstream seat behaviour is required for cavity pressure management.
• Specify injectors when online sealing support and reduced intervention time are important maintenance criteria.

FAQ

• Is this a control valve? No. It is intended for on/off isolation, not throttling or modulating control.
• Can it be used on steam? Yes, if pressure class, body material, trim, seats and temperature limits are suitable for the steam conditions.
• What should be checked before procurement? Piping standard, pressure class, end connection, seat type, leakage class requirement, actuator interface, media compatibility and maintenance access.
