Ball Valve - Type 32000 | Ibor Valves

Ibor Type 32000 Ball Valve

The Ibor 32000 is a 2-way ball valve used for on/off isolation in industrial liquid and gas pipelines. The design includes a self-relieving seat arrangement to vent excess pressure from the ball cavity when trapped fluid expands thermally.

Technical Characteristics

• Self-relieving seat for cavity pressure relief
• Stem extension or bonnet extension for insulated lines or buried/remote installations
• Fugitive-emission-oriented stem sealing design, subject to selected packing arrangement
• Locking device for valve position control
• Drain plug for cavity draining, depressurisation, or sampling duties
• Hard overlay on the seat area or on all wetted parts, depending on erosion/corrosion duty
• Heating or cooling jacket for temperature-sensitive fluids

End Connections and Standards

• Flanged ends: ASME B16.5, GOST 12815-80, or EN 1092-1
• Socket weld ends: ASME B16.11
• Butt weld ends: ASME B16.25
• NPT threaded ends: ASME B1.20.1
• BSPP or BSPT threaded ends: BS 21

Typical Applications and Media

Typical services include steam distribution, hot water circuits, process gases, hydrocarbons, condensate, utility air, nitrogen, and general industrial fluids compatible with the selected body, trim, and seat materials.

The drain plug is used where the cavity must be drained or depressurised before maintenance. This is relevant on thermal cycling duties, hydrocarbon service, and lines where trapped pressure may remain after upstream and downstream isolation.

Operating and Selection Notes

• Pressure class, temperature range, and pressure-temperature rating shall be checked against the selected body material, seat material, and flange standard.
• Self-relieving seats reduce the risk of cavity overpressure caused by thermal expansion of trapped liquid.
• Jacketed construction is selected for viscous fluids, crystallising media, waxy hydrocarbons, or services requiring controlled cooling.
• Overlay or hardfacing is considered where erosion, corrosion, or frequent operation affects the seat contact area.
• Material certificates such as EN 10204 3.1, PED compliance, ATEX suitability, or NACE/ISO 15156 requirements should be specified when required by the project.

Actuation Options

• Manual lever for smaller sizes and accessible locations
• Gear operator for larger sizes or high operating torque
• Pneumatic actuator for automated isolation and interlock systems
• Electric actuator for remote operation in utility or process control systems
• Hydraulic actuator for high-torque or critical shutdown duties

Sealing Options

Seat and packing selection depends on fluid chemistry, temperature, pressure class, cycling frequency, and leakage requirement. Soft-seat, reinforced polymer-seat, or metal-seat executions should be confirmed against the manufacturer’s data for the specified service.

Variant Differences

• Flanged version: preferred for removable pipeline installation and maintenance access.
• Welded version: used where external leakage paths must be minimised.
• Threaded version: suitable for smaller utility lines, subject to pressure and vibration limits.
• Extended stem or bonnet: used on insulated, cryogenic, high-temperature, or buried services.
• Jacketed version: used where process temperature must be maintained around the valve body.

FAQ

Why is a self-relieving seat used?
It allows pressure trapped in the ball cavity to relieve to the pipeline side, reducing overpressure risk during temperature increase.

Can the valve be automated?
Yes. Selection of actuator type depends on torque, stroke time, control philosophy, hazardous area classification, and available utilities.

What must be checked before ordering?
Line size, pressure class, temperature, medium compatibility, end connection standard, seat material, leakage class, certification, and maintenance access.
