Ball Valve - Type 36002 | Ibor Valves

Ibor Type 36002 Ball Valve

The Ibor 36002 is a 2-way ball valve used for industrial isolation service in liquid and gas lines. The valve includes a self-relieving seat arrangement to relieve pressure from the ball cavity when trapped fluid expands thermally.

Seat Design and Cavity Relief

• Self-relieving seat / cavity relief design.
• Reduces the risk of cavity overpressure caused by thermal expansion of trapped media.
• Applicable for open/closed isolation duty; not intended for continuous throttling or modulating flow control.
• Seat and seal material selection shall be checked against fluid compatibility, pressure class, and operating temperature.

Stem, Leakage Control, and Maintenance

• Available with stem or bonnet extension for insulated lines, elevated temperatures, or access constraints.
• Stem sealing design suitable for fugitive-emission control requirements where specified by the project.
• Locking device available for position control and maintenance safety procedures.
• Drain plug permits cavity draining, depressurisation, or flushing before maintenance.

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.
• Integral nipples are available for socket weld and butt weld executions.

Typical Applications and Media

• Steam and condensate isolation, subject to pressure-temperature rating and seat material limits.
• Hot water, compressed air, process gases, lubricating oil, hydrocarbons, and plant utility services.
• Process lines where tight shut-off and low pressure drop in the fully open position are required.
• Isolation upstream or downstream of equipment, manifolds, skids, and utility headers.

Variant Selection

• Flanged valves are preferred where periodic removal, inspection, or replacement is expected.
• Socket weld and butt weld versions are used on permanent process pipework where leakage at joints must be reduced.
• Threaded versions are generally selected for smaller bore utility lines and non-critical services.
• Manual lever, gear operator, pneumatic actuator, or electric actuator selection depends on valve size, differential pressure, cycle frequency, and site automation requirements.

FAQ

• Can it be used for throttling? No. It is intended for isolation service; partial opening can damage seats and create unstable control.
• Why specify a self-relieving seat? It allows pressure trapped in the ball cavity to relieve, reducing thermal expansion risk in closed valve conditions.
• Which connection is easiest to maintain? Flanged construction allows removal without cutting the pipe. Welded versions provide a more permanent joint.
