Ball Valve - Type 32005 | Ibor Valves

Ibor Type 32005 Ball Valve

The Ibor 32005 is a 2-way ball valve used for flow isolation in industrial liquid and gas piping. The self-relieving seat arrangement allows pressure trapped in the ball cavity to be discharged to the line, reducing the risk of cavity overpressure. The bidirectional design permits installation for flow in either direction, subject to the piping specification and valve marking.

Sealing, Drainage and Maintenance Features

• Self-relieving seat / cavity pressure relief
• Bidirectional sealing arrangement
• Stem sealing injector for in-service sealant injection where specified
• Locking device for mechanical position control
• Drain plug for cavity drainage or depressurisation
• Nipple and needle arrangement for drain, vent or sampling service
• Overlay on the seat area or on all wetted parts for erosive or corrosive media
• Heating jacket for fluids requiring temperature maintenance

End Connections and Standards

• Flanged ends: ASME B16.5, GOST 12815-80 or EN 1092-1
• Butt weld ends: ASME B16.25
• Integral nipples where required by the line arrangement
• Pressure class, face-to-face dimensions, materials and testing requirements should be checked against the project valve datasheet

Typical Applications and Suitable Media

The valve is applied in steam, hot water, thermal oil, hydrocarbons, fuel gas, process gas and general utility service. Heating jackets are used when the medium must remain above a minimum temperature to avoid viscosity increase, solidification or wax deposition.

Operating and Selection Considerations

• Select body and trim materials according to corrosion allowance, chloride content, sour service requirements and operating temperature.
• Seat and seal materials define the allowable temperature range and leakage class.
• For liquids with thermal expansion risk, the self-relieving seat reduces pressure build-up in the closed valve cavity.
• For maintenance planning, consider access to stem injection, drain plug and nipple/needle connections.
• For automation, confirm torque at differential pressure before selecting pneumatic, electric or hydraulic actuators.

Variant Differences

• Standard isolation version: used for clean liquids and gases where cavity drain is not routinely required.
• Drain or vent version: used where depressurisation, sampling or flushing is part of the operating procedure.
• Overlay version: used for abrasive, erosive or corrosive duties affecting the seating area or wetted surfaces.
• Heating jacket version: used for viscous hydrocarbons, bitumen-like fluids, oils or media sensitive to cooling.

FAQ

Can the valve be installed in either flow direction?
Yes, the design is bidirectional, but installation should follow the project piping class and valve documentation.

Why is cavity relief important?
Liquids trapped in the closed ball cavity can expand with temperature. A self-relieving seat provides a controlled relief path to the line.

Which actuator types can be used?
Manual lever or gear operation is typical. Pneumatic, electric or hydraulic actuators may be selected when remote operation, interlocking or process control integration is required.
