Ball Valve - Type 36001 | Ibor Valves

Ibor Type 36001 Ball Valve

The Ibor 36001 is a 2-way ball valve used for flow isolation in industrial piping. It is specified for clean liquids and gases where tight shut-off, bidirectional service and controlled cavity pressure are relevant to valve selection.

Sealing and Body Design

• Self-relieving seat for cavity pressure relief in closed-valve conditions.
• Bidirectional shut-off, subject to the selected seat arrangement and pressure direction.
• Secondary soft seat for additional sealing where low leakage is required.
• Stem thermal extension or bonnet extension for insulated lines, hot service or operator clearance.
• Design provisions for fugitive emission control at the stem packing area.
• Locking device for open/closed position control.
• Drain plug for cavity draining, depressurisation or maintenance checks.
• Hard overlay on the seat area or all wetted parts for corrosive or erosive duties.
• Heating jacket option for viscous fluids or media with solidification risk.

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.
• Threaded NPT ends: ASME B1.20.1.
• BSPP or BSPT threaded ends: BS 21.

Typical Applications and Media

Typical services include steam distribution, hot water circuits, thermal oil, hydrocarbons, process gases, utility gases and auxiliary process networks. Media should be compatible with the selected body material, seat material, stem packing and any overlay specification.

Operating Conditions

Pressure class, temperature limit and allowable differential pressure shall be checked against the manufacturer datasheet, valve size, body material and seat configuration. For high-temperature service, verify stem extension, packing material and insulation clearance. For viscous or crystallising fluids, evaluate the heating jacket and drain arrangement.

Actuation Options

• Manual lever for smaller sizes and low operating torque.
• Gear operator for larger sizes or higher differential pressure.
• Pneumatic actuator for on/off control and interlocked isolation.
• Electric actuator for remote operation in utility or process systems.

Variant Selection

• Use flanged ends where periodic removal is expected.
• Use butt weld or socket weld ends where permanent welded installation is preferred.
• Use threaded ends mainly on smaller bore utility lines.
• Specify overlay for abrasive, corrosive or seat-wear-sensitive service.
• Specify secondary soft seat where leakage class is a controlling requirement.

FAQ

What is the function of the self-relieving seat?
It limits pressure build-up in the body cavity when trapped fluid expands due to temperature increase.

When is a heating jacket required?
It is considered for heavy hydrocarbons, waxy fluids, resins or media that may thicken or solidify when cooled.

Is the valve suitable for throttling?
No. This type is primarily an isolation valve. Continuous throttling can damage seats and increase leakage.
