Class 150 Ball Valves
Class 150 Ball Valves are used for general process, utility and pipeline isolation at lower ASME pressure ratings. Use this specification range to match the requirement to the correct ball valve construction, seat system, material combination, end connection and project testing scope.
Class 150 Ball Valves: what to confirm before quotation.
Class 150 Ball Valves are grouped by pressure class rather than by a single valve construction. The correct valve can be floating, trunnion mounted, top entry, fully welded or DBB depending on the service.
Pressure class is only one part of the valve selection
A Class 150 ball valve must still be checked against design temperature because pressure-temperature capability depends on material group and the governing design code. Body construction, flange or weld ends, seat system and actuator torque must match the actual design envelope.
Class 150 Floating Ball Valve for the intended duty
For general process, utility and pipeline isolation at lower ASME pressure ratings, trunnion construction is often considered as size and pressure increase, while floating designs remain practical for suitable smaller sizes. Higher classes can favor forged construction, RTJ or butt-weld ends, and more detailed review of seat load, cavity relief and operating torque.
RFQ data for Class 150 ball valve
Send the applicable valve and piping specifications together with service medium, design pressure and temperature, line size, valve class, materials, end connection, operation and inspection requirements. This allows the manufacturer to avoid assumptions that can cause technical deviations later.

Class 150 Ball Valves FAQ
What valve designs are available as a Class 150 ball valve?
Depending on the project, the requirement can be combined with floating, trunnion mounted, top entry, fully welded or double block and bleed valve construction.
What information is needed to quote a Class 150 ball valve?
Provide valve type, size, pressure class, material requirements, end connection, design pressure and temperature, media, operation, test requirements and the applicable project specifications.
Is Class 150 floating ball valve a separate valve design?
It combines the named specification with a valve construction or application. The final design still depends on the complete datasheet.
