High Pressure Ball Valves
High-pressure ball valve selection is driven by pressure class, forged or cast construction, seat load, cavity pressure behavior, RTJ/BW ends and actuator torque.
Define the operating envelope before selecting the valve construction.
High-pressure ball valve selection is driven by pressure class, forged or cast construction, seat load, cavity pressure behavior, RTJ/BW ends and actuator torque.
Base valve construction still matters
After the service condition is defined, select the underlying floating, trunnion mounted, top entry, fully welded or DBB design according to size, pressure, maintenance access and isolation duty.
Information to include in the RFQ
Include pressure class, line size, body material, RTJ/BW requirements, seat arrangement, maximum differential pressure and actuator requirements in the RFQ.
Key design questions for high pressure ball valves.
Use these points to define the project design envelope and qualification requirements.
Class 900 / 1500 / 2500
Specify the required size, pressure class, design pressure/temperature and project material class.
Forged Pressure-Containing Parts
Define forging grades, heat-treatment and NDE requirements where they are controlled by the project specification.
RTJ / Butt Weld Ends
Provide flange or weld-end details, wall thickness and piping-class requirements for interface review.
Seat Load & Actuation
Provide maximum differential pressure, operating philosophy and actuator requirements so seat load and operating torque can be reviewed.
Technical documents for project review.
For technical evaluation, request the applicable product documents and inspection records for the offered valve configuration.
Product Photos
Additional finished-valve, nameplate and component photos are available for the selected valve configuration.
GA Drawing / Datasheet
GA drawings and datasheets are prepared for the selected size, pressure class and valve configuration.
Testing & Inspection Records
Inspection documentation can include pressure testing, dimensional inspection, PMI, NDE/NDT and coating records as required by the project.
