01
Pipeline isolation
API 6D ball valve selection is organized around pressure class, bore, material, fire-safe requirements, testing and project documentation.
02
High-pressure isolation
Gate valve profiles focus on pressure-seal or wedge construction, body and trim materials, end connection, inspection and MDR requirements.
03
Severe-service systems
Butterfly, alloy and cryogenic profiles connect temperature, corrosion, sealing, actuation, testing and export packaging to the RFQ.
