Internal pressure is only part of a subsea valve specification. Consider the external environment, materials and operating interface together. Explore ball, check and needle valves, including ROV-operated configurations.
Internal design pressure and external hydrostatic pressure are defined as separate design conditions.
ROV bucket, receptacle, torque, access and intervention geometry are defined for remote operation.
Body, trim, bolting, coating and corrosion requirements are selected for fluid and seawater exposure.
Seat and stem sealing, external pressure and project testing are reviewed as one subsea system.
Define weld-end preparation, pup-piece material, schedule and required length together with any transition details needed to integrate the valve into the subsea piping.
Where double block and bleed or cavity management is required, define venting, draining and pressure-relief philosophy so trapped volumes are handled intentionally.
Specify project qualification, hyperbaric or functional testing, material traceability and documentation requirements early so they are built into the manufacturing route.
Filter by valve type, material or connection.
Provide design pressure, water depth, temperature and fluid composition. Include the operating interface, torque requirements, materials and the project test specification.
