Inspection

Inspector Detail

Common issues

  • Seat leakage from soft seat wear or damage by cargo residue/scale
  • Ball surface scoring from solids in the cargo or poor line flushing
  • Stem seal/packing leakage after repeated cycling
  • Actuator-to-valve coupling wear (remote-operated units) causing position indication errors
  • Corrosion at the valve-to-tank flange where cargo tank coating has broken down
  • Difficulty achieving full closure due to seat contamination

Inspection checklist

  • Function-test full open/close travel and confirm position indication matches actual ball position
  • Check for external leakage at stem packing and body joint
  • Leak-test seat tightness per the vessel's tank valve testing schedule
  • Inspect actuator linkage and limit switches (remote-operated units)
  • Check flange bolting and gasket condition
  • Verify the valve operates without excessive torque
  • Confirm valve tag/line identification matches the cargo system drawing

Service intervals

Seat/seal renewalcondition-based on leak test results, typically reviewed at each dry-docking
Stem packing adjustment/renewaltypically every 1-3 years depending on cycling frequency
Full valve overhaultypically at dry-docking intervals (2.5-5 years) - confirm against class/PMS requirement
Actuator service (if fitted)per the actuator maker's own schedule

Typical wear limits

Seat leakage acceptanceassessed against the vessel's/charterer's approved tank valve tightness test criteria rather than a fixed physical dimension

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Soft seat set (ball seats)
  • Stem seal/packing set
  • Body gasket
  • Ball, if scored beyond repair
  • Stem O-rings

Safety

  • Cargo tank valves are part of the tank isolation boundary - confirm correct isolation and venting before maintenance
  • Residual cargo/vapour may remain in the valve body - follow gas-freeing and permit-to-work procedures
  • Stored energy in spring-return actuators must be released before disassembly
  • Verify seat/seal material compatibility with the actual cargo carried before ordering replacements

Class survey

Cargo tank valves are examined as part of tank/cargo system surveys; class and terminal inspections commonly require documented valve tightness/leak test records and isolation valve function tests at intervals set by the vessel's PMS and class rules.

Estimated lifetime: Valve bodies of this type typically remain in service for the life of the vessel with periodic seat and seal renewal; a fixed operating-hour life is not meaningful for a manually cycled cargo valve.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
