Sub Sea Valves

Our Sister company Maverick Valves Manufacturing HQ manufactures complete integrated units of subsea valve, actuator and ROV receptacle tool.

With a very strong Quality Assurance and Engineering Dept., MVM HQ is able to design and manufacture the most specific and customized actuated valves according to the project requirements.

Subsea Valves and actuators are critical components of any offshore installation.

Any subsea intervention is costly, time-consuming and extremely difficult, and any

failure would result in loss of profit for the Operators and End Users.

Type of applications

  • Pipeline subsea valves
  • Subsea Manifolds
  • Line tees for future tie-ins
  • Jacket flooding valves
  • SSIV (Sub Sea Isolation Valves)
  • PLEM ESDV and On/Off Valves
  • Semi-submersible Buoy and Turret

Type of valves used in subsea environments

Ball Valves

  • Generally Piggable type, they are used normally in subsea pipeline
  • Possibility of Seat design metal to metal with tungsten carbide coating.
  • Corrosion Resistant Alloys on valve dynamic sealing parts and ring joint grooves
  • Redundant sealing, for increased reliability of the valve

Through Conduit Slab and Double Expanding Gate Valves

  • They are used normally in subsea manifolds or pipelines when there are fluid mixes of liquid, gas, and sand.
  • The valve design is suitable for a high percentage of sand or solid particles
  • inside the fluid and very high pressure (normally above 5000 psi)
  • Thanks to their Through Conduit Design, they are fully Piggable.
  • Possibility of Seat design metal to metal with tungsten carbide coating.
  • The Double Expanding Gate Valves are used when a DB&B is required for isolating the downstream cavity

Check Valves

  • Piggable type, they are used normally in subsea pipelines
  • On request, they can be provided with Override Tool (ROV Operable) for allowing Piggability of both sides
  • The Valves are operated by the types indicated in “Types of Operators”

Type of operators

Shallow water (normally down to 75 meters water depth)

  • by Diver
  • by ROV receptacle tool
  • remotely by Hydraulic Actuators with or without ROV receptacle tool / Hand-wheel override

Deep water (normally down to 3500 meters water depth)

  • by ROV receptacle tool
  • by Hydraulic actuators with or without ROV receptacle tool override in case of hydraulic failure

Main standards

  • API 17D/ISO 13628-4 (Specification of subsea equipment and wellhead equipment)
  • API 17A/ ISO 13628-1 (Design and Operation of Subsea Production Systems)
  • API 17H/ ISO 13628-8 (Remotely Operated Vehicle (ROV) interfaces on subsea production systems)
  • API 6DSS/ISO 14723 (Specification on Subsea Pipeline Valve)
  • ISO 10423 (drilling and production equipment)
  • Norsok –U-001 (subsea production system)
  • Norsok – L-001 (piping and valves)
  • Norsok – M-001 (material selection)


Subsea valves and actuators are tested and inspected in accordance with:

  • ISO 10423
  • API 6A (at PSL Level)

Some other types of test (other than the standards for the above-surface valves and actuators) are:

  • Gas testing according to API 6D / API 6A PSL 3G
  • Performance verification test according to API 6A PR 2
  • Hyperbaric testing
  • Bending calculation and test
  • Seismic test
