Additional primary energies: Upstream

We are specialists in upstream operations, from subsea to surface projects, where we provide solutions with the most advanced technologies.

The upstream industry includes searching for potential underground or underwater crude oil and natural gas fields, drilling exploratory wells, and subsequently operating the wells that produce and boost the crude oil and raw natural gas to the surface.

AMPO, as a reference supplier for the industry, has being involved since 1964 in the design and production of highly engineered solutions for the upstream sector, supplying the most critical and tough application demanded valves for:


AMPO POYAM VALVES are suitable for subsea production and transportation systems, which refers to all the equipment and structures located on or below/buried in the seafloor for the production of oil or gas from, or for the injection of fluids into, a field under an offshore production site. This includes: production risers, flow lines, and associated production and transportation control systems.

The basic and essential function of a subsea production and transportation system is to control the production and transportation of fluids, providing a means to technically and economically produce remote and/or deepwater reserves by placing wellheads and associated mechanical and electrical infrastructure on the sea bed.


AMPO POYAM VALVES can be installed in the following units:



Connected by risers to the Pipeline End Manifold (PLEM)


  • Wells
  • Xmas Trees
  • Manifolds/ Templates & Connections systems
  • Control Systems


  • Pipelines
  • Subsea Isolation Valve (SSIV) stations
  • Pipeline End Manifold (PLEM)
  • Export Riser Bases (ERB)
  • Pig Traps
  • T- and Y-stations


AMPO POYAM VALVES holds recognized API certificates such as API6DSS, API17D and API6A for the design and manufacturing of highly engineered valves for this critical industry. We have likewise successfully completed a wide range of industry standards and qualifications.

AMPO POYAM VALVES are suitable for surface operations that may include oil and gas extraction and treatment, storage and offloading, process support systems, etc. All valves in a topside construction must be suitable to perform in the hostile environments experienced in most cases at sea or in coastal locations. Topside constructions must be able to cope with a full range of extreme conditions from arctic cold, to high-temperature and pressure applications in the gas treatment process.

AMPO POYAM VALVES can be installed in the following units: Platforms, FPSO, FSRU, FLNG, Extraction and Processing Units, etc.


At AMPO POYAM VALVES we have lengthy experience supplying highly engineered valves for topside constructions. Materials such as carbon, low-temperature carbon, stainless steel, duplex, and super duplex as well as nickel alloys are all available. All materials can be supplied to API, ASTM, ASME, ISO, NORSOK, and other international standards.

Our extensive experience partnering with customers to deliver topside valves around the world has enabled us to develop unparalleled expertise in corrosion control as well as to meet application-specific weight and size requirements.

Our management is completely based on the strictest quality standards, as the foundation enabling AMPO POYAM VALVES to develop the product which best satisfies our customers. The standard testing procedure of our topside valves is based on the API 6A/API6D standards.
