Subsea Outlet Check Valves

TP Asker Subsea has more than 25 years of experience with design and manufacturing of Subsea Outlet Check Valve for the oil and gas industry.

All engineering and production is performed inhouse at one location.

One of our main assets is that with overall modern facilities, we have the flexibility to provide short lead time for our products, which are all machined, assembled and tested according to industry standards.

The Outlet/Check Valve is designed for operations like control of flow lines during pigging operations. The outlet valve may be installed in series to form a double barrier. The valve is manufactured and tested according to ISO 10423/API 6A.

Most of these products may be refurbished and reused; please see the “Refurbishment” section for more information about this service.
