Norvalves design DNV compliant

As part of a recent supply to one of our customers they required a design verification report to be carried out by DNV GL on our current 2” metal seated 690 bar ball valve design.

The review was completed and we are pleased to announce that our design which is already fully qualified to ISO 13628-4 was found to comply with their Offshore Standard DNVGL-OS-E101 “Drilling facilities”, January 2018.

The standard covers drilling systems and equipment located both surface and subsea, including wellhead connectors.

The objective of this standard are to provide an internationally acceptable standard of safety and reliability for drilling facilities, by defining minimum requirements for design, manufacturing, installation and testing of such facilities.
Serving as a guideline for designers, manufacturers, purchasers, owners, contractors and operators.


Our designs are fast track and cost competitive but we never compromise on engineering excellence or quality
