FAT of 18 ESDV ball valves near completion

Ringo Válvulas is completing the Factory Acceptance Test (FAT) of the last valves out of the eighteen (18) ESDV top entry ball valves for top riser to be supplied for several offshore platforms in the North Sea to Maersk Oil (Denmark). Some of the valves were already dispatched and some of them are already under painting and packing process.

The order includes pneumatic and hydraulic operated valves although shipment of valves is going to be performed with an installed gear box in each valve, as per contract specifications.

Since these valves have a critical safety function and have to fulfill an extraordinarily high level of requirements, it was a challenge for Ringo to make the design and manufacturing of them. The high safety factor to size the actuators at the minimum air supply combined with the maximum actuator torque (MAT) at the maximum air supply made Ringo to find a suitable solution for the shaft with a MAST enough to withstand the MAT by means of manufacturing this part from a material used from aerospace industry.
