Valves, Actuators & Pump Control


Valve & Automation supplies valves for Engen project

April 2014 Valves, Actuators & Pump Control

The Engen Back of Berth was implemented to replace the existing 45-year old Durban-Johannesburg pipeline, which was running at full capacity and nearing the end of its design life. To increase the capacity on this critical route and to ensure security of supply for the long term, 555 km of 600 mm (24 inch) pipeline and 160 km of 400 mm (16 inch) pipeline was laid as a hybrid of greenfield and brownfield projects, executed over long distances and difficult terrain that would pose significant cost and delivery problems.

The V&A control solution

The 750 mm (30”) Class 150 Zwick Tri-Con triple offset rotary process valves supplied to Engen as part of this project are fitted with Auma electric actuators. Zwick Tri-Con rotary process valves offer:

* SIL 3.

* Sizes from 2” (DN50) to 88” (DN2230).

* Temperature ratings from -196 to 815°C.

* Zero leakage bi-directional sealing.

* Self cantering temperature compensating disc.

* Quarter turn torque seated.

* Metal to metal seats.

* Inherently fire safe and tested.

* High cycle bearings.
