Praise for control valve contract performance

A Severn Glocon product story
Edited by the Engineeringtalk editorial team Sep 24, 2001

Severn Glocon has been praised for its performance in the supply of specialised severe service control valves to a Middle East oil production platform

The order involved the replacement of three large (10" x 18") blowdown- to-flare angle valves during a field shutdown programme performed by the Abu Dhabi Marine Operating Company.

The severe nature of the application demanded a high technology design solution, which was achieved by the use of Severn Glocon's multi labyrinth trim (MLT) design.

The MLT replaces a conventional concentric cage valve seat design with a computer designed disc stack that presents a multi-stage pressure/multi-path labyrinth flow path to the fluid.

The design enables the MLT to be precisely sized to control energy dissipation and velocity by means of passageways incorporating both axial and radial directions.

The valves supplied to Adma-Opco were designed with 34 stages of pressure let down in their MLT trims.

In spite of the high level of technology and precision inherent in the design and manufacture of these valves, Severn Glocon was able to meet and exceed the fast track production schedule imposed by the contract.

These efforts and the close co-operation exhibited by Severn Glocon staff in the UK and it's newly opened office in Abu Dhabi has been acknowledged by Adma-Opco's acting facilities engineering manager on the project.

Congratulating the company he said: "Your professional attitude and co-operation has been most appreciated and resulted in these critical path items contributing to an improved field shutdown schedule and early restart of oil production".
