Saudi Aramco is the latest end user to take delivery of high technology Severn Glocon MLT control valves to fulfil especially demanding applications.
Severn Glocon is supplying two 16 by 24in Class 300 control valves for hydrocarbon sour gas to flare duties at the Saudi Aramco Uthmaniyah installation in the country's eastern province.
The valve duty involves sour gas flowing at up to 14.8ft3/h at a pressure of 238lb/in2(a).
Each valve is designed to reduce the pressure to just under 60in2(a), a ratio of 4:1 that would require the equivalent of six conventional concentric cages in a traditional globe valve design.
By adopting the Severn Glocon MLT alternative solution, concentric cages are replaced by a far more compact multilabyrinth trim, consisting of a stack of computer designed discs that offer multiple stages of pressure let down.
For this specific application, the MLT stack, manufactured from 316 grade stainless steel and Stellite coated, has been designed with 12 stages of pressure reduction and fitted within a completely new valve pattern.
Both valves will be equipped with double-acting pneumatic actuators, smart positioners and side-mounted handwheels.
The order for Aramco was received from the Saudi contractor ZATE by Severn Glocon's established agent in the country, YBA Kanoo, who will provide local support for the installation.
