Dresser Masoneilan Smart Valve Interface II Advanced Performance

April 2009 Vol. 236 No. 4

Dresser Masoneilan along with joint venture partner DS Control Technologies in Novgorod, Russia, say they have demonstrated a new benchmark in large-valve positioner accuracy.

Proving the Dresser Masoneilan Smart Valve Interface II Advanced Performance (SVI® II AP) positioner’s robust capabilities and versatile configurability, it controls a 56-inch by 36-inch by 56-inch, ANSI 150 measurement AST ball valve.

The valve is the largest in a natural gas compression station designed by contractor Kukdumalakgaz in Uzbekistan, Central Asia. The double-acting positioner delivers a .3% valve control accuracy rate, a rate above the average of 1-3% for this type of application. 972-361-9800, www.dresser.com.
