TA-Luft Certified for Low Emissions - Ball Valves

A-T Controls Receives TA-LUFT Low-Emission Certification for Wide Family of TRIAC Valves with Patented Stem Sealing

TA-LUFT Documentation

March 2007 - A-T Controls, next-day supplier of ball valves, actuators, controls and packaged solutions for process industries, has received TA-LUFT low-emission certification for its broad range of direct-mount valves with patented pyramidal stem seal system. Fourteen different TRIAC series valves with the live-loaded packing system passed the TA-LUFT standard established by the German TUV agency (Technischer Uberwachungs-Verein), said Brad Mueller, A-T Controls president. Considered the world's most stringent standard on valve emissions, TU-LUFT testing requires less than 1 ppm leakage through the valve stem.

"Fugitive valve emissions are a major environmental and economic issue for process industries," said Mueller. "Our TRIAC valves can reduce fugitive emissions and lost product by 99% or more compared to legacy control valves. We are excited at being able to offer such a range of valve choices to help industries in their drives to reduce emissions."

The TRIAC valves employ a unique live-loaded pyramidal stem packing system, said Mueller. This features a patented 45° pyramidal stem and stem seal with Belleville washers and grafoil stem packing, protecting against stem leaks experienced with ordinary ball valves.

The TRIAC valves also feature a patented automation pad that allows direct mounting of ISO5211-compliant actuators to eliminate the cost and fabrication of special couplings or brackets. A-T Controls offers pre-assembled valve/actuator packages shipped ready for installation, typically on one-day turnaround.

A-T Control's new catalog and web site identify each valve model carrying the TU-LUFT certification with a green logo.
