TA-Luft: Low Emissions Ball Valves

  • Item #: TALuftLEBV

Product Description

In March of 2007 A-T Controls received TA-Luft Low Emission certification for broad range of valves with a patented Pyramidal Stem Seal system. At that time fourteen different TRIAC series valves with the live-loaded packing system passed the TA-Luft standard that was established by the German TUV agency (Technischer Uberwachungs-Verein). 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. TRIAC valves can reduce fugitive emissions and lost product by 99% or more compared to legacy control valves. A-T is excited to offer such a range of valve choices to help industries in their drives to reduce emissions.

The TRIAC TA-Luft certified valves employ a unique live-loaded pyramidal stem packing system. This features a patented 45° pyramidal stem and stem seal with Belleville washers and PTFE chevron style 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 Control's product literature identifies each valve model carrying the TA-Luft certification with a green logo.
