“Quick Advance” (QA) sampling valves offer “ease of use” in collecting truly representative samples. The QA valves employ a rack and gear combination that provides a full piston motion while the handle only travels one-third of a turn. Valve design also reduces dead space to eliminate the need to purge the valve prior to collection. The valve line is compliant with international standards and is available in a range of materials. — Strahman Valves Inc., Bethlehem, Pa.
