Metering valves are designed to provide accurate and stable control of flow rates in analytical, instrumentation, and research applications. A variety of connection sizes, body patterns and materials of construction provide considerable application versatility. Precisely tapered valve stem accurately controls flow. It can be panel or in-line mounted. It also has positive handle to stop preventing over tightening. Valve stem threads are not in contact with process fluid. Metering valve dispensing head eliminates uneven clutch application times that result in dot diameter variations. Employing software controlled direct drive technology; head provides the most precise dispensing of multiple dot sizes with one spindle, and multiple dot combinations between spindles. The too less design minimizes cleaning time and simplifies both operation and maintenance. It offers excellent flexibility in dot size and material range, and is the perfect choice for high- ix/high change over.
