The Shut-Off Metering Ball Valve Series delivers industry’s highest degree of accurate metering flow for moderate pressure applications. The MBV series features an innovative and unique shut off capability which allows full control of the process from extra fine regulation to a complete valve shut off. The choice of three precision stem tapers enables metering at flow capacities as low as Cv=0.0001 with up to 11 handle turns, the MBV series meets the high demand of precise flow control. With the option of five O-ring materials the MBV series provides the best temperature and chemical coverage, making it ideal for the Oil & Gas analyzing industries.

In oil refining and petrochemical industries,where researchers develop industrial processes to enhance the efficiency of the production, new product quality standards, especially concerning environmental issues, are necessary to achieve these goals. The main technical challenge is the need to support high pressure and high temperature fluid operation. Vinci Technologies Company, located in Paris, France, is a designer and manufacturer of analytical pilot plants, laboratory equipment and specific field instrumentation for the Oil & Gas Industry. Vinci Technologies relies on Ham-let’s comprehensive range of valves and fittings, they have chosen to implement the new, innovative MBV series design. into their Catalyst Testing Unit. The MBV series offers major advantages over the traditional instrumentation solutions: from cost efficiency, reduced installation time & labor, smaller system footprint and minimizing potential leak points.
