Award winning metering ball valve Ham-Let’s metering ball valve (MBV), which incorporates both metering and shut-off functions in one unit, has been patented in the USA, and has won the company recognition for its innovative technology.

capacities as low as Cv=0.0001 with up to 11 handle turns, the MBV series meets the demand for highly precise flow control. The MBV offers five different O-ring materials providing wide temperature and chemical coverage, making it suitable for analytical instrumentation industries. “The technology used in previous micrometer valves is based on an extremely delicate needle that is easily broken and cannot guarantee that the valve is completely sealed,” said Mr Shestatsky. “In order to hermetically seal a system, the system engineer would have to add a second valve – most commonly a ball valve – to detach and seal the line. This entailed many disadvantages including extra costs, complicated installation, additional pipelines, multiple potential leakage points and more.”

The MBV series valve combines an accurate micrometer control mechanism for gases and liquids with a sealing mechanism in a single unit. It is easy to install and does not require multiple connectors and pipelines. It is reliable and easy to operate, and can reduce the length of the line in the system. The valve is a single unit that replaces the two separate valves previously required, decreasing installation and maintenance costs while reducing the risk of faults. Flow Magazine ’s 2012 winner of innovation award, the MBV was awarded US Patent USPTO 8590569, and patents have also been applied for other markets.
