vwe1602_Duesseldorf_tm01_cmyk01More than 600 exhibitors from around the world will be showcasing their products at Valve World Expo 2018, the 11th International Valve Trade Fair & Conference (www.valveworldexpo.com), which is taking place at the Düsseldorf fairgrounds November 27–29. The exhibition, which is organized by Messe Düsseldorf GmbH (Germany; www.messe-duesseldorf.de), will encompass 194,000 ft2 in three halls of the fairground.

The exhibits will be complemented by the Valve World Conference 2018 in Hall 4, with expert talks and workshops by international speakers. In addition, the Pump Summit will be held in Hall 5, featuring state-of-the-art pump technologies and the latest results from science and research. Acting as an interface between valve and fitting technologies, the Pump Summit will provide a valuable addition and create important synergies for visitors.

What follows is a small selection of products being exhibited.

A new approach for severe-duty microflow valve

A new, patent-pending approach for microflow control is based on a (rotary) sliding gate valve (photo), where two slices with lapped surfaces are installed in the valve, pressed together by a spring and the differential pressure. This enables zero-tolerance, without any limitation due to tolerances or thermal expansion. Each slice has one or more bores for the flow passage. Normally, the flow passage of such a sliding gate valve is only open when the bores overlap. Especially with small rated flow coefficient (that is, small bores), this results more or less in an on/off characteristic of the valve. In this new design, one of the slices is equipped with a tangential flow channel, which leads and expands into the bore of this slice. This enables a smooth control behavior with sufficient opening angle (more than 60 deg). The slices can be made of any material (even ceramics), which makes the trim resistant against each process fluid and pressure drop. Although the valve plug movement is quarter-turn, a standard globe-valve housing DN 15–25 (ANSI½ to 1 in.) rated PN16–PN 250 (ANSI Class 150 – 1500) is used. This makes the design economic and allows changing from a standard valve to the new design, even at an existing valve, says the manufacturer.
