DMN-Westinghouse, Noordwijkerhout, the Netherlands, will at POWTECH be featuring latest versions of its HP high-pressure rotary valves which have recently obtained compliance with the ATEX Directive 2014/34/EU for equipment intended for use in potentially explosive atmospheres. These valves are also pressure shock resistant up to 10 bar g. Moreover, they do not allow any axial air leakage. This means that the valve has an air leakage reduction of one third against other standard high-pressure valves.

 

The HP rotary valves with specially designed inlet are well suited for applications in the metering and pneumatic conveying of dry granular products under a high pressure of maximum 3.5 bar g. The configuration of the body, rotor and seals has been specifically developed to minimise degradation of the product which runs through it, whilst retaining the best possible pocket filling efficiency.

 

Also on display will be the popular MZC rotary valve with sliding bars for easy removal of cover and rotor for inspection and cleaning. The company will present some efficient  improvements to this type of valve as well as several smart servicing solutions. In order to meet the demand for hygienic components, the USDA Dairy Accepted 3-TDV tube diverter, CIP-suitable SBD sanitary ball diverter and SAL small sanitary airlock will also be exhibited. www.dmnwestinghouse.com
