All De Dietrich® enamelled valves are made of cast steel and lined with our standard DD 3009 glass. Therefore they offer the same properties of chemical corrosion, thermal choc resistances as any other De Dietrich® glass-lined equipment, in particular those of the reactors on which they are installed.

All other parts in contact with the process are made of fluoropolymer (PTFE, PFA). Our valves are available for the following fittings: PN16, ANSI 150 and JIS 10K.

All of our valves are available in manual or pneumatic versions and can be fitted with temperature measurement sensors, measurement electrodes for GlasWatch (appliance for monitoring enamel integrity) and other accessories.

Our valves comply with the requirements of Directive 97/23/EC (PED) and therefore bear the CE marking. They are designed for use with group 1 fluids.

The CleanValve range (CVB)

This range has been designed to satisfy each and every requirement in terms of safety and cleanability. The cleaning opening has been angled at 5° and the outlet nozzle presents a groove to facilite the run-off of the very last drops of product.

The absence of bellows facilitates the cleaning of the valve, especially when the final product is a slurry. The dimensions of the valve bodies in the CleanValve series are interchangeable with all our previous models, which allows them to be fitted instead and in place of the former fittings in an existing installation without having to make any changes to the pipe layout.

De Dietrich CVB valves are TA LUFT certified.

A Fire Safe version has also been produced and can be delivered on request.
