6281 EV – servo-assisted diaphragm valve Pulse coils The brass version of the valve is suitable for controlling neutral liquids and gases in pressure and vacuum applications. Available connections include G and NPT as well as DIN flanges. Pulse coil versions are the ideal solution for applications with low requency f switching. The switching process is achieved by a short electrical pulse. A permanent magnet ensures that the valve opens. The benefit is the low power consumption and the low heat development in the valve. This p revents the formation of scales in the valve, which means...

6281 EV – servo-assisted diaphragm valve Irrigation / sprinkler systems In greenhouses or open fields, pipes with process connections from ½" to 2" are used for irrigation and sprinkling. The water pressure is between 2 and 6 bar and the free outlet of the pipe achieves a constant sufficient differential pressure between the valve inlet and outlet. The servo-controlled 6281 EV valve is a reliable and cost-effective solution for this application. Drinking water and foods Drinking water and food applications place special requirements on the media-contacting materials of the valves. Body...

6213 EV - spring coupled servo-assisted diaphragm valve The spring coupled 6213 EV servo-assisted diaphragm valve was developed for controlling liquids and gases. The spring coupling causes partial opening of the main valve at a differential pressure of nearly zero bar. The special HP00 version is available for safety-related requirements or special requirements for opening and closing. Regional and industry-specific certifications and options are also available, which makes it easier to choose the right valve. The following table gives an overview of the available versions. The following...

6213 EV – spring coupled servo-assisted diaphragm valve Safety shut-off valve in accordance with DIN CERTO The brass version of the valve is suitable for controlling neutral liquids and gases. Dezincification-resistant brass, nickel-plated brass and tainless s steel are available as additional body materials. The last two are free of non-ferrous metal, which makes them ideal for applications with mildly acidic and alkaline solutions. The available standard process connections are G and NPT threaded. This version is tested and approved in accordance with DIN EN ISO 23553‑1 as a safety...

6213 EV – spring coupled servo-assisted diaphragm valve Electrode cooling of welding robots Welding electrodes in welding robots used in continuous operation have to be cooled to prevent the electrode from burning and to extend the service life. This is achieved by water-cooling through a econdary pipe. Water is pumped into the cooling circuit at a pressure of 4 –10 bar, depending on s the electrode. The valve diameter can range from 1/2" to 2", depending on the welding system. Shut-off valves for oil supply systems Oil fired systems are supplied with fuel oil via corresponding supply...

290 EV - fixed coupled servo-assisted diaphragm valve Overview of versions and properties The fixed coupled 290 EV servo-assisted diaphragm valve was developed for reliable switching with liquids and gases starting at a differential pressure of zero bar. The core guide tube is extrusion coated and the powerful coil system features epoxy resin encapsulation. Different certifications and certificates are available depending on the application and the regional utilisation of the valve. Additional technical versions offer customised solutions. The following table gives an overview of the...

290 EV – fixed coupled servo-assisted diaphragm valve Soft-kick function for large diameters This fixed coupled valve is suitable for controlling liquids and gases with a differential pressure starting at zero bar. The valve features a soft-kick function to increase the service life. In small diameters up to DN 25 an elastomer ring serves as an additional damping element between the core and the main diaphragm. In larger d iameters, this function is performed by an additional spring. Both ensure soft oupling of the main diaphragm during the opening process. The diac phragm is opened in a...
