Valve 6213 EV is a servo-assisted diaphragm valve. The spring coupling of the diaphragm supports the opening process in the valve. In its standard variant, the valve is suitable for deployment with liquids. A minimum differential pressure is required for full opening. For gas and vacuum applications, a special variant is available (HP00) that opens the valve without differential pressure. Various diaphragm materials are available depending on the actual application. The body is is available in brass, stainless steel and gunmetal. For other markets, dezincification-resistant brass is available. To reduce electrical power consumption during operation, coils with integrated Kick-and-Drop (KD) electronics featuring double coil technology are available.
