Type 2657...59 DN 10 up to 80 mm; Plastic; 2/2 way dvantages/benefits ntegrated pilot valves, position feed-back and limit switches available Customized system solutions with Burkert valves & sensors With S-bus interface - Namur valves as pilots available Design/Function pplications The ball valve family type 2657...59 is designed for any kind of application in the process industry. The ball valve consists of two variable modules, the valve body and the actuator. This two-piece valve body is available in, and plastic material. The quarter turn for opening the valve can be done by a hand lever, by a pneumatic actuator or by a compact high performance electric actuator, depending on the application and on the kind of control of the process. ts modular concept allows to build up a ball valve for any degree of automation and any kind of application in the process industry. system can be completed with pilot valves for the operation of the pneumatic actuator, a compact position feedback, a Control Head, optional with S-bus, for ON/OFF control functions. n Easy Link can be built up with any kind of sensor. The electric motor actuator has a standard signal input (4...20 m) to be connected and controlled directly by a PLC. Fluids Neutral gases and liquids Ultra-pure fluids Highly aggressive fluids Slightly contaminated liquids pplications Drinking water distribution Water treatment / ozoning systems Slow processes / tank farming in beverage and pharmaceutical industry Shut-off armatures in chemical and dyeing industry Textile machines Cleaning machines Galvanic and etching processes Fluid Control Systems
