burkert 6221 A 10 13 20 NBR电磁阀The valves are based on a modular concept comprising three basic elements: Valve assembly, push-over coil and standard cable plug. This valve is specificly designed for general purpose applications with air.burkert 6221 A 10 13 20 NBR电磁阀 The design principle of this valve allows high pulsed operations in air pipe runs, where other general purpose valves cannot be used, as they start to vibrate quickly. So life-time of this valve could be substantially increased, compared to other solutions.
