6221 2/2-Way Solenoid Valve

Brand: Burkert Fluid Control Systems

The valves are based on a modular concept comprising three basic elements: Valve assembly, push-over coil and standard cable plug.

This valve is specifically designed for general-purpose applications with air. 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.

A minimal pressure differential of psi: 14.5 (kPa: 100, bar: 1) is required for complete opening.
