6221 2/2-Way Solenoid Valve
Brand: Burkert Fluid Control SystemsThe 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.
Features- High lifetime also under pulsed conditions
- Solutions for rough air applications
- High reliability
- Compact design with high flow rates
- Modular solenoid coil system different sizes and power ratings
- Low noise
- Easy coil change
- Coil can be locked in 4x 90º positions, or move freely between, as required
- Wide range of cable plug options Type 2508
