The 68 series proportional solenoid valve is designed for energy-efficient and quiet control of gases, with a flow rate of up to 160 l/min air. It is suitable for high-quality requirements in medical and analysis technology. The valve's compact and cost-effective design allows for easy integration into existing applications, with options for customization to meet specific customer needs.

• Compact design
• Cost efficiency
• Flexible customization

For optimal performance in proportional applications, a valve-specific PWM control with additional dither is recommended.
