功能

• 2/2 Proportional Flow Control Valve -2873 Series
• The Burkert proportional solenoid valve can continuously adjust and smoothly control the flow rate of liquid passing through it. Unlike conventional solenoid valves and process valves that only provide on/off control, the Burkert 2873 series process valves can adjust the flow rate up to 0~ 100% using PWM (pulse width modulation). The design features such as a friction-free valve plunger for very precise adjustment and a highly sealed elastomer seat make this valve ideal for demanding, high-precision control.
• Features and Advantages: Direct motion
• Brass or stainless steel type
• Excellent response time
• Glove valve operating principle
• IP65
• Plunger valve actuator
• Response time:; 20 ms
• Power Consumption: 9 W
• PWM Frequency: 1200 Hz
• Continuous Rated Duty Cycle: 100%
• Repeating Accuracy: Less than 0.5% of Full Scale
• Hysteresis: Less than 5%
• Application: The PWM solenoid control valve is suitable for applications that require finer control of liquid flow than the simple on/off control provided by a standard solenoid valve.
