功能

• 2/2 Proportional Flow Control Valve -2871 Series
• The Burkert proportional solenoid valve is capable of continuously adjusting and smoothly controlling the flow rate of the passing liquid. Unlike conventional solenoid valves and process valves that only provide on/off control, the Burkert 2871 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 grade
• Plunger valve actuator
• Response time:; 15 ms
• Power Consumption: 5 W
• PWM Frequency: 1500 Hz
• Continuous Rated Duty Cycle: 100%
• Repeating Accuracy: Less than 0.25% 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.
