2822型直动式二位二通比例阀 burkert

类型描述

直动式比例阀 2822 可被作为调节元件应用于过程调节，适合技术真空状态。通过专门的设计将摩擦和粘滑效应最小化，进而获得一个理想的测量间隔、可再现性以及反应灵敏度。阀门受直流电或高频 PWM 信号的控制。输入信号为零时，阀门会在弹性阀座密封件的作用下密封关闭。该种阀门几乎没有运行噪音，因此特别适合医疗用途。

Type 2822 - Direct-acting 2/2 way Solenoid Control Valve

Type Description

The direct-acting proportional valve Type 2822 can be used as a control valve for process control and is suitable for technical vacuum. A special design minimizes frictional and stick-slip effects and provides an excellent span, repeatability and sensitivity. The valve is driven either by DC or by a high frequency PWM signal. With the input signal at zero, it closes tightly owing to an elastomer seatseal. Because of its almost silent operation, the valve is specially suitable for medical applications.

（1）Excellent dynamics and turn-down ratio
