253B排气节流阀的主要特点如下:
1、253B型排气节流阀用来调节工艺系统中的气体排放，通过一个舌门来调整气体的流量，从而控制工艺过程的压力.
2、253B型的舌门轴和马达驱动轴之间有一个独特的非线性激励器，用来产生线性的阀门切换特性并提供平滑的线性压力控制.
3、253B型有各种标准的尺寸和法兰类型，它与所有MKS系列节流阀控制器兼容.
Type 253
The MKS Type 253 Exhaust Throttle Valve regulates the removal of gas from a processing system. Its flapper is positioned to modulate gas flow, thereby controlling process pressure. The 253 has a non-linear actuator placed between the flapper shaft and the motor drive shaft in order to generate a linear valve transfer characteristic and provide smooth linear pressure control. The MKS Type 253 is available in standard sizes and flange styles, and is compatible with all MKS throttle valve controllers.
