进口对夹式气动球阀附件选项： 

根据不同控制和要求可选择下列附件： 

回讯器：也叫限位开关，远程反馈开关信号(可选防爆)。 

电磁阀：双作用选二位五通、单作用选二位三通(可选防爆)。 

三联件：可对气源稳压、过滤、气缸加润滑油。 

手轮机构：转动手轮机构，可实现手动开、关阀。 

电气定位器：输入4～20mA信号,实现阀门调节功能。

The following accessories can be selected according to different control and requirements:

Feedback device: also called limit switch, remote feedback switch signal (optional explosion-proof).

Solenoid valve: double acting two position five way valve, single acting two position three way valve (explosion proof).

Triplet: it can stabilize the pressure of air source, filter and add lubricating oil to cylinder.

Handwheel mechanism: turn the handwheel mechanism to open and close the valve manually.

Electric positioner: input 4 ~ 20mA signal to realize valve regulation function.
