進口對夾式氣動球閥附件選項： 

根據(jù)不同控制和要求可選擇下列附件： 

回訊器：也叫限位開關(guān)，遠程反饋開關(guān)信號(可選防爆)。 

電磁閥：雙作用選二位五通、單作用選二位三通(可選防爆)。 

三聯(lián)件：可對氣源穩(wěn)壓、過濾、氣缸加潤滑油。 

手輪機構(gòu)：轉(zhuǎn)動手輪機構(gòu)，可實現(xiàn)手動開、關(guān)閥。 

電氣定位器：輸入4～20mA信號,實現(xiàn)閥門調(diào)節(jié)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.
