SMC具有固定節(jié)流孔和急速供氣機(jī)能的速度控制閥SSC（ASS）作用

在中泄式電磁閥驅(qū)動(dòng)氣缸的回路中，當(dāng)中泄閥處于中位時(shí)，氣缸活塞兩側(cè)都排空。當(dāng)換向閥切換至左位時(shí)，因無桿腔很快充氣，有桿腔初始時(shí)為大氣壓力，故活塞桿會(huì)急速伸出傷人或損壞設(shè)備。若將無桿側(cè)的排氣節(jié)流式速度控制閥改裝成固定節(jié)流孔和有急速供氣機(jī)能的速度控制閥（SSC系列），則可避免上述活塞桿急速伸出事故。

SMC 具有固定節(jié)流孔和急速供氣機(jī)能的速度控制閥SSC（ASS）的使用注意

1）SSC閥應(yīng)安裝在防止活塞桿急速伸出的供氣側(cè)，希望直接誒裝在氣缸上。若與氣缸用配管連接，一旦配管長(zhǎng)，不僅速度控制變差，在正常動(dòng)作時(shí)，其始動(dòng)作時(shí)間也變長(zhǎng)，甚至速度控制不起作用。
2）100mm以下短行程氣缸及擺動(dòng)氣缸不要使用SSC閥。
3）負(fù)載率在50%以下使用SSC閥，以免正常動(dòng)作時(shí)的速度控制不起作用。
4）排氣節(jié)流控制的SSC閥，防止活塞桿急速伸出的初始速度是不可調(diào)節(jié)的，若希望低于初期速度且可調(diào)，則應(yīng)選用進(jìn)氣節(jié)流控制的SSC閥（ASS110·310）。
5）缸內(nèi)有殘壓的回路，使用進(jìn)氣節(jié)流式的速度控制閥就能防止活塞桿急速伸出。
