REXROTH力士樂(lè)電磁閥是用電磁力作用于密封在電動(dòng)調(diào)節(jié)閥隔磁套管內(nèi)的鐵芯完成，不存在動(dòng)密封，所以外漏易堵絕。電動(dòng)閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚至拉斷閥桿頭部；電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏，直至降為零。所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。
REXROTH力士樂(lè)電磁閥特點(diǎn):
1 ,士樂(lè)電磁閥電磁閥和全不銹鋼;對(duì)于強(qiáng)腐蝕的介質(zhì)必須選用隔離膜片式。中性介質(zhì),也宜選用銅合金為閥殼材料的電磁閥,否則,閥殼中常有銹屑脫落,尤其是動(dòng)作不頻繁的場(chǎng)合。氦用閥則不能采用銅材。
2、性環(huán)境:必須選用相應(yīng)防爆等級(jí)產(chǎn)品,露天安裝或粉塵多場(chǎng)合應(yīng)選用防水,防塵品種。
3、電磁閥公稱壓力應(yīng)超過(guò)管內(nèi)Z高工作壓力。
