ASCO TRI-POINT switches are available in either a
general purpose or watertight enclosure, in addition to
open frame construction. These enclosed units are
made in accordance with NEMA and UL standards.
These standards define the protection level an
enclosure gives and the tests it must pass to meet
particular design.
General Purpose – Type 1. These enclosures are
ASCO阿斯卡直動(dòng)式電磁閥高溫流體：要選擇采用耐高溫的電工材料和密封材料制造的電磁閥，而且要選擇活塞式結(jié)構(gòu)類(lèi)型的。
3、美國(guó)ASCO阿斯卡直動(dòng)式電磁閥流體狀態(tài)：大至有氣態(tài)，液態(tài)或混合狀態(tài)，特別是口徑大于DN25訂貨時(shí)一定要區(qū)分開(kāi)來(lái)。
4、流體粘度：通常在50cSt以下可任意選擇，若超過(guò)此值，則要選用高粘度電磁閥。

三、美國(guó)ASCO阿斯卡直動(dòng)式電磁閥根據(jù)壓力參數(shù)選擇電磁閥的：原理和結(jié)構(gòu)品種
1、美國(guó)ASCO阿斯卡直動(dòng)式電磁閥公稱(chēng)壓力：這個(gè)參數(shù)與其它通用閥門(mén)的含義是一樣的，是根據(jù)管道公稱(chēng)壓力來(lái)定。
2、美國(guó)ASCO阿斯卡直動(dòng)式電磁閥工作壓力：如果工作壓力低則必須選用直動(dòng)或分步直動(dòng)式原理；低工作壓差在0.04Mpa以上時(shí)直動(dòng)式、分步直動(dòng)式、先導(dǎo)式均可選用。
designed for indoor use to protect personnel from
accidental contact with the equipment. P-Series
general purpose enclosures are painted, zinc-coated
steel and have a 7/8” diameter hole at the top for
electrical entry.
Watertight – Type 4.Watertight and dust-tight
enclosures are intended for use indoors and outdoors
to protect the enclosed equipment against splashing or
falling water, windblown dust and water, hose directed
water, and severe external condensation. P-Series
watertight switch enclosures are epoxy-painted, zinccoated
steel with a 1/2” conduit hub in the side of the
lower housing for electrical entry. (For optional 316 SS
watertight enclosure see page 13.)
