主閥下腔壓力上升,上腔壓力下降,從而利用壓差把主閥向上推開;
斷電時,先導閥利用彈簧力或介質壓力推動關閉件,向下移動,使閥門關閉。
2/2 SERIES 8262 8263
Nominal Ambient Temperature Ranges: AC: 32?F to 125?F (0?C to 52?C) DC: 32?F to 104?F (0?C to 40?C)
Approvals: CSA certified. UL listed, as indicated. Normally Closed Valves FM approved. Meets applicable CE directives.
在關 閉件周圍形成上下高的壓差,
流體壓力推動關閉件向上移動,閥門打開;
斷電時,彈簧力把先導孔關閉,入口壓力通過旁通孔迅速腔室
在關閥件周圍形成下上高的壓差,

302 Stainless Steel Shading Coil Copper Silver Stem PA (Normally Open) Note: All 1/8" NPT Normally Open valves contain CA.
All 1/4" NPT Normally Open valves contain PA.
電磁閥從閥結構和材料上的不同與原理上的區別,分為六個分支小類
油用電磁閥、直流電磁閥、高壓電磁閥、防爆電磁閥等。
Brass 303/304 Stainless Steel Seals and Discs
當入口與出口達到啟動壓差時,通電后,電磁力先導小閥,
Standard Coil and Class of Insulation
? Mountable in any position.
? Brass body construction for general atmospheres; Stainless Steel for corrosive atmospheres.

直動膜片結構、分步直動膜片結構、先導膜片結構
特點:在零壓差或真空、高壓時亦能可*動作,但功率較大,要求必須水平安裝。
原理:通電時,電磁力把先導孔打開,上腔室壓力迅速下降,

6, 12, 24, 120, 240 volts DC. Must be specified when ordering. Other voltages available when required.
原理:它是一種直動和先導式相結合的原理,
當入口與出口沒有壓差時,通電后,電磁力直接把先導小閥
和主閥關閉件依次向上提起,閥門打開。
Features ? Reliable, proven design with high flows.
? Small poppet valves for tight shutoff.
? Wide range of elastomers for specialty service.
液體電磁閥、微型電磁閥、脈沖電磁閥、液壓電磁閥 常開電磁閥、
Standard: Watertight, Types 1, 2, 3, 3S, 4, and 4X. Optional: Explosionproof and Watertight,
Types 3, 3S, 4, 4X, 6, 6P, 7, and 9. (To order, add prefix “EF” to catalog number)
