主阀下腔压力上升,上腔压力下降,从而利用压差把主阀向上推开;
断电时,先导阀利用弹簧力或介质压力推动关闭件,向下移动,使阀门关闭。
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.
在关 闭件周围形成上下高的压差,
流体压力推动关闭件向上移动,阀门打开;
断电时,弹簧力把先导孔关闭,入口压力通过旁通孔迅速腔室
在关阀件周围形成下上高的压差,

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.
电磁阀从阀结构和材料上的不同与原理上的区别,分为六个分支小类
油用电磁阀、直流电磁阀、高压电磁阀、防爆电磁阀等。
Brass 303/304 Stainless Steel Seals and Discs
当入口与出口达到启动压差时,通电后,电磁力先导小阀,
Standard Coil and Class of Insulation
• Mountable in any position.
• Brass body construction for general atmospheres; Stainless Steel for corrosive atmospheres.
Direct Acting General Service Solenoid Valves Brass or Stainless Steel Bodies 1/8" to 3/8" NPT
直动活塞结构、分步直动活塞结构、先导活塞结构。
电磁阀按照功能分类:水用电磁阀、蒸汽电磁阀、制冷电磁阀、
温电磁阀、燃气电磁阀、消防电磁阀、氨用电磁阀、气体电磁阀、

直动膜片结构、分步直动膜片结构、先导膜片结构
特点:在零压差或真空、高压时亦能可*动作,但功率较大,要求必须水平安装。
原理:通电时,电磁力把先导孔打开,上腔室压力迅速下降,

6, 12, 24, 120, 240 volts DC. Must be specified when ordering. Other voltages available when required.
原理:它是一种直动和先导式相结合的原理,
当入口与出口没有压差时,通电后,电磁力直接把先导小阀
和主阀关闭件依次向上提起,阀门打开。
Features • Reliable, proven design with high flows.
• Small poppet valves for tight shutoff.
• Wide range of elastomers for specialty service.
液体电磁阀、微型电磁阀、脉冲电磁阀、液压电磁阀 常开电磁阀、
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)
Valve Parts in Contact with Fluids Body
流体压力推动关闭件向下移动,关闭阀门。
特点:流体压力范围上限较高,可任意安装(需定制)但必须满足流体压差条件。
