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。

电磁阀应在电源电压为额定电压的15%-10%波动范围内正常工作;
电磁阀安装后,管道中不得有反向压差。
并需通电数次,使之适温后方可正式投入使用;
AC: 32˚F to 125˚F (0˚C to 52˚C) Red-Hat II DC: 32˚F to 104˚F (0˚C to 40˚C) Red-Hat
DC: 32˚F to 77˚F (0˚C to 25˚C) (104˚F/40˚C occasionally)
- 238910 238914 Standard Voltages: 24, 120, 240, 480 volts AC, 60 Hz (or 110, 220 volts AC, 50 Hz). 6, 12, 24, 120, 240 volts DC.
Must be specified when ordering. Other voltages available when required.
原理:通电时,电磁线圈产生电磁力把关闭件从阀座上提起,阀门打开;
断电时,电磁力消失,弹簧把关闭件压在阀座上,阀门关闭。
Approvals: CSA certified. Red-Hat II meets applicable CE directives.
Standard: Red-Hat II - Watertight, Types 1, 2, 3, 3S, 4, and 4X; Red-Hat - Type I. Optional: Red-Hat II - Explosionproof and Watertight,
但功率较大,要求必须水平安装。
电磁阀安装前应彻底清洗管道。通入的介质应无杂质。阀前装过滤器;
Types 3, 3S, 4, 4X, 6, 6P, 7, and 9; Red-Hat - Explosionproof and Watertight,
Types 3, 4, 4X, 7, and 9. (To order, add prefix “EF” to catalog number,
特点:在零压差或真空、高压时亦能可*动作,
当电磁阀发生故障或清洗时,为系统继续运行,应安装旁路装置。
except Catalog Numbers 8210B57, 8210B58, and 8210B59.Valves not available with Explosionproof enclosures.)
Valve Parts in Contact with Fluids
Features • Wide range of pressure ratings, sizes, and resilient materials provide long service life and low internal leakage.
• High Flow Valves for liquid, corrosive, and air/inert gas service.
特点:在真空、负压、零压时能正常工作,
但通径一般不过25mm。
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,

当入口与出口达到启动压差时,通电后,电磁力先导小阀,
• Industrial applications include: - Car wash
- Laundry equipment - Air compressors - Industrial water control - Pumps
Pilot Operated General Service Solenoid Valves Brass or Stainless Steel Bodies 3/8" to 2 1/2" NPT
Nominal Ambient Temperature Ranges: Red-Hat II/ Red-Hat
安装时应注意阀体上箭头应与介质流向一致。
不可装在有直接滴水或溅水的地方。电磁阀应垂直向上安装;
