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.
先导式电磁阀,通电时,依靠电磁力提起阀杆,导阀口打开,
? Mountable in any position
Pilot Operated Quick Exhaust Solenoid Valves Brass or Stainless Steel Bodies 1/4" and 3/8" NPT
断电时,在弹簧力和主阀芯重力的作用下,阀杆复位,
先导孔关闭,主阀芯向下移动,主阀口关闭;
电磁阀上腔压力升高,流体压力向主阀芯加压,密封更好。                    
Brass 304 Stainless Steel Seals and Disc NBR (PA upper disc for 8317 Series) Diaphragm CR (8317 Series only) Core Tube          
305 Stainless Steel Core and Plugnut    430F Stainless Steel Core Springs      
302 Stainless Steel and 17-7 PH Stainless Steel Shading Coil   Copper Silver Pilot Seat Cartridge and Disc-Holder CA (8321 Series only) Piston     
在压力差的作用下,流体压力推动主阀芯向上移动将主阀口打开;
and other similar components must be installed in the cylinder lines only.
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 the catalog number.) See Optional Features Section for other available options.

使用流体  水、过滤空气(给油或不给油)、液体、轻油、液态瓦斯  
本体材质  锻黄铜或USU316不锈钢
动作方式  先导式
Nominal Ambient Temp. Ranges AC: 32?F to 125?F (0?C to 52?C) DC: 32?F to 104?F (0?C to 40?C) Refer to Engineering Section for details.
保护型膜片结构设计,寿命延长两倍。
此时电磁阀上腔通过先导孔卸压,在主阀芯周围形成上低下高的压差,
? Multi-industry applications
配管方式可以任意角度安装,为增强寿命最好是水平管接线圈朝上。
线圈防护等级IP65。
AC General Purpose Explosionproof
 Approvals CSA certified. UL listed General Purpose Valves. Meets applicable CE directives. Refer to Engineering Section for details.
 Important A Minimum Operating Pressure Differential must be maintained between the pressure and exhaust ports.
 Supply and exhaust piping must be full area, unrestricted. ASCO flow controls
适用介质:液体、水、热水、气体、油、瓦斯等
Standard Coil and Class of Insulation
Watt Rating and Power Consumption Spare Coil Part Number
3/2 SERIES 8317 8321
Features ? Designed for quick venting to 0 psi through the exhaust orifice
? Resilient seated poppets for tight shutoff
零压差或自流状态的介质,小通径一般选用直动式电磁阀;
阀前后存在压力差,大通径则选用先导式电磁阀。
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。
先导膜片式结构,低功能。
 Brass and 303 Stainless Steel (8321 only)
