Parker assumes no liability for damage caused by improper material selection.Caution: Do not, at any time, make any alteration or modifications to any valve without the express and written approval of Parker’s Fluid Control Division.DESCRIPTIONThese valves are 3-way direct operated valves. The 304 series valve product line are available as Normally Closed (N.C.), Normally Open (N.O.), or universal (U) valves. The direct acting valves operate with zero pressure differential.Valves may be ordered with either NEMA 2, 4, 4X integrated coils for ordinary locations. Additional solenoid coils and enclosures are offered as described in our catalog.FLUID CODESListed below are the common fluid codes. The codes for the approved fluids for use with each valve are printed on the outside of the individual packaging.CODE FLUIDA - Air or nontoxic, nonflammable gasesAC - AcetyleneG - City gas supplied by public utilieisGA - GasolineHO - Petroleum based oils having viscosities up to 400SSU at 38°F02 No1 and No 2 fuel oils with viscosities lessthan 40SSU at 38°COX - OxygenW Water or other aqueous nonflammable liquidsFor the maximum fluid temperatures, as well asvalve ambientlimitations, check the valve part number on the nameplate and refer to the catalog.TORQUE CHARTINSTALLATION INSTRUCTIONS Installation must be done according to all applicable Safety Codes and Standards and by qualified personnel.Inspect valve prior to installation. Damaged valves oractuators must not be installed.Mounting position and pressure limits: Valves can bemounted directly on piping or by using the two #8-32 UNF threaded holes in the bottom of the valve body for the 1/8” NPT valves. Two #10-32 UNF threaded holes for the 1/4” NPT valves. The valves are designed to operate in any position. The valve may be installed in any line regardless of the direction in which the line runs. However, for optimum life and performance, the valve should be mounted vertically upright so as to minimize wear and reduce the possibility of foreign matter accumulating inside the sleeve area. Line pressure, voltage and frequency must conform to nameplate rating. Allow adequate clearance above valve for removal of coil. WARNING: Do not install a valve whose permitted pressure / temperature ratings are inadequate to meet the operating conditions. Piping: Remove protective closures from the ports. Connect line pressure to the inlet port and apparatus piping to the outlet port. Use of Teflon™ tape, threaded coumpounds or sealants is permissible but should be applied sparingly to male pipe threads only. CAUTION : Do not allow foreign particles, Teflon tape, or thread compound to enter valve. Only the wrench flats provided on the body ports should be used in applying the torque. Ports should not be subjected to excessive torque by use of an oversized wrench, wrench extension or by impacting the wrench handle. Do not use the valve to “stretch” or “align” the pipe. Tightening torque should not exceed 100 in-lbs for 1/8” NPT valves and 175 in-lbs [20,0 Nm] for 1/4” NPT valves. Do not use sleeve or enclosure as a lever when applying torque.Media filtration: For protection of the valve, install a suitable strainer or filter in the inlet side as close to the valve as possible. Dirt or foreign material in the media may cause excessive leakage, wear, or in exceptionalcases, malfunction. Clean periodically depending on service conditions. Lubrication: Lubrication is not required although air linelubrication will substantially increase valve life. Electrical connection: Electrical supply must conform to nameplate rating. Connect coil leads or terminals to the electrical circuit using standard electrical practices in compliance with local authorities and the National Electrical Code. Do not power coil until it has been fitted over sleeve and the retaining nut has been installed to prevent possible coil damage from overheating. WARNING : Turn off electrical power before connecting the valve to the power source. If the coil assembly is located in an inconvenient orientation, it may be reoriented to facilitate installation. Loosen coil assembly nut, rotate coil assembly to desired position, then retighten the retaining nut with an input torque per chart. COIL ASSEMBLY Position coil (as described below) on the sleeve, position and tighten retaining nut into the top of the sleeve assembly using a 5/32” or 5mm hex wrench with an input torque per chart. If the coil orientation needs to be repositioned to meet installation wiring needs, simple loosen the retaining nut usi ng a 5/32” or 5mm hex wrench , then rotate the coil to the required position and tighten the retaining nut. NOTE : The one-piece integrated coil assembly contains top and bottom o-ring seals to prevent moisture ingressioninto the sleeve area. The o-ring seals must be installed correctly for proper functionality. PORT MARKING ARRANGEMENTDe-Energized Energized11 33333One-Piece Integrated Coil.

三位五通电磁换向阀的工作原理
第一次听说有一种电磁换向阀叫“三位五通”，请问：它的结构与工作原理是什么请真正的内行回答。

不要回答那些诸如“二位三通”、“二位四通”之类文不对题的东西。

问题补充：
三位五通电磁换向阀如何实现在动作的过程中停止我讲的“在动作的过程中停止”是指通过电磁阀的控制作用使气缸能在行程中的任意位置上停止，而不是仅指气缸在中间位置上停止。

请行家进一步指教。

最佳答案
三位五通顾名思义，三个工作位置，五个口。

三个位置是指电磁阀的阀芯有三个位置。

三位电磁阀都是有两个线圈的。

我们暂且称之为A和B线圈。

AB都不通电的时候阀芯是一个位置，A通电时阀芯会动作，这是第二个位置，A断电，B通电的时候阀芯的位置是第三个位置。

所以一共三个位置。

请注意三位五通电磁阀有三种，指AB都不通电的时候阀芯的状态不同分为中封，中开和中闭。

你可以看下面的图片现实的是中闭型三位五通阀。

五通就是指五个口，一个进气口，两个气缸口，两个排气口（这两个也可以并成一个）。

补充：如何在动作中停止很简单，就是电磁阀两边全部断电，阀芯在中间位置，如果是中闭的话（就是把气缸两头进气通道堵住），这样气缸两头无法排气就会使气缸停在中间，无法动作，但是由于气缸，电磁阀会有泄露，通常这样无法长时间停在准确位置。

阀的种类及图例目录阀门的分类 (3)我国目前大多数习惯是按压力和结构种类来区分 (3)按结构种类分主要有： (3)旋塞阀、闸阀、截止阀、球阀 (3)止回阀（包括底阀） (3)节流阀 (3)蝶阀 (3)安全阀 (3)减压阀 (3)疏水器 (4)按用途和作用分类 (4)截断阀类 (4)调节阀 (4)止回阀类 (4)分流阀类 (4)安全阀类 (4)按压力分类真空阀——工作压力低于标准大气压的阀门。

(4)低压阀 (4)中压阀 (4)高压阀 (5)超高压阀 (5)按介质温度分类高温阀——t 大于450'C的阀门。

(5)中温阀 (5)常温阀 (5)低温阀 (5)超低温阀 (5)金属材料阀门 (5)金属阀体衬里阀门 (5)通用分类法 (6)气动调节阀 (6)电动调节阀 (9)自力式调节阀 (11)电磁阀 (12)球阀 (13)蝶阀 (15)闸阀 (17)截止阀 (19)止回阀 (20)旋塞阀 (22)柱塞阀 (22)隔膜阀 (23)减压阀 (24)安全阀 (25)疏水阀 (26)排气阀 (27)排泥阀 (28)呼吸阀 (29)防腐衬氟阀门 (30)在现场我们见到最多的就是阀。

汽包液位三冲量控制、锅炉的燃烧控制等，都是通过阀门开度和关度的大小来控制对象，我们通过算法的目的也是要控制阀门开度和关度的大小，从而达到自动控制。

阀门的用途是广泛的，因此它起的作用也是很大的。

例如：在发电厂中阀门能够控制锅炉和汽轮机的运转；在石油、化工生产中，阀门同样也起着控制全部生产设备和工艺流程的正常运转。

尽管如此，阀门同其它产品比较往往被人们忽视。

例如：在安装机器设备时，人们往往把重点放在主要机器设备方面，如：压缩机、高压容器、锅炉等，这些做法都会使整个生产效率降低或停产、或造成种种其它事故发生，所以我们有必要对阀门进行认识和了解。

阀门的分类阀门产品的种类繁多，说法也不完全统一，有的按用途分（如化工、石油、电站等）、有的按介质分（如水蒸汽、空气阀等）、有的按材质分（如铸铁阀、铸钢阀、锻钢阀等）、有的按连接形式分（如内螺纹、法兰阀等）、有的按温度分（如低温阀、高温阀等）。
