用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。

Types 3, 3S, 4, 4X, 6, 6P, 7, and 9; Red-Hat - Explosionproof and Watertight, 

Types 3, 4, 4X, 7, and 9.  See footnote on next page. 

斷電時，先導閥利用彈簧力或介質(zhì)壓力推動關閉件，向下移動，使閥門關閉。

 Special AC and DC constructions are available to pilot power plant control valves.

Standard Coil and Class of Insulation

Watt Rating and Power Consumption Spare Coil Part Number

General Purpose Explosionproof

電磁閥可以配合不同的電路來實現(xiàn)預期的控制，

Features ?   Designed for high flow and high pressure service. 

?   Direct acting, requires no minimum operating pressure. 

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。

 Red-Hat - Type 1. Optional: Red-Hat II - Explosionproof and Watertight, 

而控制的精度和靈活性都能夠。

 Consult your local ASCO sales office for details.

Approvals: CSA certified. Meets applicable CE directives. Refer to Engineering Section for details.

Standard: Red-Hat II - Watertight, Types 1, 2, 3, 3S, 4, and 4X; 

常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等

原理：它是一種直動和先導式相結(jié)合的原理，當入口與出口沒有壓差時

?   Ideal for power plants and similar applications.

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。

- 224195 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. 

Note: 125 and 250 volts DC are battery voltages applied in power plants.

?   Choice of metal seating materials to handle aggressive fluids, or resilient seating for airtight shutoff.

當入口與出口達到啟動壓差時，通電后，電磁力先導小閥，

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；、
