用在工业控制系统中调整介质的方向、流量、速度和其他的参数。

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. 

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。

 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

电磁阀可以配合不同的电路来实现预期的控制，

Features •   Designed for high flow and high pressure service. 

•   Direct acting, requires no minimum operating pressure. 

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。

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

而控制的精度和灵活性都能够。

 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; 

常用的是单向阀、安全阀、方向控制阀、速度调节阀等

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

•   Ideal for power plants and similar applications.

Direct Acting General Service Solenoid Valves Brass or Stainless Steel Bodies 1/8" to 1/2" NPT

Nominal Ambient Temperature Ranges: Class F Coils AC:  

32˚F to 125˚F (0˚C to 52˚C) Class H Coils  AC:  32˚F to 140˚F (0˚C to 59˚C) Class H Coils  DC:  

32˚F to 77˚F (0˚C to 25˚C) (104˚F/40˚C occasionally) Refer to Engineering Section for details.，

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。

- 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.

当入口与出口达到启动压差时，通电后，电磁力先导小阀，

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；、
