美国ALKON先导阀ASK594系列：
Air pilot operated valves are recommended for applications where the substitution
of pilot air circuitry for solenoid operated valves is more suitable.
Controlled pilot signals using pilot air systems show comparable response to
electrically operated valves, and in many cases, response is enhanced by their use.
3-way valves may be used normally open, normally closed, or as a selector or
directional valve without modification. They are operated with an air pilot signal.
美国ALKON先导阀ASK594系列：
The ASK594 Valve wasfirstdevelopedin1963for theglass making machine industry.
It is basically a 4-Way, air pilot, spring return valve with a visual indicator. The base may
be mounteddirectlyontopof a cylinder withportingconformingtothe “SK”base
interface. Thebase, exhaust restrictors, andisolationvalve areoptional. The ASKis the
newest version of the same valve.
MODEL DESCRIPTION
ASK-594V Valveonbase,noindicator withexhaust restrictors
ASK-5645V Valveonbase, withindicator withexhaust restrictors
ASK-5946V Valveonbase, withindicator without exhaust restrictors
Note: Specify lessbase, ifbase isnotneeded.
3072-C Isolation Valve
This functionalunit easily adapts tothe ASK594valve toprovide aquick manual system
shutdown. Althoughthe ASK594normallyoperates as a4-Way airpilotedvalve,by
insertingthe3072-Cbetweenthe airpilot endcapandthe valvebody, the airpilot
signal isblockedtothe mainvalve andthe ASKspool returns toade-energizedposition.
SP-3207 Dual Isolation Valve
Just like the3072-C, this valve adapts easily tothe ASK594valve toprovide aquick
manual system shutdown while, at the same time, blocking the signal to another remote
valve in the system. This provides a simultaneous isolation of the dual pilots.
美国ALKON先导阀ASK594系列的共同特点
1）与固定液阻组成先导控制液桥，根据输入信号对主阀或次级阀或变量杠进行控制；
2）先导阀的流量一般都只在1升/分左右，大3升/分。二级先导阀流量就要根据实际需要决定。
3）输入信号都比较小；
4）可以接受多种输入方式，如手动、电动、液动、气动、机械凸轮、电比例等；
5）在变量泵控制等情况，多种先导阀形成模块化结构，多种功能取舍方便；
6）先导阀本身往往就是一种小规格控制阀，多为压力控制阀。
