梭阀是属于直行程阀门，是阀体与执行器合二为一体的阀。其优点体积小、安装方便所有的梭阀工作原理大致是差不多的。 梭阀 举例：意大利OMALVIP梭阀 关阀：当“A”孔进气（“B”孔排气）时，活塞向“D”口移动并压在阀座密封上，此时阀门关闭单动常闭型的弹簧安装在“A”端腔室。在非控制时，活塞是压在阀座上，所以其最常用的是关闭位。 开关过程：压缩空气由两孔中有一个孔进入推动活塞轴移动，改变了阀门原先的开或关的状态，常闭型，关靠弹簧力，常开型，开靠弹簧力，开或关的时间都少于一秒。 开阀：当“B”孔进气（“A”孔排气），活塞轴从阀座向“C”口方向移动并在行程末端停止，此时阀门开启。单动常开型的弹簧安装在“B”腔室，在非控制时，活塞轴是离开阀座的，所以其最常用的是开启位。 典型应用：气体工艺，制氧、制氮机，真空应用，卫生器皿业，制冷。 梭阀有两个进口IN，一个出口OUT。当进口中一个输入时，出口便有输出。若两个进口压力不等，则高压进口与出口相通。若两个进口压力相当，则先输入压力的进口与输出口相通。 梭阀相当于两个单向阀组合的阀，其作用相当于“或门”。梭阀有两个进气口P1和P2，一个出口A，其中P1和P2都可与A口相通、但P1和P2不相通。P1和P2中的任一个有信号输入，A都有输出。若P1和P2都有信号输入，则先加入侧或信号压力高侧的气信号通过A输出，另一侧则被堵死，仅当P1和P2都无信号输入时，A才无信号输出。梭阀在气动系统中应用较广，它可将控制信号有次序地输入控制执行元件，常见的手动与自动控制的并联回路中就用到梭阀。

Straight trip shuttle valves are valves, valve and actuator is a combined body of the valve. The advantages of small size, easy to install all of the shuttle valve works roughly the same. Shuttle valve For example: Italy OMALVIP shuttle valve Off valve: When the "A" inlet hole ("B" vent hole), the piston to the "D" I moved and pressure seal on the seat, then turn off the valve normally closed type single-action springs installed in the " A "side chamber. In the non-controlled, piston down on the seat on, so the most common is the closed position. Switching process: the compressed air from the two holes in the promotion of a hole into the piston axis, change the valve on or off the original state, normally closed, off by spring force, normally open type, open by spring force, open or less than one second off the time. Open valve: When the "B" hole into the air ("A" hole exhaust), piston shaft from the valve seat to the "C" I move the end stop in the trip, this time the valve opens. Normally open type single-action springs installed in the "B" chamber, in non-controlled, piston-axis is the left seat, so the most commonly used is the open position. Typical applications: gas technology, oxygen, nitrogen, vacuum applications, health ware industry, refrigeration. Shuttle valve has two import IN, an outlet OUT. When an input imports and exports have output. If the two inlet pressure range, the import and export of high pressure connected. If the two inlet pressure equal to the input pressure of imports and output connected. Equivalent to two one-way valve shuttle valve combination valve, and its role is equivalent to "or the door." Shuttle valve has two inlet P1 and P2, an outlet A, which P1 and P2 can be connected with the A port, but the P1 and P2 are not connected. P1 and P2 for either a signal input, A has output. If P1 and P2 are the signal input, the first side or the signal to join the high side of the gas pressure signal output by A, the other side was blocked, only if P1 and P2 have no signal input, A was no signal output. Pneumatic shuttle valve in the wider application of the system, it can control the input control signal orderly implementation of components, common manual and automatic control of the parallel loop on the shuttle valve is used.
