Check
Valve 
此元件可執行「或」之功能,也就是說,假如有至少一個的信號出現,則即會有一輸出信號產生。 
This device has “OR” logic function, ie, when at
least 1 signal is detected, an output signal will be generated. 
或閥用於從不同的位置來控制閥或氣壓缸時之用,亦用於「或」邏輯迴路上。 
或閥有2輸入口(X,Y)及一輸出口(A)。它會自動封住沒有受壓之一端,如果兩個入口同時有信號,則較高之信號將接通至輸出口A上。 
This “OR” valve can be applied to control Pneumatic
Valve or Control Valve at different positions, also can be applied
to the “OR” logic circuit. There are 2 Input Ports (X,Y) and 1
Output Port (A). It will automatically close the input port which
is no pressure loading, if 2 input ports detect pressure signals
simultaneously, it will take the stronger signal and open the
output port for it.
