It can be represented in general form as np/ns, where np is the number of ports connected to the direction control valve and ns the number of switching positions. There are two fundamental positions of directional control valve namely normal position where valve returns on removal of actuating force and other is working position which is position of a valve when actuating force is applied. A bi-stable pneumatic valve is typically a pilot valve that is a 3 ported 2 position detented valve. The motion switchtakes place when the cylinder reaches the end of its stroke, without any sensor needed to report that. Spool is of two types namely sliding and rotary. 0000004141 00000 n
