Pneumatic Directional Control Valve Series
I. Characteristics
The pneumatically actuated shut-off valve is suitable for applications involving flammable, explosive, or power-free environments. In fully pneumatic control systems, it further demonstrates its unique advantages.
The K23JK series two-position three-way pneumatic control shut-off valve is available in two structural types: "normally open" and "normally closed." When a pneumatic signal is received, the valve spool shifts; once the pneumatic signal is removed, the spool automatically returns to its original position, restoring the valve to its initial operating state. This valve series features few sliding mating surfaces, has low requirements for air purification, and exhibits strong resistance to dust. For ports with diameters of 25 mm or less, a plate-type connection is used; for ports larger than 32 mm, a flange-type connection is employed.
