O         ■ Four way tandem center valve designed to operate double acting
             cylinders and bi-directional motors, etc.
          ■ One piece cartridge housing ensures internal concentricity.
I         ■ Coil: Waterproof, hermetically sealed, requires no O’Rings;
             Symmetrical coil can be reversed without affecting performance.                                                                                        PUSH
D         OPERATION
          De-energized, the spool lands block flow from the annular holes at port
          1 and port 3. Flow is allowed thru the center of the spool from port 2 to
          port 4.The spring and washers maintain this position. Top coil
          energized, the armature is pulled towards the top plug pulling the spool
          against the spring. Flow is allowed from port 2 to port 3 between the                                                                                1 B
