See pages ii & iii 8-26-04 12, 12A, 12B & 38 Series 3/8 & 1/2 NPT 3 1 5 2 4 12 14 3 1 5 2 4 12 14 4-Way - 5 Ported - 3 Position - Type F “Float” Center position - Inlet blocked and Cylinders open to exhaust. Used to vent both ends of cylinder to allow cylinder to float with a manual or machine movement. Flow controls or exhaust speed controls should not be used. 4-Way - 5 Ported - 3 Position - Type B “Blocked” Center position - All ports blocked and isolated. Use on conventional block and hold circuits. 3 1 5 2 4 12 14 3 1 2 12 10 2-Way or 3 Way - 2 Position - Type 3 This 3 Way Valve may be used for any 2 Way, 3 Way, Selector or Diverter service. When used with internally supplied Solenoid Operators, the Supply Pressure must be con- nected to Port #1. For this same reason when a normally open Solenoid Valve is ordered the Solenoid Operator will be mounted on end 10 and the Spring on End 12. 4-Way - 5 Ported - 2 Position - Type 2 Use on all 4 Way - 2 Position applications Note : Any of these 4 Way Valves, except the internally supplied Solenoid Valves, (See Option -X) can be used as Dual Inlet, Single Exhaust. Using this concept, with different pressures for force application and retraction, can effect large savings of high pressure air and its cost. The larger the cylinder or the faster the cycle, the higher the savings.
