• Spool Assembly Note: Assemble type OA, 2A, and 6A spool in body with longer end land opposite of operator. Assemble type 1 spool in body with narrow center land towards A port. Assemble type 11 spool in body with narrow center land towards B port. Assemble type 3 spool in body with narrow center land towards A port. Assemble type 31 spool in body with narrow center land towards B port. Assemble type 7A and 22A spool in body with reduced longer end Dia. towards operator.
• V Option: Operator A is at port A end of valve and/or operator B is at port B end of valve, independent of spool type. Type 8 spool valves will always have a V present in model code.
• Service Life: For satisfactory service life of these components in industrial applications, use full flow filtration to provide fluid which meets ISO cleanliness code 18/15 or cleaner. OFP, OFR, and OFRS series filters are recommended.

Product Usage Instructions

1. Assemble the appropriate spool type (OA, 2A, 6A, 1, 11, 3, 31, 7A, or 22A) in the body of the valve according to the provided Spool Assembly Note.
2. If using the V Option, ensure that operator A is at port A end of the valve and/or operator B is at port B end of the valve.
3. Connect the valve to the appropriate circuits and interfaces.
4. Ensure that the rated pressure of 350 bar (5000 psi) is not exceeded.
5. If manual override option is required, select the appropriate spool with type 8 and assemble it accordingly.
6. For optimal performance and longevity, use full flow filtration to provide fluid that meets ISO cleanliness code 18/15 or cleaner. OFP, OFR, and OFRS series filters are recommended.
