DG18 V-3- A Series Air Pilot Operated Directional Control Valve

Product Information

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.
