AVAILABLE IN FOUR ISO 5599-1 SIZES, 581 OFFERS THE ENTIRE PERFORMANCE RANGE OF PNEUMATIC VALVES, EITHER AS A SINGLE VALVE OR VALVE TERMINAL SYSTEM, WITH ELECTRIC OR PNEUMATIC CONTROL. THE 581 INCORPORATES A NON-LUBRICATED, BALANCED SPOOL AND SLEEVE CONSISTING OF A STAINLESS STEEL SLEEVE WITH A POLISHED INNER DIAMETER, A NYLON SPOOL, AND A SERIES OF STATIC O-RINGS ENCAPSULATED BY TEFLON WEAR RINGS TO REDUCE FRICTION.

PILOT PRESSURE FOR THE SOLENOID OPERATED VERSIONS CAN EITHER BE SUPPLIED INTERNALLY FROM THE #1 SUPPLY PRESSURE PORT OR EXTERNALLY FROM THE #14 PILOT PORT. ALL SERIES 581 SOLENOID VALVES ARE SHIPPED AS INTERNALLY PILOTED BUT, CAN VERY EASILY BE CONVERTED TO EXTERNALLY PILOTED WHEN NECESSARY. TO CONVERT A VALVE TO EXTERALLY PILOTED, IT IS NECESSARY TO REMOVE THE COVER PLATE AND FLIP THE GASKET. THE TAB SHOULD BE UNDER THE APPROPRIATE SYMBOL. EXCEPT 581. *61, DIFFERENTIAL PILOT VERSION.
