Series 581 ISO 5599/1 Valves

Quick Ship Series 581 Valves

Series 581 directional control valves meet ISO 5599/1 and are interchangeable with many other manufacturers. The 581, in ISO sizes 1, 2 and 3 offers higher flow rates as compared other ISO valves within the same size. Unique spool and sleeve assembly is isolated from vibration and outside forces for long life. Construction allows field convertibility for internal or external pilot control. Valves come with CNOMO operators, coils to be ordered separately. Subbases also ordered separately.

Product features:

  • Long service life of over 100 million cycles
  • Simple to repair - unitized spool / sleeve and gasket in body repair kit
  • Designed for non-lubricated service, Teflon® glide rings “loaded” by Buna-N O-Rings
  • Locking / Non-locking manual overrides
  • Flow control kit available for field installation
  • Valves come without coils for maximum flexibility to meet a variety of applications
  • Accessories: coils, NPT and ISO-G ported single subbases and manifolds, sandwich pressure regulators, electrical connector
