EAV valve ordering code with10/20 and30C/E/P pilot functions

Helpful for Model Matching:

  • Full EAV valve code and circuit10/20/30C/30E/30P
  • Size200/300/400/600, installed ISO5599-1 interface and mounting drawing
  • Working pressure differs for single/double pilot; external pilot supply0.2–1.0MPa
  • Matching ESV base type,PT/G thread,pilot feed and side/bottom port configuration
  • Quantity,destination and base/valve assembly scope
  • Match EAV size,circuit and ISO5599-1 installed interface
  • Valve must use matching ESV sub-base;confirm full base configuration
  • Keep pilot and working pressure separate

Avoid a wrong match

  • Retain30C/E/P center;30 alone is incomplete. EAV is externally air-piloted, not a coil-voltage code.
  • Negative working pressure applies to double air control only; external pilot supply must remain0.2–1.0MPa. Confirm vacuum application through the inquiry.
  • Valve code does not encode threaded ports; ports and PT/G belong to the ESV base. NPT is not published.
  • ISO5599-1 does not establish cross-brand interchangeability by itself. Send the installed interface/drawing.
  • 200/300/400 manifold bases require end plates;600 manifold assembly additionally uses ESV604M side-port block. Do not assume base configurations are interchangeable.
  • Catalogue P125 allows mixing individual/centralized pilot feeds but P127 requires the same feed type. Confirm the assembly before mixing; no mixing capability is promised.

Read the model code

If the label is incomplete, send the readable parts together with a photo.

About EAV

EAV10 is single-pilot5/2; EAV20 is double-pilot5/2; EAV30C/E/P is double-pilot5/3 with closed/exhaust/pressure center. Size200/300/400/600 follows the published series code, not an inferred ISO size number. The valve must be used with a matching ESV individual or manifold sub-base; external pilot supply is separate from working air.

Matching Questions

Can EAV operate with vacuum or without electricity?

EAV uses external air pilot supply, not a valve coil. The catalogue permits negative working pressure for double air control only, while pilot pressure must be0.2–1.0MPa. Send the actual circuit and application for confirmation.

What should I send for a valve and base quotation?

Send the complete EAV code, installed ESV base code or photos, quantity and destination. Confirm individual/manifold sub-base, end plates,PT/G,pilot feed and port position;600-size assemblies have additional restrictions.
