External Pilot Type Specifications

External pilot type (SYJ300R) structure drawing

External pilot type (SYJ300R) structure drawing

Type that is separated from the main valve pressure and separately receives pressure from an external pilot valve.
Can be used in a vacuum (up to -100 kPa) and on low-pressure lines of 0.15 MPa or less.

Applicable ModelsBase Mounting Type (SYJ314R, SYJ324R)
Operating Pressure Range MPaMain pressure-100 kPa to 0.7
External pilot pressure0.15 to 0.7
  • *Please refer to the SMC catalog regarding manifolds.
  • *For body ported types, the external pilot type (SYJ3□2R) is a dedicated model for manifolds.
