  • Engineered to provide bidirectional bubble-tight shutoff and isolation of the line media from the stem or valve body. 
  • Additionally, available with a unique stem seal arrangement to guarantee media containment.
  • Can be easily automated for on-off or modulating service with an ISO 5211 mounting pad.
