SMC AK14PAT Air-Operated General Gas Regulator (Medium Flow, Tied Diaphragm)

SMC AK14PAT Air-Operated General Gas Regulator (Medium Flow, Tied Diaphragm)

SMC AK14PAT series air-operated tied-diaphragm general gas regulator in stainless steel or brass for medium flow (below 400 slpm).

Key features

  • Air-operated (dome-loaded) set point: pilot air sets outlet pressure 0.05-1.0 MPa; pilot air isolated from process gas by a double seal
  • Stainless steel (SUS316) or brass body for general and specialty gases; Ni-Cr-Mo internals available for corrosive gases
  • Inlet up to 2300 psig (15.9 MPa), HR option 20.7 MPa; flow below 400 slpm
  • NPT1/4 to 1/2 female or 1/4 to 1/2 compression fitting connections
  • 2P, 3P bodies (stainless) and 4PL, 5PC bodies (stainless or brass)
  • Listed codes: gauge ports "0" (NPT1/4 port, no gauge); gauges (V3 to 40), plug C, MPA scale, VS/PK/TF seat and panel mount (P) are ordered as suffixes
