SMC AP14PAT Air-Operated High-Purity Regulator (Medium Flow, Tied Diaphragm)

SMC AP14PAT Air-Operated High-Purity Regulator (Medium Flow, Tied Diaphragm)

SMC AP14PAT series air-operated high-purity tied-diaphragm regulator set by pilot air, for medium flow (below 400 slpm) process gas lines.

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
  • High-purity SUS316L double-melt body, electropolished and passivated; precision cleaned and helium leak tested
  • Inlet up to 2300 psig (15.9 MPa), HR option 20.7 MPa; flow below 400 slpm
  • Ni-Cr-Mo alloy internals as standard
  • 2, 3 or 4-port bodies with 1/4 to 1/2 face seal or tube weld connections
  • Listed codes: gauge ports "0" (1/4 face seal male port, no gauge); gauges (V3, L, 1, H, 2, 4, 40), MPA scale, VS/TF seat, HF high-flow and panel mount (P) are ordered as suffixes
