SMC AP20-D Modular Relief Valve (1/8, 1/4)

SMC AP20-D Modular Relief Valve (1/8, 1/4)

SMC AP20-D modular type relief valve that exhausts pressure above the set value to atmosphere, connecting directly to AC-D modular units with common IN ports.

Key features

  • Exhausts excess pressure to keep the set pressure; set range 0.05 to 0.8 MPa or 0.02 to 0.2 MPa (-1)
  • Common IN ports on both sides allow modular connection without branch piping
  • Gauge options: square embedded (E) or round gauge with limit indicator (G), round gauge with color zone (M)
  • Other options as symbols: bracket (B), panel nut (H), IN-port plug (N), built-in silencer (S), handle up (Y), psi units (Z)
  • Handle with finger grip; Rc thread standard, NPT (N) and G (F) available
