SMC AR425 to AR935 Pilot Operated Regulator (Rc1/4 to Rc2)

SMC AR425 to AR935 internal pilot operated relief-type regulators for large flow, port sizes Rc1/4 to Rc2, in standard (0.05-0.83 MPa) and low-pressure (0.02-0.2 MPa) versions.

Key features

Internal pilot construction with relief, pilot air constantly bled (5 L/min ANR max.)
Four body sizes: AR4_5 (1/4, 3/8, 1/2), AR6_5 (3/4, 1), AR8_5 (1-1/4, 1-1/2), AR9_5 (2)
Standard AR_25 0.05-0.83 MPa and low-pressure AR_35 0.02-0.2 MPa setting ranges
Options: bracket (B, AR4_5/AR6_5), pressure gauge (G) or remote indicator gauge (P); flow direction right-to-left (R)
Thread Rc standard; NPT (N) and G (F) available
