Precise pressure control and pressure adjustment can be critical factors when working with either pressure fed fluids, air pilot regulator supply or during test and inspection applications. R&D engineers from SMC, the world leaders in pneumatic technology, have long recognised this fact and have now developed a new, improved, range of direct operated precision regulators, Series ARP 20/30/40.Developed using SMC´s extensive knowledge of direct operated regulators, Series ARP now offers several advantages over previous SMC models including a decrease in air consumption by up to 80% compared to previous models – less than 1 ℓ/min (ANR) at 0,4 MPa - more precise pressure adjustment – repeatability is within ±1% and sensitivity is now within 0,2% of Full Scale.Further benefits of this new modular regulator range include digital pressure gauges fitted as standard and reverse flow functionality.
