Pilot-Air-Controlled Compressed Air Regulators



Control hard-to-reach regulators without needing direct access. Instead of a knob, these regulators use a pilot signal from a regulator installed in an accessible location—often a control system—to adjust pressure remotely. As the input signal increases, the output pressure increases within the regulating range. Install them in your air line after filters.
Regulators with 1:2, 1:3, and 1:6 air signal-to-outlet ratios boost the air pressure from your main line. For example, a 1:3 regulator takes 20 psi from your programmable logic controller (PLC) or transducer and boosts it to the 60 psi your actuator needs.
