With a maximum supply pressure of up to 400 psi (27.6 bar) and output ranges up to 125 psi (8.6 bar), these pressure regulators can achieve flow rates of well over 200 SCFM. Once set to a desired output pressure, these direct-acting diaphragm-operated regulators maintain the setting permanently. The rugged die-cast zinc and aluminum housings are pressure tested to assure safe operation, and are designed to withstand harsh and abusive environments. Can be panel or pipe mounted.
