CL231 R, N Gas Regulator

The CL231 Series is a compact, cost-effective regulator designed for mid-sized commercial applications (to 7500 SCFH) which require accurate regulation at elevated pressures. The CL231R features a relief-type pilot regulator to provide token relief and to prevent excess loading pressure from entering the main regulator when the pilot regulator fail. The CL231N features a non-relief pilot regulator and can be used for outlet pressures over the entire range without changing the pilot adjustment spring.
