Description
The CL31R features a relief-type pilot regulator to provide token relief and to prevent excess loading pressure from entering the main regulator should the pilot regulator fail. The CL31N features a non-relief pilot regulator and can be used for outlet pressures over the entire range without changing the pilot adjustment spring.
