SENTINEL™ Series Second Stage Dielectric Regulators feature an integral dielectric inlet connection designed to isolate upstream
metallic piping from electrical current prior to piping entering a building in compliance with NFPA 58 – 2020 section 6.11.3.17. Since
the FNPT inlet serves as the dielectric separation media, any standard MNPT threaded connector or valve can be installed without a
separate dielectric union. Both compact and full-size models feature the same basic footprint measurement from inlet to outlet, as
all standard Excela-Flo second stage regulators, making it ideal for regulator change-outs.

Compact second-stage regulator features adjustable range from 9.5-13" WC, stainless steel internal components and large aluminum precision machined orifices to provide superior downstream regulation. Also features new patent pending anti-freeze heat transfer fins, (2) 1/8" FNPT #54 orifice pressure taps and internal spring loaded relief.

Full size second-stage regulator features adjustable range from 9-13" WC, stainless steel internal components and large aluminum precision machined orifices to provide superior downstream regulation. Large 3/4" tapped drip lip vent to help prevent relief vent blockage, (2) 1/8" FNPT #54 orifice pressure taps and internal spring loaded relief.

Universal Bowtie Regulator Bracket

Application:
The MEC Flex-Vent provides a safe and easy solution to vent LP Gas regulators away from openings, sources of ignition or other potential fire hazards. Meets all requirements of the new flexible material allowance in the 2011 NFPA-58, section 5.8.3.1 (3).
