SENTINEL™ Series Second Stage Dielectric Regulators are used to reduce outlet pressures from first stage regulators (normally 10 PSI) to 11” WC in domestic installations. All MEC SENTINEL™ Series second stage regulators are green with yellow inlet connections indicating low outlet pressure and dielectric separation. Second stage regulator vents have FNPT drip lip tapped ports and our exclusive E-Z grip screens located over the inlet. All MEC SENTINEL™ Series second stage domestic regulators feature an all stainless steel inlet filter screen to reduce debris from passing through the regulator. Both the MEGR-1622D and the MEGR-1652D Series regulators offer optimal relief performance that well exceeds UL test requirements providing double failure overpressure protection (no more than 2 PSI downstream pressure) when used with MEGR-1122H, MEGR-1222H and MEGR-1622H Series First Stage regulators. All MEC Excela-FloTM domestic regulators feature a 25 year recommended replacement life and our exclusive tear away leak check adhesive sticker.
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 complaince 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.
