Marshall Excelsior introduced its Sentinel series second-stage dielectric regulators, used to reduce outlet pressures from first-stage regulators to 11-in. WC in domestic installations.

The regulators have FNTP drip lip tapped ports and E-Z grip screens located over the inlet. They also feature a filter screen to reduce debris from passing through the regulator. Both the MEGR-1622D and the MEGR-1652D series regulators offer relief performance that exceeds UL test requirements, providing double failure overpressure protection when used with MEGR-1122H, MEGR-1222H and MEGR-1622H series first-stage regulators, the company says.

According to Marshall Excelsior, the regulators also have a dielectric inlet connection designed to isolate upstream metallic piping from electrical current prior to piping entering a building, in compliance with NFPA 58.
