Marshall Excelsior Excela-Flo Full Size Back Mount Second State Regulator

These second stage regulators are used to reduce outlet pressures from first stage regulators (normally 10 PSI) to 11” WC in domestic installations. All MEC second stage regulators are green indicating low outlet pressure. Second stage regulator vents have 3/4” FNPT tapped ports and our exclusive E-Z grip screens located over the inlet. All MEC second stage domestic regulators feature a stainless steel inlet filter screen to reduce debris from passing through the regulator. Both the MEGR-1622 and the MEGR-1652 Series 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-Flo domestic regulators feature a 25 year recommended replacement life and our exclusive tear away leak check the adhesive sticker. Full-size second stage regulators have a large fabric reinforced diaphragm for superior downstream regulation, heavy-duty wrench flats, and a large 3/4” FNPT tapped drip lip vent to help prevent relief valve blockage. The MEGR-1622 Series have both the inlet and outlet in line where the MEGR-1652 series has a rear discharge back mount outlet for convenient wall mount applications.
