Marshall Excelsior Accessories
MEC MEV & MEH
Designed for installation in stationary ASME applications such as bulk plant, skid tanks, underground and above ground containers as the primary pressure relief valve.
Designed for accurate pressure regulation for higher inlet and/or outlet pressure applications. Monitor version also available.
Marshall Excelsior 1133
Designed for applications where accuracy and fast response are critical. It is ideal for commercial/industrial equipment requiring high flow capacities.
Marshall Excelsior 1122H
These first stage regulators are used to reduce tank pressures for a second stage regulator to be used downstream (normally 10 PSIG) .
Marshall Excelsior 1622 & 1622E
These second stage regulators are used to reduce outlet pressures from first stage regulators (normally 10 PSI) to either 11”WC or 2 PSI.
Marshall Excelsior 1632
These twin-stage regulators combine first and second stage into one convenient design. Used for short pipe distances for outlet prssures of either 11″wc or 2 PSI.
Desinged to prevent gas outages by switching fom primary to secondairy cylinder when the primary cylinder is depleted. Primairy cylinder can be refilled while still in service
These models are used for smaller pipe sizes and lower flows. Installations include portable, RV & home appliances.
