Marshall Excelsior currently specifies the ME880-6/14 as a brass valve with 3/4" MNPT inlet, 3/4" FNPT outlet, and 14 GPM propane closing flow.

Complete Description

For sale is a genuine Marshall Excelsior ME880-6/14 Excess Flow Valve, designed for use in compatible liquid or vapor LP-Gas and NH3 systems.

This valve features a 3/4" MNPT male inlet and 3/4" FNPT female outlet, with a specified 14 GPM propane closing flow. The body is manufactured from brass, while Marshall Excelsior specifies stainless-steel internal components.

The excess-flow mechanism is designed to help limit excessive product discharge if a hose or piping system experiences a major break that causes flow to exceed the valve's closing-flow threshold. Once activated, the valve remains closed until system pressure equalizes across the shutoff poppet.

Key Features

  • Part number ME880-6/14

  • Suitable for container and in-line applications

Applications

The ME880-6/14 can be used in compatible LP-Gas or NH3 systems for filling, withdrawal and vapor equalization, including container installations, long piping runs and branch piping. Marshall Excelsior specifies the valve for direct installation into pressure vessels and/or piping.

Typical applications include propane bulk-storage systems, industrial LPG equipment, tank piping, transfer systems and other compatible liquid/vapor installations.

Important: An excess-flow valve is not a general leak detector. Marshall Excelsior warns that it will not activate if downstream leakage or a break does not produce flow equal to or greater than the valve's closing-flow rate, or if the selected valve exceeds the system's available flow capacity. 

Match the manufacturer part number and equipment model to the listing. Check connection sizes, fuel type, pressure or capacity, voltage and dimensions where applicable. A similar appearance or part number alone does not confirm compatibility.

For help, send a parts inquiry with the part number, equipment model, label photos and quantity. Manufacturer documents and item-specific information, when supplied, are in the product details above.
