ME990SAR-6DFM-2400 (Marshall Excelsior) Excelerator 6 In. – 300Lb Modified Double Flange Internal Valve w/ Rotary Actuator – 2400 GPM

The ME990SAR-6DFM-2400 Excelerator internal valve from Marshall Excelsior is a high-capacity, 6-inch internal valve engineered for demanding LP-Gas and anhydrous ammonia applications. Designed for transport trucks, bobtails, and bulk storage systems, this valve provides reliable shutoff performance and enhanced flow capability in high-volume transfer operations.

Featuring a modified double flange (DFM) design, this valve incorporates a modernized flange configuration that improves durability, corrosion resistance, and compatibility with current tank standards. This is a factory-defined design—not a custom modification.

Equipped with a rotary actuator, the valve allows for smooth and dependable remote operation, making it ideal for systems requiring mechanical or cable-actuated control.

With an excess flow closing rating of 2400 GPM, this valve is built to handle high-flow applications while maintaining critical safety protection in the event of a line rupture.
