If you operate high-volume fuel delivery trucks utilizing Liquid Controls M15 or M25 positive displacement meters, your efficiency boils down to one primary metric: flow rate. Every minute your equipment spends idling during a bulk transfer translates directly to lost revenue and increased wear on your pumps. Unfortunately, many fleet operators unwittingly choke their high-volume systems by pairing 3-inch meters with restrictive, legacy valve configurations.

This is exactly where the Liquid Controls E-15 Valve (A3982 Series) steps in, specifically engineered to solve the three biggest headaches found in 3-inch commercial petroleum plumbing systems.

Historically, adding electronic preset automation to a 3-inch line required using a standard 2-inch block valve squeezed between bulky 3″ x 2″ reduction adapters. This creates a severe fluid restriction, forcing your pumps to work significantly harder, spiking system pressure drop, and severely dragging down delivery speeds.

The Liquid Controls E-15 is a true 3-inch, two-stage electronic preset valve that bolts directly to the outlet of M15 (200 GPM) and M25 (300 GPM) meters. By maintaining a uniform 3-inch bore, it delivers maximum flow rates with minimal pressure drop.

When pumping refined fuels or lube oils at 200 to 300 GPM, slamming a valve instantly shut creates dangerous hydraulic shock. This violent pressure spike routinely warps internal meter components, damages seals, and destroys piping over time.

Paired with an electronic register like the Liquid Controls LCR.iQ, the E-15 utilizes a smooth, two-stage shutdown sequence. It effortlessly throttles down to a gentle “dwell flow” right before completing a preset batch, completely neutralizing shock.

On fuel delivery vehicles and modular loading skids, space is at an absolute premium. Eliminating physical reduction adapters means the E-15 offers a highly compact right-angle footprint, shedding unnecessary weight and letting you position the outlet exactly where you need it.

Stop letting restrictive valves hold back your M15 and M25 meters. Upgrade to a true 3-inch custody transfer solution and watch your delivery speeds soar.
