Plug valve a fit for multiple applications
Model 54-4MJ Flo-E-Centric plug valve from Flomatic Corporation

The Model 54-4MJ Flo-E-Centric plug valve with Mechanical Joint (MJ) connections from Flomatic Corporation is a heavy-duty service valve with a wide industrial application range. While it is primarily designed for the potable water and wastewater markets, other applications include handling a variety of liquids, slurries and gases, including air and some chemicals.

“With its round port, globe body eccentric plug design, it is a natural for easily passing and controlling flow with solids or slurries in wastewater systems, or can be used for feedwater in potable applications,” says Mike Jones, municipal/industrial product manager for Flomatic. “It is available in both flanged and MJ end connections.”

The round-port eccentric plug valves are designed in compliance with ANSI/AWWA C517-09. They are available from 2 through 12 inches, with a spherical full-ported seat/plug design, and 14 through 24 inches with a rectangular full-ported seat/plug. The valve body and top-work are epoxy-coated inside and out. The Mechanical Joint valve-end connection meets the requirements of ANSI/AWWA C111/A21.11. All fasteners and washers are stainless steel, making them suitable for water or wastewater service.

“It’s a product we have been considering and researching for several years as an addition to our wastewater valve offering,” says Jones. “As well as functional design features, we especially looked at the automation capability that would allow us to incorporate our FCEL Electric Actuator platform.”

The Flo-E-Centric spherical plug-forming circular seat and plug face are offset from the shaft centerline to provide tight shut-off and wear resistance. The specially designed plug moves in and out of the seat with minimal contact, resulting in low operating torque.

“The Flo-E-Centric automated plug valve as a part-turn, 1/4-turn valve provides a great automation value package,” says Jones.

The Model 54-4MJ has a totally enclosed and sealed worm gear actuator with position indicator for above-ground service, and externally adjustable open and closed stops. The worm segment gear is ASTM A536 Grade 65-45-12 ductile iron with a precision bore and keyway for connection to the valve shaft. Bronze radial bearings are provided for the segment gear and worm shaft. Alloy steel roller thrust bearings are provided for the hardened worm. All gear actuators are designed to withstand, without damage, a rim pull of 200 pounds on the hand wheel and an input torque of 300 ft-lbs for nuts. Jones says the response from the industry has been positive so far.

“We’ve had a very good response,” he says. “It is a product line we are very excited about because of the benefits it offers to the water and wastewater industry.” 800/833-2040;
