Flomatic 540000070A 54-A FLO-E-CENTRIC® 4" Plug Valve

The Flomatic 540000070A 54-A FLO-E-CENTRIC® 4" plug valve is a quarter-turn, eccentric, resilient seated plug valve supplied with a 120VAC electric actuator for open/close service and a manual handwheel override. Designed in compliance with ANSI/AWWA C517, the eccentric plug lifts away from the seat during rotation to reduce friction and wear while maintaining dependable shutoff in wastewater and solids-handling applications.

Specifications:

Model: 54-A

Part No.: 540000070A

Valve design: Round-port, eccentric, quarter-turn plug valve (Series 5400)

Body: Ductile iron (ASTM A536 65-45-12), fusion bonded epoxy coated (NSF/ANSI 61 coating)

Seat: Welded nickel seat for corrosion and abrasion resistance

Plug: Spherical Buna-N (NBR) coated ductile iron plug

Electric Actuator Voltage: 120VAC

Hardware: Stainless-steel

Ends: Class 150 flanged

Porting: 100% full ported (2"–8"); 10"–12" are minimum 90% ported

Flow: Bi-directional flow capable

Max Pressure: 200 PSI

Max Temperature: 180°F (80°C)

Weight: 120 lbs

Operation: The eccentric plug offsets from the shaft centerline, allowing the plug to rotate and lift off the seat early in the stroke. This reduces seat rubbing, helps lower operating torque, and supports long service life in abrasive or solids-laden service. The included 120VAC actuator provides powered open/close control, and the manual handwheel override allows operation during maintenance or loss of power.

Installation: Installation must be performed by qualified, licensed personnel. Confirm flange/thread compatibility, gasket selection, and even bolt torque. Provide adequate line support so external loads are not transferred into the valve body. After installation, cycle the valve to confirm full travel and smooth operation. For actuator applications, consult the manufacturer guidance for mounting, wiring, and service conditions.

Construction: Built on a fusion bonded epoxy coated ductile-iron body with a welded nickel seat for corrosion and abrasion resistance. The Buna-N coated spherical plug and V-Type packing support reliable sealing, while the self-lubricating Type 316 stainless-steel thrust bearing with PTFE washers promotes smooth, repeatable operation. Stainless-steel hardware is used throughout for durability.

Applications: Wastewater and sewage lines, sewage sludge and slurry lines, wastewater treatment plants, mining and irrigation service, and industrial processes where slurries, solids, fibers, or grit may be present.

Options: Smart card option is available for modulating service (4–20 mA input/output and configurable control signals). For modulating service, consult factory for configuration and part-number requirements.

Flomatic Quality: Flomatic designs and manufactures valves engineered for reliability and long service life using proven designs and materials for water and wastewater systems.
