The Flomatic 54-0 FLO-E-CENTRIC® 20" plug valve (P/N 540000200) is a heavy-duty eccentric plug valve equipped with a gear box for controlled quarter-turn operation in wastewater and solids-handling service. The eccentric plug action helps reduce seat wear and operating torque while providing dependable shutoff in demanding applications.

Operation: FLO-E-CENTRIC® eccentric plug valves use an offset plug that rotates away from the seat early in the stroke, minimizing rubbing and helping maintain tight shutoff over time. The gear box provides smooth, controlled quarter-turn operation—especially beneficial on larger sizes where consistent torque and precise positioning are important. Operate the valve fully open or fully closed for best performance, unless the application specifically calls for throttling.

Installation: Suitable for horizontal or vertical installation. Verify flange compatibility, gasket selection, and bolt torque per site standards. For larger line sizes, provide proper pipe support and alignment to prevent external loads from transferring to the valve body. After installation, cycle the valve several times to confirm smooth operation and correct travel.

Construction: Built on an epoxy-coated ductile-iron body designed to withstand corrosion and abrasive service. The resilient Buna-N plug supports dependable sealing and helps resist wear from suspended solids. The gear box assembly is designed for durability and repeatable operation in wastewater environments.

Applications: Wastewater treatment systems, sewage lift stations, sludge handling, industrial process piping, and other services involving viscous or solids-laden fluids. Common uses include isolation service on influent/effluent lines, bypass lines, and process control points requiring reliable shutoff.

Flomatic Quality: Flomatic designs and manufactures valves engineered for reliability and long service life using proven designs and materials for water and wastewater systems. Each valve is built to deliver consistent performance in real-world municipal and industrial installations.

Important: Confirm suitability for the specific fluid, temperature, and pressure conditions of your application. Follow manufacturer installation and maintenance guidance for best results.
