Operation: FLO-E-CENTRIC® plug valves use an eccentric plug action to reduce rubbing at the seat and help maintain tight shutoff with low operating torque. The valve operates with a quarter‑turn open/close movement.

Installation: Suitable for horizontal or vertical installation. Confirm flange/thread compatibility and torque fasteners evenly. For buried or hard-to-reach installations, operate with an appropriate wrench on the 2" AWWA operating nut.

Construction: Built on a ductile-iron body with an epoxy coating for corrosion resistance. The Buna‑N plug and V‑type packing support reliable sealing, while the self‑lubricating Type 316 stainless-steel thrust bearing helps provide smooth operation.

Applications: Wastewater systems, sewage, sludge, industrial piping, and other services involving viscous or solids‑laden fluids.

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