Operation: The eccentric plug design allows the plug to lift away from the seat early in the stroke, minimizing seat wear and operating torque. The buried service gear with perpendicular operating nut provides controlled quarter-turn operation from grade where vertical access is limited.

Installation: Intended for underground installations requiring side-mounted operating access. Mechanical joint ends comply with AWWA C111 standards. Proper bedding, backfill, and alignment are required to ensure long service life.

Construction: Built on an epoxy-coated ductile-iron body with a resilient Buna-N plug, V-Type packing, and a self-lubricating Type 316 stainless-steel thrust bearing for reliable sealing and smooth operation in buried service.

Applications: Wastewater treatment plants, sewage mains, buried transmission lines, and other municipal or industrial services where perpendicular operating access is required.

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