Hardware: Stainless Steel Bolts and Fasteners

Max Pressure: 150 PSI

Max Temperature: 180°F (80°C)

Connection: 4" Flanged, ANSI 150#

Operation: Under forward flow, the ball lifts to allow passage; when flow stops or reverses, the ball returns to the seat to minimize reverse flow. The phenolic “sinking ball” is designed to provide reliable seating in sewage and suspended-solids service.

Construction: The epoxy-coated ductile iron body provides strength and corrosion protection. A resilient seat supports positive shutoff, and the phenolic sinking ball offers corrosion resistance. Serviceability is supported by the access design: Two-bolt access cover for in-line service. A special floating ball option is available for flood control or air vent applications—consult the factory for application and pricing.

Applications: Sewage lift stations, wastewater pumping, stormwater systems, sump and solids-handling service, and industrial piping where dependable backflow protection is required.

Flomatic Quality: Flomatic is known for engineered valves built for reliability and long service life. Each valve is designed with performance-focused materials and proven designs used in water and wastewater system applications worldwide.

Special Note: Special 4" model: connection is ANSI 150# flanged.
