The Flomatic 2142-3 408² 2" ball check valve is designed especially for use with sewage pumps and applications involving viscous liquids or slurries. The ball has sufficient weight to seat tightly in high-viscosity liquids while opening freely to help minimize headloss.

Specifications:

Body: Ductile iron with epoxy coating and access port

Connection: 2" Flanged, ASME Class 150

Ball: Nitrile (Buna-N) covered metal sinking ball

Hardware: Stainless Steel fasteners

Max Pressure: 150 PSI

Max Temperature: 180°F (80°C)

Recommended Flow Velocity: 3–5 ft/sec

Weight: 17 lbs

AIS: Not AIS compliant.

Operation: Flomatic ball check valves permit flow in one direction only and are tight seated when the outlet pressure exceeds the inlet pressure.

Installation: Ball check valves may be installed horizontally or vertically, with preferred installation in the vertical position. Install with the flow arrow in the direction of flow. If installed horizontally, the cover must be oriented to the top. Do not subject ball check valves to freezing conditions.

Construction: The epoxy-coated ductile iron body provides strength and corrosion protection. The Buna-N covered metal sinking ball and resilient seating components support dependable shutoff in sewage and solids-handling service. Stainless steel bolts and fasteners support long-term durability in wet environments.

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.
