Flomatic is proud to announce the expansion of their American Iron and Steel (AIS) complaint Model 4082 Ball Check Valve family with new sizes in 8 inches & 12 inches.

The Model 4082 Ball Check Valve is now available in a complete size range from 3 to 12 inches, according to the press release.

Additional AIS type valves and sizes for water and wastewater applications are available. Flomatic’s Model 4082 AIS Ball Check valve is a proven industry favorite and is virtually maintenance free. It is designed and built to meet AWWA C508 standards.

The valve is constructed of a strong ductile iron body coated internally and externally with a fusion bonded epoxy coating in compliance with ANSI/AWWA C550 standards. The epoxy coating provides superior abrasion and corrosion resistance. The valve features a clean-out cover permitting access to the inside of the valve without removing the valve from the pipe line.

The Model 4082 has ANSI class 150# flanged end connections, a NITRILE (Buna-N) covered metal sinking ball and stainless steel fasteners. The AIS compliant Model 4082 ball check valve also includes bosses to accommodate NPT tappings for additional optional components. The maximum pressure rating is 150 PSI and the maximum temperature rating is 180◦F (80◦ C).

Flomatic’s Ball Check valves have no moving parts except for the ball which automatically moves out of the flow path minimizing head loss and maximizing efficiency. The random seating of the ball also allows for a longer service life.
