SBC ball check valves reliably prevent the backflow of liquid process media in piping systems. Robust materials and durable linings ensure safe operation and a long service life, even under demanding process conditions.
SBC ball check valves ensure reliable backflow prevention in demanding process plants. They protect pumps, piping, and plant components from unwanted backflow, thereby contributing to safe and trouble-free plant operation.
Thanks to their high-quality PFA or PFA-AS lining, the valves are particularly suitable for corrosive process media. The solid PTFE ball ensures reliable shut-off, while the integrated borosilicate glass sight glasses allow for easy visual inspection. The ball check valves are available in DIN or ANSI versions and can be flexibly integrated into existing piping systems.
