Sanitary check valve SBO series

for HVACbrassspring

Gravity circulation checks SBO for sanitation and heating SBO gravity circulation checks are installed downstream of circulating pumps in heating and hot water systems, to prevent gravity circulation. They replace the isolating valve in the feed line and remain in the pipe if a pump is removed, so that the system no longer needs to be fully drained. There are three connections for different pump designs up to PN 6.
