SISTO valves are used to prevent backflow of media, opening automatically using the kinetic energy of the fluid itself and closing automatically during reverse flow. They are commonly installed at pump outlets, steam trap outlets, and other locations where reverse fluid flow is not permitted. Check valves are classified into three types: swing check, lift check, and wafer check. For swing check valves, fluid can only flow from left to right, and they close automatically during reverse flow. For lift check valves, when fluid flows from left to right, the valve disc lifts to form a passage; during reverse flow, the disc is pressed tightly against the valve seat to close. For wafer check valves, fluid flows from
