German SED valves SED models SED prices
SED valves are used to prevent backflow of media, opening automatically using the fluid's own kinetic energy 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 against the valve seat to close. For wafer check valves, fluid flows from left to right

SED valves can automatically open and close based on the system's operating pressure. They are generally installed on equipment or pipelines in closed systems to protect system safety. When the pressure inside the equipment or pipeline exceeds the set pressure of the relief valve, it automatically opens to relieve pressure, ensuring that the medium pressure in the equipment and pipeline remains below the set pressure, thereby protecting the equipment and pipeline and preventing accidents. The working principle of SED valves is a type of hydraulic control valve. The main valve is divided into upper and lower parts by a diaphragm. The lower chamber of the diaphragm is the water flow channel, and the upper chamber is the control room, which controls the opening and closing of the main valve disc. The pilot valve itself is a relief valve.
