German HEKON valves HEKON models HEKON prices

HEKON valves, also known as globe valves, are forced-seal valves. Therefore, when the valve is closed, pressure must be applied to the disc to force the sealing surfaces to prevent leakage. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing, plus the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the diameter of the valve stem must be large; otherwise, the valve stem may bend. According to the connection method, they are divided into three types: flange connection, threaded connection, and welded connection. Since the advent of self-sealing valves, the medium flow direction of globe valves
