  • Inverted bucket steam traps
    The inverted bucket is the most reliable steam trap operating principle known. The heart of its simple design is a unique leverage system that multiplies the force provided by the bucket to open the valve against pressure. inverted bucket steam traps open and close based on the difference in density between condensate and steam-the inverted bucket principle. They open and close gently, minimizing wear. This simple fact means that inverted buckets are subject to less wear than some other types of traps.Inverted Bucket Steam Traps belong to the family of mechanical traps. They operate on the difference in density between steam and water.

  • DIN swing check valve
    DIN swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position. Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
