Globe valve operating principle

center line butterfly valve
operating principle and characteristics:Valve plays an cut off in its line in the medium and the important role of throttle, cut-off valve, as a kind of extremely important truncated class valves, which exert torque on the valve stem seal, valve stem in axial direction to the pressure on the disc, the valve sealing surface and the valve seat sealing surface fit closely, prevent leakage of medium along the gaps between the sealing surface.
The sealing pair of the globe valve is composed of the disc sealing surface and the seat sealing surface. The stem drives the disc to move vertically along the center line of the seat. The opening height of the globe valve is small in the opening and closing process, which is easy to adjust the flow, easy to manufacture and maintain, and the pressure is suitable for a wide range.
