초록

A special control valve plug is disclosed. It includes the integral combination (1) of a spherical radiused or ball type seating surface and (2) a conically tapered flow control tip. When the valve is closed, the spherical radiused plug seating surface provides a positive fluid seal. When the valve is open, the tapered tip provides precise proportionate and continuously variable control of fluid flow.
