Series 12443, 15443, 22461 Gate, Globe & Check Valves

Brand: Vogt

Flowserve Vogt Valves V-Port valve is particularly suited for “Continuous Blowdown” applications in power plants and “Speed Control” applications in hydraulic systems.

The design of the valve ensures positive flow regulation without sacrificing the shutoff capability expected of a globe valve.

The V-Port flow control valves have specially designed discs for combination shutoff and throttling service.

The shutoff and throttling surfaces are completely removed from each other in such a manner to insure that consistent flow rates are achieved during operation and that the shutoff seating surface is not subjected to the high velocities that occur at the throttling surface.

The discs are designed with an extended cylinder, which has V-shaped slots. As the disc is raised, the flow area at the V-shaped slots is increased, achieving regulation.

The extended V-Port disc legs are fully guided in the valve body during full lift, ensuring minimum vibration of the disc. Flow area generation at the disc throttling and seating surfaces are controlled to insure that a linear flow characteristic is achieved.

Flow is directly proportional to the valve lift for a constant pressure drop. A stainless steel dial and indicator permit the operator to accurately regulate and duplicate the flow to a desired volume.
