Look beyond traditional globe control valves to a valve technology that gives you high pressure drop capability with straight-through flow, precision control, shearing action, erosion control and bubbletight shutoff.

The technology is a self-lubricated, full contact seat of sintered stainless steel impregnated with TFE or graphite. The flow characteristic is laser cut to a "V" shape, slots, or customized shapes to meet any control requirement. The controlling element is a super round, hard nickel coated ball with a round resilient or sintered stainless steel seat on the opposite side. The lubricating action of the special coating on the ball and TFE or graphite impregnation throughout the thickness of the characterized seat results in amazingly smooth, stable throttling control.

The characterized seat design allows use of exotic materials such as lnconel 6000, Hastelloy C220 or MonelO.
