Series B

NPS 3 through 12 have been changed to reduce parts

and to improve control performance. The V-notch Ball

now resembles the NPS 14 through 20 V-notch Ball.

The pressed-in bushings have been eliminated, as well

as the thrust washer.

Micro-Notch Construction

For very precise control of low flow rates, the

Micro-Notch construction (see figure 3) is available on

NPS 1 valves. Three Micro-Notch ball materials are

available: chrome-plated CG8M (317 stainless steel),

solid alloy 6, and solid VTC ceramic. A VTC ceramic HD

seal is standard with the VTC ceramic ball. For the

CG8M and alloy 6 constructions, pressure and

temperature capabilities are the same as for standard

constructions. For the ceramic construction,

maximum temperature is 93_C (200_F).
