SeriesCodeDescription
D1QD1NELES TRUNNION MOUNTED BALL VALVE SERIES D1, CLASS 600, WITH Q-TRIM VARIANT (Q-TRIM)

The D-series valve with Q-Trim is intended for applications where high Cv and excellent rangeability are required, combined with effective noise/cavitation attenuation. The Q-D1 valves are supplied as unidirectional one-seated version with specially designed ball control element to achieve improved noise/cavitation attenuation in gas, steam and liquid applications. The control seat is spring-loaded, capable of easing the contact on ball when throttling to eliminate friction, but assuring durable tightness at shut-off. Size range is DN 50...700 (2"...28") in class ANSI 600.
