Technical bulletin

The D-series valve is a rotary control valve, a trunnion mounted, reduced bore ball valve featuring the Stemball concept, combined with effective noise/cavitation attenuation. The Q-D 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 DN150...900 (6"...36").
