- 1 - 9th edition No. SS2-8110-1100 Cage type Double Seated Control Valves (Rating : ANSI 600 or Less) Model VDC OVERVIEW Model VDC control valve has a smaller actuator available for higher differential pressure as well as faster response in throttling action because of excellence in pressure balancing effect. The plug has less vibration-generating shape and all parts are housed in the cage, thus realizing anti-vibration and wearing-out resistant features. Valve body can be disassembled with ease. Inspection of trim and replacement of parts can be carried out rapidly. Capacity change by reducing port is performed by only replacing the cage with the plug unchanged.
