Cage type Double Seated Control Valves Model VDC OVERVIEW

Cage type Double Seated Control Valves Model VDC OVERVIEW
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.
