High Pressure Service Cage type Double Seated Control Valves Model VDC

High Pressure Service Cage type Double Seated Control Valves Model VDC
No. SS2-8110-1200
High Pressure Service Cage type
Double Seated Control Valves
(Rating: ANSI 900 to 2500)
Model VDC
OVERVIEW
Model VDC high pressure service control valve with
body rating of ANSI 900, JIS 63K or up provides
pressure balancing hole in the valve plug, thus,
effectively eliminate the unbalanced thrust force on
the plug, and relatively small actuator is selectable
for high pressure differential service.
The entire valve plug is housed wholly in the cage
and guided by guiding part, which makes it durable
construction both against vibration and wear.

The upper figures denote operating allowable differential pressure. The lower denote allowable differential pressure at full closure.
When inlet pressure is larger than differential pressure when a valve is fully closed, use the inlet pressure for actuator sizing.
