V300-TGD Series Balanced Three Way Diverting Control Valve
Traditional three way control valves usually possess unbalanced trim types, the bigger the body size, the higher the unbalanced force, therefore the lower the allowable differential pressure.
When large diameter merging and diverting universal three way control valves are adopted in diverting conditions, the plug is easy to oscillate and unstable when it is close to the seat.
V300-TGD Series Balanced Three Way Diverting Control Valve, featuring balance seal ring structure, low unbalanced force, high allowable shut-off pressure, stable performance and high leakage level, is able to meet the requirements of large diameter and high differential pressure three way control valves in extra-large devices.
The standard actuator configuration is multi-spring diaphragm; other actuator types such as cylinder, electric and hydraulic are also available.
