傳統的三通調節閥通常為流體壓力不平衡型,口徑越大,不平衡力越大,其允許壓差就越小。當大口徑合流、分流通用型三通閥用于分流場合時,閥芯接近直通或旁通閥座時,極易產生振蕩,穩定性差。V300-TGD系列平衡型三通分流調節閥采用流體壓力平衡密封環結構,不平衡力小,允許關閉壓差大,穩定性好,泄漏等級高,可以滿足特大型裝置對大口徑高壓差三通調節閥的需求。執行機構標準配置為多彈簧薄膜式,氣缸式、電動、液動可供選用。
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.
