ZXMII/ZDLMII Pre-inlet cage control valve
ZXMII/ZDLMII 預(yù)啟式套筒控制閥采用先導(dǎo)結(jié)構(gòu)，流道呈S流線型。具有結(jié)構(gòu)緊湊、動作靈敏、閥容量大、流量特性精準(zhǔn)、維護(hù)方便等優(yōu)點，可用于較苛刻的工作條件。特別適用于大口徑高溫高壓的調(diào)節(jié)和切斷場合。
ZXMII/ZDLMII Pre-inlet cage control valve adopts pilot structure and its flow channel is stream line form-S.It has advantages of compact structure,quick action,huge valve capacity,precise flow characteristics,and easy maintenance,etc..It can be used in harsh working conditons,especially suitable for large diameter,high temperature and pressure adjustment and cut-off occasions.
