          一級傳動裝置

          Single-stage drive device

          產品簡介

          本產品采用蝸輪蝸桿傳動副。體積小、重量輕,輸出扭矩大、結構合理、操作方便,具有可靠的自鎖性。適用于90°回轉的蝶閥、球閥、旋塞閥等閥i門的控制。

          In this product a gear-worm drive set is used this product is characterized by small size, light weight, large output torque, rational structuSre, to open and having reliably self-hold capacity. It is suitable to control the 90° rotay buttefly valve, ball valve, cock valve and reulating valve, etc.
