螺旋止回閥 （SDNR）

This SDNR valve is use KMH series Hydraulic multi-turn actuator direct install on the gate

valves or global valves etc, by using worm and gear and thrust bearing, this type of actuator

can run smoothly, and high output torque ,low noise and high reliable, can reach IP68, Its

torque 150~7000Nm, valve size from DN100 to DN500 or above, the valve with cert of

major classification society according to requirement.

這款螺旋止回閥是使用KMH系列的液壓多回轉執行器直接安裝在閘閥或截止閥等閥門上，

由液壓馬達與齒輪蝸輪蝸桿箱組成動力，進行閥門開關的液壓多回轉執行機構，具有運

作平穩，扭矩大，噪音小，達到IP68防護等級，可以進行水下浸沒安裝，扭矩從150Nm到

7,000Nm, 閥門尺寸從DN100到DN500或更大尺寸,閥門根據要求帶有主要船級社證書.
