D241W-1The electro-hydraulic butterfly valve is a new type of product with strong applicability. The electro-hydraulic push rod is used as the power source, and the pressure oil is sent to the oil cylinder through the control of the oil circuit integration block to realize the reciprocating movement of the piston. At the same time, the valve shaft and valve plate are rotated in a range of 90 ° by the crank to achieve the purpose of regulating the flow. It is widely used in dry metallurgy, mining, electric power, building materials, medicine, chemical industry and other industries. It can control the flow of medium in the pipeline remotely or on site.

The valve has: sensitive action, stable operation, can effectively buffer the external impact force, accurate stroke control, can start with load and overload protection function, it is a mechanical, electrical, hydraulic integration of fully closed structure, the working oil circuit circulates in the non pressure closed steel cylinder, small volume, no oil leakage, easy installation and maintenance. It can work in harsh environment, no dust, no water, low energy consumption, long service life and so on.

Main performance nominal pressure: 0.1 MPa
Applicable temperature: ≤ 300%
Applicable medium: dust laden flue gas
Power supply voltage: three phase 380 V
