• Main dimensions and weight

The opening and closing component of the electric rubber lined diaphragm valve is a diaphragm made of soft material, which separates the inner cavity from the valve cover inner cavity and driving components. Diaphragm made of soft sealing materials such as rubber or plastic has good sealing performance. Due to the vulnerability of the diaphragm, it should be replaced regularly based on the characteristics of the medium. Electric rubber lined diaphragm valve is used for media containing hard suspended solids; Due to the fact that the medium of the electric lined diaphragm valve only comes into contact with the valve body and diaphragm, there is no need for a stuffing box, and there is no problem of stuffing box leakage, which may cause corrosion to the valve stem.
