4 inch flanged electrically operated butterfly valve performance features
Electric butterfly valve belongs to a category of electric valve and electric regulating valve. The connection modes of electric butterfly valve are mainly flange type and clamp type; the sealing forms of electric butterfly valve are mainly rubber seal and metal seal. Electric butterfly valve controls the opening and closing of butterfly valve by power signal. This product can be used as cut-off valve, control valve and check valve of pipeline system.
Features introduction:
(1) It adopts double eccentric structure, which has the function of sealing that becomes tighter as it is closed, and the sealing performance is reliable.
(2) The sealing auxiliary material is a pair of stainless steel and nitrile oil-resistant rubber, which has a long service life.
(3) The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to media with different characteristics for users to choose.
(4) The butterfly plate adopts a frame structure with high strength, large flow area and low flow resistance.
(5) The whole valve is painted, which can effectively prevent rust and can be used for different media by replacing the sealing material of the valve seat.
(6) This valve has a two-way sealing function. During installation, it is not controlled by the flow direction of the medium and is not affected by the spatial position. Can be installed in any direction.
(7) It has small size, light weight, reliable performance, simple matching, large flow capacity, and is particularly suitable for media such as relatively clean liquids and gases.
