Electric butterfly valve introduction
Introduction
Electric butterfly valve belongs to a variety of electric valve and electric regulating valve. Electric butterfly valve connection methods mainly include: flange type and wafer type; electric butterfly valve sealing forms mainly include: rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as a shut-off valve, control valve and check valve for piping systems. With manual control device, once there is a power failure, it can be temporarily operated manually without affecting the use.
With the development of electric valves, many well-known valve companies at home and abroad produce electric valves. Electric butterfly valves are an important execution unit in the field of industrial automation control. It belongs to a variety of electric valves and electric regulating valves. It is widely used in textiles, power stations, petrochemicals, heating and refrigeration, pharmaceuticals, shipbuilding, metallurgy, light industry, environmental protection and other fields. The product can be used as a shut-off valve, control valve and check valve for piping systems. Complete manual control device, electric or pneumatic transmission device, can meet the specific conditions of different working conditions. It meets the most stringent quality requirements and can be used for a very long time. Especially in the metallurgical steel, shipbuilding industry, it has a very high reputation.
Features
(1) Adopting double eccentric structure, with tighter and tighter sealing function, and reliable sealing performance.
(2) The sealing material is made 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 different characteristics of media for users to choose.
(4) The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
(5) The overall baking varnish can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is replaced.
(6) This valve has a two-way sealing function, and it is not controlled by the flow direction of the medium during installation and is not affected by the spatial position. Can be installed in any direction.
(7) It has the advantages of small size, light weight, reliable performance, simple matching and large flow capacity, and is especially suitable for clean liquids and gases.
