Electric butterfly valve can be manually operated temporarily Source: Sansheng Trap Time: 2019-12-30 Clicks:
Electric butterfly valves belong to various electric valves and electric regulating valves. The connection methods of electric butterfly valves mainly include: flange type and disc type; the seal types of electric butterfly valves mainly include: rubber seals and metal seals. The electric butterfly valve controls the switching of the butterfly valve through a power signal. This product can be used as shut-off, control and check valves in piping systems. With manual control equipment, once a power failure occurs, you can temporarily manually operate it without affecting use.
(1) Adopting double eccentric structure, it has tighter sealing function when closed, and reliable sealing performance.
(2) The mating material of the sealing vise is stainless steel and nitrile rubber, which has a long service life.
(3) The rubber sealing ring can be located on the valve body or butterfly plate, and can be used for media with different characteristics for users to choose.
(4) The butterfly plate adopts a frame structure, which has high strength, large circulation area and small flow resistance.
(5) The overall baking paint can effectively prevent rust, and as long as the sealing valve seat sealing material is replaced, it can be used for different media.
(6) The valve has a two-way sealing function, which is not controlled by the flow direction of the medium, and is not affected by the space position during installation. Can be mounted in any orientation.
(7) Small size, light weight, reliable performance, simple matching, large flow rate, especially suitable for liquid and gas cleaner media.
Working power usually includes: AC220V, AC380V, etc. Input signal: 4 ~ 20mA 0 ~ 10v and other weak current signals. After the electric actuator and valve stem are adjusted, the hard-sealed butterfly valve valve plate is driven by electric energy as a driving force.
