[wafer type soft seal electric butterfly valve] product overview
It is widely used in water plant, power plant, steel plant, papermaking, chemical industry, diet and other systems for water supply and drainage, as regulation and cut-off use.
[wafer type soft seal electric butterfly valve] product features
1. Valve body features
(1) The valve adopts double eccentric structure, which has the sealing function of closer and tighter, and the sealing performance is reliable.
(2) The sealing material is stainless steel and NBR oil resistant rubber, with long service life.
(3) The rubber seal ring can be located on the valve body or the butterfly plate. It can be applied to different media for users to choose.
(4) The butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.
(5) The whole baking paint can effectively prevent corrosion and can be used in different media as long as the sealing material of sealing valve seat is replaced.
(6) The valve has a two-way sealing function, which is not controlled by the flow direction of the medium during installation and is not affected by the space position. It can be installed in any direction.
(7) The valve has unique structure, flexible operation, labor saving and convenience.
2. Characteristics of actuator
(1) Powerful functions: intelligent, adjustable, switch type.
(2) Small size: the volume is only about 35% of the same kind of products.
(3) Easy to use: single-phase power supply, simple wiring; unique ball shaped protruding structure, making observation more convenient; no refueling, no spot inspection, waterproof and rust proof, any angle installation.
(4) The protection device has double limit, overheat protection and overload protection. Full travel time 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual function.
(5) Intelligent numerical control: the built-in module adopts the advanced single chip computer and intelligent control software to directly receive the standard signal (4-20mA DC / 1-5vdc) output by the computer or industrial instrument, so as to realize the intelligent control and precise positioning of the valve opening.
