Product description
Overview of electric wafer soft seal butterfly valve products
The butterfly plate of the electric wafer soft seal butterfly valve is installed in the diameter direction of the pipeline. It not only has excellent corrosion resistance, (alkali and salt resistance, weak acid corrosion resistance), wear resistance and wear reduction performance, but also has the characteristics of non-toxicity, antibacterial and mildew resistance, and has the outstanding advantages of small operating torque, (40% lower than ordinary pin butterfly valve), convenient maintenance and beautiful appearance. Generally, it should be installed horizontally in pipelines. It consists of rubber sealing butterfly valve, carbon steel or stainless steel valve plate and valve stem. Electric rubber-lined butterfly valve is suitable for regulating flow and intercepting medium in water supply and drainage and gas pipelines with temperature ≤ 80 ~ 120ºC, such as food, medicine, chemical industry, petroleum, electric power, textile and paper making.
Product characteristics of electric wafer soft seal butterfly valve
(1) rubber lining and no pin are adopted, which ensures the complete isolation of medium and metal and improves the reliability of products.
(2) The sealing surface has good wear resistance (the wear resistance of rubber is seven times that of copper).
(3) It can be installed at any position and is convenient for maintenance.
(4) The sealing element can be replaced, and the sealing performance is reliable to achieve zero leakage in bidirectional sealing.
(5) Rubber materials have no toxicity, and are antibacterial and mildew resistant.
Actuator parameters and characteristics
(1) Powerful functions: intelligent, adjustable and switching.
(2) Small size: the volume is only about 35% of that of similar products.
(3) Easy to use: single-phase power supply, simple wiring; The original spherical protruding structure is adopted to make observation more convenient; No oiling, no spot inspection, waterproof and antirust, and installation at any angle.
(4) The protection device has double limit, overheat protection and overload protection. The total travel time is 15 seconds, 30 seconds, 45 seconds and 60 seconds. And with manual function.
(5) Intelligent numerical control: The built-in module directly receives the standard signals (4-20mA DC /1-5VDC) output by computers or industrial instruments by using advanced computer single chip and intelligent control software to realize intelligent control and accurate positioning of valve opening. You can also choose 3810 series or NA series electronic angular travel actuators, and you can also choose PSQ series or HR series. Generally, valves with diameter ≥DN600 adopt 380VAC electric actuator.
