PRODUCT OVERVIEW
Electric stainless steel lug butterfly valve is composed of PSQ, HQ, UNIC, 361rs and other series angular stroke electric actuators (small, Q-type, explosion-proof) and lug butterfly valve. The valve body is imported from foreign technology and adopts the center line straight plate design and three-dimensional eccentric design. The valve seat and butterfly plate are almost free of wear. It has the sealing function of getting tighter and tighter, and meets the national GB / T13927-92 valve pressure test standard. It is not only used in the industrial process automation of electric power, environmental protection, chemical industry, steel plant, petroleum and other industries It is also applied to the cooling water system of thermal power station.
PRODUCT FEATURES
1. Small and smooth shell, small volume, light weight, simple wiring, beautiful and easy to move and maintain.
2. Superior performance, stable and complete, including ordinary type, potentiometer type, passive type, intelligent type, fast closing, slow closing, indicator display, etc.
3. The power loss rate is low, which can save a lot of cost.
4. The technology is advanced, the electronic part adopts imported components, the performance is stable, the mechanical part is processed finely, precision and wear-resistant, and is equipped with multiple protection devices to avoid damage caused by improper operation or overload. The manual electric device can be controlled manually at any time, and the compact structure optimization design eliminates the shortage of high working noise.
5. The intelligent integrated device has 4 ~ 20mA signal input and output, proportional regulation control and positioning, no manual control, position self-locking, simple connection, stable and reliable performance, high control precision, fast response speed, etc.
6. It is convenient to install on the valve. It can be directly installed on the manual valve without machining.
7. The voltage can be provided by AC220V, dc220v, DC24, AC110V and other power supplies.
