Electric stainless steel lug type butterfly valve-Electric valve series-电动阀厂家-上海冠环阀门制造有限公司

Product overview

Electric stainless steel lug butterfly valve is composed of PSQ, HQ, UNIC, 361RS and other series angular travel electric actuator (fine small, Q type, explosion-proof type) and lug butterfly valve two parts. The valve body introduces foreign technology, adopts the center line straight plate and three-dimensional eccentric design, the valve seat and the butterfly plate are almost no wear, with the tighter sealing function and in line with the national GB/T13927-92 valve pressure test standard. Not only used in power, environmental protection, chemical, steel, oil and other industries of industrial process automatic control system, but also used in thermal power plant cooling water system.

Product characteristic
1, the shell is small and smooth, small size, light weight, simple wiring, beautiful and easy to move and maintain.
2, the performance is superior and stable, there are ordinary type, with potentiometer type, passive type, intelligent, fast close slow close, indicator display and so on everything.
3, low power loss rate, can save a lot of costs.
4, advanced technology, electronic parts using imported components stable performance, mechanical parts processing fine precision wear-resistant, with multiple protection devices to avoid improper operation or overload caused damage, manual electric device can be manually controlled at any time, compact structure optimization design to eliminate the lack of noise.
5, the intelligent integrated device has signal 4 ~ 20mA input and output, proportional adjustment control and positioning, no manual control, position self-locking, simple connection, stable and reliable performance, high control accuracy, fast reaction speed, etc.
6, it is very convenient to install on the valve, but it can be directly installed on the manual valve without mechanical processing.
7, the voltage is AC220V, DC220V, DC24, AC110V and other power supplies can be provided.
