Intelligent explosion-proof electric ball valve-Electric valve series-电动阀厂家-上海冠环阀门制造有限公司

Product overview

The intelligent explosion-proof electric ball valve is composed of an angular stroke explosion-proof electric actuator and a ball valve sphere, which is composed of an electronic angular stroke electric actuator 3810 or HQ series and a ball valve regulating mechanism. The valve has the characteristics of simple structure, rapid switching, large flow capacity, zero leakage, etc., suitable for high viscosity, containing fiber, solid particle fluid occasions, explosion-proof electric ball valve is widely used in petrochemical, metallurgy, light industry and other industrial automatic control fields to cut off or flow the medium of gas, liquid transmission pipeline. The actuator adopts integrated design, the input 220V power supply can be adjusted directly, and the built-in servo module can be used to control the operation of the input control signal (4 ~ 20mA DC or 1 ~ 5VDC) and single-phase power supply. Usually used in the case of strict sealing requirements, in addition to the control of gas, liquid, steam media, but also suitable for controlling sewage and media containing fibrous impurities. Widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station, refrigeration and other fields of work.

Main feature
1, suitable for two cut off, adjust the occasion.
2, can achieve the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanker and other transportation pipeline medium cut off and circulation.
3, excellent sealing performance, large circulation capacity, easy loading and unloading maintenance, small flow resistance, reliable sealing, and even cut off.
4, small size, light weight, large thrust, strong function, servo amplifier built-in, easy to operate, high reliability.
5, the flow direction can be arbitrary, wide adjustable range, can be used for high pressure and large diameter occasions, control high viscosity, with fiber and fine particles of the medium.
6, direct connection mode, electric actuator built-in servo system, no need to match servo amplifier, input and output signal 4-20mA and 3800VAC power supply can control operation. With simple connection, compact structure, moving
