China Manufacturers Part Turn Valve Electric Motor Actuator Electric Valve Actuator for Chemicals

Product Description

 
Electric ball valve is a kind of part rotating valve, compare with the same sized of gate valve and globe valve, it can full-close and full-open when rotate to 90 degree. The ball valve has the advantage of small volume, light weight, strong function, high reliable and easy to installed in the pipeline. Valve channel's diameter equal with connection pipes', so the medium can flow pass without any leakage. The valve usually used in the occasion where has strict requirement. It not only can control the medium like air, liquid and steam, but also suit for controlling the sewage or the medium which contain the fibroid impurity.

    
Performance Feature
1. Apply to the occasion where need two-position cut-off and regulating.
2. Electric ball valve can achieve the medium cut-off and circulation functions inside the transmission pipeline of the petroleum industry, chemical industry, paper making, metallurgy, sewage treatment and oil tank truck these fields.
3. High sealing performance and flow capacity, easy to assemble and maintain, small flow resistance, reliable seal.
4. Electric valve has the advantage of small volume, light weight, large thrust, strong function, easy to operating, high reliability with the installed servo amplifier.
5. Can flow to any position, has a widely adjustable range, and it can used for high pressure and big diameter occasion to control the high viscosity medium with fiber and fine particle.
6. Directly mounted type, with servo amplifier installed inside. Controlling and operating by output and input 4-20mA signal and 3800VAC voltage. It has the advantage of easy to link, compact structure, stable and reliable operation.
