Product Details

 butterfly type natural gas regulator valve

Product Specification                                                                 

The electric soft seal butterfly valve is characterized by simple structure, small volume, light weight. The butterfly valve is full open or closed when the disc is rotated a quarter turn with good flow control characteristic. It’s very small pressure from the disc when the butterfly valve is in full open position. They are widely used in water supply, fire protection, air condition, environmental protection, food, light industry, electrical, petroleum, papermaking and so on. 


Integrated structure electric wafer butterfly valve match with FOSD Electric actuator. and can be run with input (4-20mA DC, 0-10VDC or 1-5V) signal-phase power. With the function of small volume, flow capacity, high regulation precision, good sealing, and light weight.ect. The valve is widely used food, environmental protection, light industry, petroleum, paper, chemicals, teaching and research equipment, and electric power industries if inductrial automation control systems.
