At present, there are many manufacturers of AWWA c504 butterfly valves domestically and abroad. ZECO Valve Company plays an important role in the development, production and manufacture of such valves.
The disc of the AWWA C504 butterfly valve is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0掳 and 90掳. When the rotation is 90掳, the valve is fully open. This valve is generally installed horizontally. The clip-on butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by only rotating 90掳, and the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small. That is to say, it has a better control over flow. The butterfly valve has two sealing types: a spring seal and a metal seal. Elastomeric sealing valve, the sealing ring can be mounted on the valve body or attached to the periphery of the disc. If a butterfly valve is required for flow control, it is important in choosing the correct size and type. The structural principle of the butterfly valve is especially suitable for making large diameter valves. Butterfly valves are widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems in thermal power plants.
