Handle Operated Concentric Butterfly Valve

Products Description :

The handle operated concentric butterfly valve is simple in structure, small in size and light in weight, and is composed of only a few parts. Moreover, it can be quickly opened and closed by only rotating 90°, 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, so it has better flow control characteristics.

Product Applications :

It is widely used in pipelines as control or throttling apparatus for supply and drainage pipeline of potable water, seawater, waste water, petrochemical industry, energy and power, shipping, food and drug, natural gas, coal gas, HVAC and fire protection systems as well as the building pipelines.
