PVC-U Butterfly Valve Classic EPDM Series

PVC butterfly valve 

The butterfly valve is a PVC accessory used to stop or regulate the flow of a fluid through a pipe. This valve increases or decreases the flow by means of a disc called a butterfly. This disc rotates on an axis by means of a plate. This plate has a rod that is connected to a handle on the outside of the valve. By turning the handle, the plate rotates and the opening of the disc and therefore the flow rate is adjusted. 

We have a wide range of dimensions and combinations to adapt the installation to your needs from 63 mm diameter up to 250 mm diameter and in nominal pressures of 10 and 6.
