Butterfly valve spacers are usually made from HDPE material to suit DN250, DN200, DN160, DN100 valve sizes. Butterfly Valve Spacers are used to create a space opening for a butterfly valve disc between pipe flanges in a pipeline. Sometimes butterfly valves cannot open fully without a HDPE Butterfly Valve Spacer on both sides of the valve. The HDPE Butterfly Valve Spacer allows the valve disc to open when installed. Sometimes when thick PE pipe is used, a butterfly valve spacer will also be required for this same purpose.
