8 inch Butterfly Valve PP EPDM

The Hayward Flow Control BYV44080A0EL000 is a wafer-style butterfly valve built for 8 inch piping systems. Its body and disc are made from glass-filled polypropylene with an EPDM liner. A lever handle provides manual flow control. The valve meets ANSI B16.10, ISO 5752, ISO 5211, NSF/ANSI 372 and ASTM D4101 cell class 85580 standards.

Suited for chemical and water lines up to 150 psi

This valve fits applications needing corrosion-resistant shut-off between 32 and 250 degrees F. It is not for systems exceeding the 150 psi pressure rating or temperatures outside the stated range. Buyers who need a different liner material or an actuated handle should look at other models.

150 psi maximum water pressure decides fit

The pressure rating at the operating temperature is the single specification that confirms whether this valve can handle the system design. Verify the 150 psi limit against your requirements before purchasing.

Questions about this item

What bolt-circle diameter and lug size does the 8 in wafer valve need for mounting?

The valve requires an 11 3/4 in bolt circle with eight 7/8 in lug holes to fit between flanges.

How is the lever handle oriented during installation, and what step is often missed?

Mount the valve with the disc partially open, then tighten flange bolts in a cross pattern so the lever aligns with flow when open.

Which parts of the EPDM-lined PP valve typically need replacement after long service?

The EPDM liner and glass-filled polypropylene disc are the wear items that eventually require replacement.
