B5-RLO4 - 4" MATCO Ductile Disc, Lever-Op Butterfly Valve

The B5-RLO4 MATCO 4" Ductile Disc Lever-Operated Butterfly Valve is a workhorse valve for 4" irrigation and industrial pipeline applications. The ductile iron disc provides long-lasting durability and corrosion resistance, while the lever operator with lock plate allows quick shutoff and the ability to secure the valve in any position — open, closed, or throttled.

The wafer body design fits between standard flanges for a compact installation, making the B5-RLO4 a versatile choice for main line shutoff, field splitting, and flow regulation in agricultural irrigation systems.
