DN50 DN65 DN80 DN100 DN125 DN150 DN200 Wafer Type Ductile Iron Handle Lever Butterfly Valve for Flow Control. Manual lever or gear operator provides simple, reliable, and cost-effective on-off control without power supply. Lightweight wafer body reduces piping load and allows easy handling during installation or replacement. 10-position locking lever enables safe throttling and maintains fixed flow settings in process lines. Self-cleaning disc edge sweeps the seat during rotation, preventing debris buildup and ensuring smooth operation. Available in cast iron, ductile iron, aluminum, and plastic bodies to suit various budgets and media. Quick quarter-turn (0 to 90 degree ) operation allows fast opening/closing, ideal for emergency shut-off situations. Visible disc position indicator on the handle gives clear visual confirmation of valve status at a glance. Replaceable elastomer liners (NBR/EPDM/Viton) allow easy field refurbishment, extending valve service life. Low operating torque reduces handwheel or lever effort, improving worker comfort during frequent cycling. Universal wafer pattern fits between PN10/PN16 and ANSI 150 flanges, offering broad interchangeability.
