Butterfly Valve, 8"

Wafer Style, GRW Series

Keystone Series GRW Butterfly Valves feature rugged quality construction ideal for most industrial applications involving water, air and dry bulk conveying, etc. These valves are for any service where a drop-tight shut-off with maximum flow area is required. The GR Series replaces the AR Series. The Keystone GR series comes standard with Cast Iron Bodies, 316SS disc and stem, and REPLACEABLE EPDM seats (Buna available). These "Wafer" style bodies are designed for drop-in applications and should be "sandwiched" between flanges or backup rings. Rated pressure up to 230 PSI.

Note that these replaceable seats are not rated for full vacuum (good to 15" Hg vacuum). Valves come standard with locking handle, but bare stem options are available (order with "BARE" suffix – example: KEGRW-20BARE). Larger sizes available than what is shown – call for details. Also available in lug style (GRL Series). See DU GRL Series for air actuated GRL assembled valves.
