Cast Iron Wafer Concentric Butterfly Valve

Description

The Cast Iron Pinched Centerline Butterfly Valve is a wafer-type (clamped between flanges) concentric butterfly valve with a resilient seat and stainless steel disc. Its compact body is held between two pipe flanges by through-bolts, making it one of the lightest and most economical shut-off valves available. A notched lever gives quick quarter-turn operation and position locking.
