    Our handwheel-operated knife gate valves handle a wide variety of fluids in wastewater treatment plants, including sewage, grit and sludge. These wafer- and lug-style valves are commonly used as isolation valves, and can fit into very tight spaces due to their very short face-to-face dimensions.

    Choose resilient seat models for zero leakage, or metal seat models for leakage of about 40cc/minute/inch of valve diameter. Wafer-style valves have a cast-iron body and SS gate; lug-style valves have a SS body and gate.

    Actuated valves are available as special order. Please contact USABlueBook for details.
