WACO slide gates are used extensively within treatment plants to control the flow of water into tanks or through channels and troughs. Standard gates feature 1/4 in. thick aluminum slide plates and handwheel or electric motor operators. Poly-Glide ultra high molecular weight (UHMW) polymer bearing bars integrated into the extruded frames minimize friction and greatly reduce operating force required to open the gate. Neoprene P-seals may be provided to reduce leakage.

The WACO slide gate may be configured for embedment in a concrete channel, mounting to the walls of an existing channel, or mounting at a port or trough opening into a tank. For particularly corrosive applications, slide gates may be fabricated from 300 series stainless steel.
