Bidirectional Knife Gate Valve – Series 767, Heavy-Duty Slurry Valve with Replaceable Sleeves

The Series 767 Bidirectional Knife Gate Valve is engineered for high-performance isolation in highly abrasive and corrosive slurry services. Designed with full-port replaceable rubber sleeves, this valve provides bubble-tight shutoff in both flow directions, eliminating the need for downstream isolation.

The rugged cast body and fully guided gate ensure consistent operation under high cycling and severe process conditions. The Series 767 is widely used in mining, chemical processing, wastewater treatment, and pulp and paper industries, where solid-laden or corrosive fluids are common.
