Heavy Duty Slurry Ball Check and Lockout Valves

Heavy Duty Slurry Valves have a unique design of a ball check valve that can easily handle suspended solids while also incorporating a hand wheel mechanism to lock the ball on the seat in the closed position.

Lockout is via a chain on the hand wheel, this combination is widely accepted to be far safer practice than the standard swing check or traditional non return valves.
