Dump Valves


A dump valve (also known as a double dump valve, flat gate valve, or double flap gate valve) controls the rate of material flow through a system more efficiently than a rotary valve. Because there are two gates, one of which is always closed, the pressure drop from inlet to outlet is always maintained. A dump valve endures much less wear and tear than a regular rotary valve, making it last longer and keeping maintenance costs down.

Our dump valves are available with pneumatic, gravity and electric operators. These valves are widely used in the following industries: cement, fly ash, iron ore, paper, and bulk powders.
