Double Flap Valve - Stainless Steel, Mechanically Operated, Electrically Operated, Pneumatically Operated | Non-wearing Seal, Extreme Temperature Resistance, Suitable For Pneumatic Conveying Systems, Abrasive Materials Handling

UNICON provides a complete line of dump valves (also known as double dump valve, or double flap valves) suitable for air lock applications. Similar to the rotary airlock valve, the dump valve is used in pneumatic conveying systems, dust control equipment, and as volumetric feed-controls to maintain an even flow of material through processing systems. In a dump valve, however, the flow control is accomplished through two chambers. UNICON dump valves / double flap valves offer a non-wearing seal and will operate flawlessly under all types of continuing process conditions. This would include applications with extreme temperature ranges, abrasive, corrosive materials and high-pressure differentials. We offer a full line of double flap valves.

They are commonly used wherever dry solids need to be moved between areas of differing air pressure. UNICON manufactures rotary airlock feeders and double dump valves which can handle a variety of materials and pressures. Rotary Airlock Feeders and Double Dump Valves are typically constructed of carbon or stainless steel with hard surfacing of the internal components as required for the particular application.

UNICON provides three types of dump valves / double flap valves as mechanically operated valves, electrically operated valves and pneumatically operated valves. In the case of mechanically operated dump valves the counter weight / springs gives the force for the movement of the flap.
