The aim is to discharge a material flow while keeping a difference between the pressure in the upstream and downstream equipment. This equipment can operate under positive or negative pressure.
The valves operate using two independent chambers which work independently. Their plugs can be flaps, cones or cups and they can be actuated by a pneumatic cylinder or a gear train.
These valves are used in industrial environments to handle dry bulk materials that range from fine powders to larger, irregularly-shaped particles.
Only Uniprest valves have very high leak tightness, which prevents false air and also helps to reduce emissions of particulates into the atmosphere, as well as into the work environment. This outstanding feature follows the Brazilian safety standard NR-12, as a Collective Protection Measure.
