What Is a Dry Powder Valve?

A powder valve is a valve that is used in solid materials handling applications. These types of valves are used in pharmaceutical and chemical industries, and are designed to rotate 180 degrees counterclockwise and clockwise to break up the media containing the powder and dispense it through the valve. This rotation is usually accomplished by pneumatic or electric actuators.

A dry powder valve can be either manually activated or automatically operated, depending on your specific needs. The manual valve has a brass nipple that allows you to adjust the depth of the dip tube. It has a bulb glass burst pressure of 680C and is available in different configurations.

These valves are integral parts of bulk powder handling systems and control the feed into the process stream. The company's application engineers work with customers to understand their process requirements and recommend the best valve solution for their application. Some of the key variables to consider include mounting arrangements, flow control requirements, weight, cleanability/sanitation requirements, and more.

Dry bulk solids have abrasive characteristics that make butterfly valves unsuitable for handling dry bulk solids. The abrasive nature of dry bulk solids erodes the butterfly valve's disc, which can cause significant flow restriction. This can be exacerbated by the valve's soft-sealing disc.
