The valve seals a pressurized system against loss of air and pressure. Rotary valves make it easier to control the flow of material from bins, hoppers, or silos, onto conveying or processing systems. Applications for rotary airlocks include cement, minerals, grains, plastics, flour, gypsum, lime, coffee, cereals, and pharmaceutical manufacturing

Oct 18, 2017 Example: A rotary valve feeding 100 lbs./min of milk powder with a bulk density of 35 lbs./cu. ft. Rotary valves typically run with efficiencies ranging between 65-85%. Product followability, pressure differential, type of feed to the valve, and rotor design can all affect this

A powder valve, is a type of valve designed for the handling of solid material, like powder and tablets in the Pharmaceutical & Chemical industries. How does a powder valve work? A Powder valve works by rotating 180 degrees clockwise and counterclockwise breaking up the media of powder and dispensing it through the valve

Rotary Valves - Heavy Duty Cleanable HDMC. The HDMC rotary valve is a cost effective solution based on the HDM valves for occasional cleaning of the valve internal. The non-drive end cover can be quickly removed to gain access for cleaning which can be carried out by plant operators without the need for special tools

Typical clearance for airlock rotary valves is 0.1 mm and usually ranges from 0.05mm to 0.25 mm depending on the service expected for the valve (high difference of pressure from each side of the valve or not). This is a very small clearance which explains that rotary valves often suffer of scratches due to contact rotor / stator

Apr 26, 2019 Discharging a food powder produced from a wet mix in a spray dryer is a typical sanitary application for a rotary valve that must meet the mid-level hygiene requirement and can require wet cleaning. To select a rotary valve for this hygiene level, start by following the same mid-level hygiene guidelines for a valve that requires dry cleaning
