Description:
Rotary airlock valves are also called rotary feeders, rotary valves, or just rotary airlocks. Used in both pressure style and vacuum style pneumatic conveying systems, these valves serve as a "lock" to prevent air loss while simultaneously performing vital material handling functions. Though simple, the rotary airlock valve is a critical component to the efficiency of a conveying system.
Rotary airlock feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used. Typical materials include: cement, ore, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc.
Industries requiring this type include cement, asphalt, chemical, mining, plastics, food, etc.
Rotary feeders are ideal for pollution control applications in wood, grain, food, textile, paper, tobacco, rubber, and paint industries, the Standard Series works beneath dust collectors and cyclone separators even with high temperatures and different pressure differentials.
We will continue to adhere to the customer is god, adhere to the customer service as the first brand of the enterprise. Dear business friends, book is willing to use the most sincere heart, the best service and your sincere cooperation
Low leakage
0.08MM ~ 0.1 MM . The right production can ensure air lock .So the production can meet your satisfaction
Casing
Cast casing is strong with QT600 standard raw material .High quality make sure rotary valve have long working life
Closed end Rotor
Closed end rotor can protect rotary valve body and make air leakage as small as new
inspection Windows
Transparent PMMA material help you fast inspection with production.Easy to manage.
Sealing
Teflon seal and mechanical seal.Protect bearing for damaging and help with sealings.
Anti-jam Rotor
Anti-Jam Rotor help rotary valve without jam ,especially when bulk material going through .
