Rotary air lock and blow through valves have been designed for many applications in the metering and pneumatic conveying of products in powder and granular form. These valves are the result of 30 years continuous development.

An extensive and flexible range of rotary valves is available. Due to the modular design of the valves many different configurations are available, using standard components.

This product line also includes USDA approved models for sanitary use in the food, dairy and pharmaceutical industries. These stainless steel valves are easy detachable in a few minutes and meet the highest hygienic standards.

The drop through type valves are available in 10 consecutive sizes from 100-500mm, covering a capacity range of the rotor from 0.8-230 liter per revolution at 100 % filling. In the 400-500mm sizes the valves can be supplied with square in- and outlet.

The blow through valves are available 150-350mm sizes.

Drive options include chain, direct, air and hydraulic drive.

The standard models are suitable for products up to a temperature of 150 °C and a maximum pressure difference of 2 bar. Special configurations are available to accommodate temperatures between -200 °C and +900 °C.

Configurations pressure shock resistant up to 10 bar g and explosion proof models are also available.

All models offer optimum venting through the large vent holes, standard pre-drilled and plugged on cast iron based versions, optional on stainless steel and aluminium versions.
