Unit Overview:
Our rotary valves and diverters have a well-established reputation for being able to handle all kinds of dry powders and granular materials, such as sugar, cocoa, starch, flour, chemical ingredients, lime powder, china clay, fly ash and wood chips. A number of standard rotary valves can be upgraded, depending on the product to be handled.

DMN-WESTINGHOUSE has designed The AL and AXL rotary valves for many applications in the metering and pneumatic conveying of products in powder and granular form. Due to the modular design of this extensive and flexible range of valves many configurations are available, using standard components. The AXL valves are supplied with a larger inlet in relation to rotor volume. They are specifically designed for applications where inlet size is more important than capacity or for handling products with poor flowability.
The USAL rotary valves have been designed by DMN-WESTINGHOUSE for many applications in the metering and pneumatic conveying of products in powder and granular form. Due to the modular design of this extensive and flexible range of valves many different configurations are available, using standard components. The USAL valves are also available with two optional bodies in various material sorts, one having round-round flanges (AL) and one having round-square fl anges (AML). See separate leaflets for further information. The USAL valves are available in 3 consecutive sizes: 200, 250 and 300 covering a capacity range of the rotor from 5,5 to 19 liter per revolution at 100% filling.
With the expense of fish feed it is important that degradation of pellets is kept to a minimum. With the help of DMN-WESTINGHOUSE valves wastage can be greatly reduced, when transporting from silo to fish pens. Our BL and BXL blow through rotary valves have been designed by DMN-WESTINGHOUSE for many applications in the metering and pneumatic conveying of products in powder and granular form. Due to the modular design of this extensive and flexible range of valves many different configurations are available, using standard components. The BXL valve with enlarged inlet is specifically designed for applications where inlet size is more important that capacity or for handling products with poor flowability.
The MALD and MLD medium-duty valves are suitable for applications where valves with outboard bearings would be over specified. The valves give exceptional value for money due to the simple construction and direct drive. The basic construction of the three valves is the same, except for the bodies. The valves are suited for both conveying and metering purposes. They are ideal for vacuum conveying applications, big bag unloading, cyclone applications and general-purpose applications. The MALD valve utilizes the AL-valve body, which has two round flanges and is suitable for powders.
The DMN-WESTINGHOUSE DL dust lock is of a specially designed for filter applications. It can be used with dust filters, cyclones, product separators and dosing systems. The universal flanges are on both sides of the valve are drilled to PN10 and can be used for round-round, square-square and square-round connections. The inlet throat is square, therefore accommodating both round and square outlets frorn the vessel that has to be discharged. The sheer angle inlet minimizes product bridging. The outlet throat of the valve is round so that one can discharge into either a round or square connection.The DL range of valves are available with inlet sizes of 200, 250 and 300 mm and respective capacities of 6, 8.5 and 19 ltr/rev.
The SAL (Sanitary Airlock) is a low capacity rotary valve with a highly polished surface on both the inside and outside. The SAL is specially designed for metering purposes in applications where strict hygienic standards are required. Ease of operation and cleaning make the SAL very suitable for use in the pharmaceutical, food and chemical industries. The complete valve can be dismantled for inspection and cleaned in a matter of minutes, thus reducing eventual downtime and production loss. The SAL is available in 5 sizes: DN50, DN65, DN80, DN100 and DN150, with capacities of 0.07, 0.13, 0.25, 0.8 and 2.5 litre per revolution at 100% fi lling. Larger sizes are available on request.
