DMN-Westinghouse products

The MZC rotary valves have been widely used in sanitary applications (Dairy execution) as well as many other applications. The unit has an easy Removeable rotor which can be removed within a few minutes to facilitate inspection and cleaning. The configuration with direct drive has a very narrow construction. The direct drive, in conjunction with a frequency inverter, results in a very flexible, safe and maintenance free unit (no chains or grease). The extraction mechanism offers a high degree of operator safety and gives the line operators considerable flexibility in cleaning and maintaining the equipment between runs. Moreover the stability of the extraction mechanism ensures that the rotor can be easily moved in and out of the housing without damaging the housing or the rotor blades.

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 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 AL and AXL valve range includes USDA Dairy Accepted models and versions conforming to the EC 1935/2004 directive for sanitary use in the food and pharmaceutical industry. These stainless steel valves are easily detachable within minutes and meet the highest hygienic standards.

The AML rotary valves have been designed for many applications in the metering and pneumatic conveying of products in powder and granular form. The AML valves can also be used as a transition piece from round to square and vice versa. The AML valve range also includes USDA Dairy Accepted models and versions conforming to the EC 1935/2004 directive for sanitary use in the food and pharmaceutical industry. These stainless steel valves are easy detachable in a few minutes and meet the highest hygienic standard. The AML valves are available in 7 consecutive sizes from 100-400, covering a capacity range of the rotor from 0,8 to 58 litre per revolution at 100% filling. Drive options include chain, direct, air and hydraulic drive.

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 degredation 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 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 stricht  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.

The GL rotary valves are specially designed for gravity feeding and pneumatic conveying of granular products. The configuration of the body and rotor has been developed specifically to minimise degradation whilst retaining the best possible pocket filling efficiency. The special inlet construction minimizes chopping of product. The built-in inlet sheer protector ensures optimal rotor pocket fill. The GL is available in 3 different body configurations: all stainless steel, stainless steel body with alumium end covers and all aluminium. Te full end disc-rotor is made of 316 stainless steel. The GL valves come in 5 sizes, covering a capacity range from approximately 5 to 79 liters per revolution at 100% filling.
