Besides the well known rotary valves and diverter valves, DMN-WESTINGHOUSE have now incorporated MS Knife Valves into their program. These large valves are suitable for applications in various industries for handling products, such as wood chips and fine minerals. 

Blades
DMN Knife Valves are equipped with both an upper and lower cutter blade, which ensure that the valves do not jam or seize due to the particle size. The V-shaped 10 pocket rotor provides a strong shearing action as the blade enters the bore, which helps the cutting action in many applications.

Use
The valves can be used for charging and discharging into dryers in the particleboard industry, woodchips in the biomass power industry, the minerals industry (cement, mineral processing and recycling), metal industry (extraction systems) and power stations. Some valve types are available conforming to ATEX Directive 94/9/EC and can therefore be used in protective systems.

The wear resistant rotor tips in combination with the chrome plated housing makes the valves very suitable for abrasive applications. The upper cutter blade is easily accessible which makes adjustment very easy and convenient.

Types
The MS valves are available in 12 sizes from 58 to 940 liters at 100 % filling efficiency, and rotor diameters vary between 500 and 1000 mm. The valves are suitable for pressures up to 0,8 bar and a product temperature up to 150 ºC. As standard these valves are directly driven, other drives are available on request. An air purge seal is optionally available.
