New DMN-WESTINGHOUSE High Pressure valve beats air leakage

At the Powtech DMN-WESTINGHOUSE will present its newly designed HP high pressure rotary valve. This valve has a very important advantage in air leakage: the special configuration of the body and rotor does not only protect product against degradation, it also does not allow any axial air leakage. This means that this valve has an air leakage reduction of one third against other standard high pressure valves. The DMN-WESTINGHOUSE HP rotary valves with specially designed inlet are very suitable for applications in the metering and pneumatic conveying of granular formed products under a high pressure of maximum 3.5 bar g. The configuration of the body, rotor and seals has been specifically developed to minimise degradation of the product which runs through it, whilst retaining the best possible pocket filling efficiency.
