New Gravity Plug Diverter DMN-WESTINGHOUSE
The new DMN-WESTINGHOUSE GPD is a two-way, demountable gravity diverter valve and is ideal for system installations that require frequent cleaning with minimum downtime. Design allows fast disassembly in installed location and easy access to all product-contact surfaces. The GPD is available in 4 sizes and in cast iron, aluminium or stainless steel.
The GPD diverts gravity fed material to either of two lines by a rotating blade that swings through 120° to fully close off the unused port. This is done with extremely close, machined tolerances between rotating blade and body. Material flow through the valve is unrestricted with no ledges or dead spots and the product flow can be changed on the fly with most powders. The valves are manufactured in a range of finish options, including sanitary specification.
Comparable fabricated gravity flap diverters normally have a polyurethane flap clamped between two metal plates to provide the seal. The disadvantage of this construction is that seal material can break off and cause leakage, as well as contaminating the product. There is also a risk that nuts and bolts could become undone and also contaminate the product as well as damaging equipment down stream. The GPD however has a rotor manufactured as a one piece fabrication, therefore eliminating these risks.
The GPD diverter is available with a cast iron, aluminium or stainless steel AISI 316 housing, in which a stainless steel AISI 316 plug is installed. The diverters are manufactured from a rugged cast design, which guarantees stability and a problem free operation. The GPD is available in 4 sizes: 150, 200, 250 and 300 and can be used for product temperatures ranging from -10 °C up to +80 °C. Options for higher temperatures are available on request.
