BTD Ball type diverter

The DMN-WESTINGHOUSE ball  type diverter  (BTD) has  been  specifically  designed  to converge or  diverge abrasive products in pneumatic conveying systems. The diverter is also suitable for systems having relatively high pressures  and  temperatures, e.g. thermoelectric power  stations  (coal and fuel oil ash), incinerators, foundries and cement, glass, ceramic, limestone, gypsum and chemical factories.

The diverter  can be  used for  both diverting and converging. When diverting  the product  itself provides the  wear  surface (most  common application). When converging the impact area of the product on the diverter has  been considerably  strengthened (see dimensional drawing).

The BTD is made from ductile spheroidal cast iron and is available in 7 sizes in the ranges 65 - 250.

Product information

The design of the diverter  ensures that the higher the positive pressure, the tighter the seal.This is the result of the ball and seal being pushed firmly into its seating.The seals can be replaced with the valve in place by removing the two side covers.

The valve is operated by using a double acting pneumatic actuator with a 5/2 double acting solenoid and position confirmation switch.

The BTD diverter can be used in systems with positive pressures  up  to  6 bar  g and negative pressures  up  to -0.5 bar  g. The standard configuration can be  used for temperatures from -10 up to +150 °C.
