Diverter valve for pneumatic conveying

The new ball-type diverter (BTD) from DMN-Westinghouse is designed to converge or diverge abrasive productions in pneumatic conveying systems. It is also suitable for systems with relatively high pressures and temperatures.

When diverting, the product provides the wear surface. When converging, the impact area of the product on the diverter has been strengthened to provide a long and reliable service life. The diverter has been designed to ensure that the higher the positive pressure, the tighter the seal. This is due to the ball and its seal being pushed firmly into its seating. The seals can be replaced with the valve in place by removing two side covers.

The BTD is operated by a double-acting pneumatic actuator with a 5/2 double-acting solenoid and position-confirmation switch. It 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 ranging from –10°C up to 150°C. Made from ductile spheroidal cast iron, the BTD is available in seven sizes, ranging from 65mm to 250mm diameter.
