The DMN-WESTINGHOUSE PTD plug type diverters have been specially designed to route powders and pellets with minimum degradation in pneumatic conveying systems. The PTD plug type diverter is applied in the chemical, pharmaceutical, plastic, food and other related industries.
A smooth passage of product is guaranteed by precision machining, a good sealing and a complete obstruction free passage.
The user friendly fool proof design enables fast in situ internal examination, cleaning and, if necessary, replacement of seals. A quick clean version with easy slide rails is optionally available.
The PTD is designed conform all current legislation regarding safety in the workplace. Consequently there are no moving parts on the outside.
The PTD is available in 7 different pipe sizes: Ø 50, 65, 80, 100, 125, 150 and 200 mm.
Versions conforming to ATEX 94/9/EC are also available.
The PTD plug type diverter consists of an aluminium housing and end covers in which a plug with two pipes is installed. All product contact surfaces are made from stainless steel AISI 316 / DIN 1.4404. Three FDA approved silicone seals guarantee the sealing between housing and plug. The body is pressure tight, so ensuring no leakage to atmosphere. The standard diverter can be used in systems with positive pressures up to 3 bar g (static seals). The sizes 50-150 are optionally available for pressures up to 6 bar g (inflatable seals).
The PTD is supplied with a complete electro pneumatic control system, including solenoids and inductive position sensors.
The plug type diverter can be used for product temperatures ranging from –25 °C up to +80 °C at ambient temperatures of –10 °C up to +40 °C.
