SDX® V

The SDX® V features an 8 part construction and is the world’s most user friendly spray drying nozzle,requiring only hand tight engagement of the nozzle body into the adaptor throughout the pressure range. The SDX® V also features an improved wear life / performance and effortless maintenance for the lowest cost of ownership.

Features and Benefits

  • Wear benefits are positively retained during assembly.
  • Compatible with current SDX® range.
  • New internal design reduces pressure loss through the nozzle.
  • Smaller and lighter compact design which is more durable, easy to clean and can be rapidly stripped down and reassembled.
  • No wrenches or tools are required to install the nozzle.
  • Minimal friction due to nozzle design permitting 10-20% lower operating pressure than conventional slotted distributor nozzle for equivalent atomization quality.
  • Extended pump life due to lower operating pressure.

Construction and Materials

  • 5 piece construction with 'O' ring seals.
  • Nozzle body and adaptors are available in 316 Stainless Steel.
  • Wear parts are in Tungsten Carbide.
  • O-rings are in Silicone or Viton.
  • O-ring seals allow assembly and disassembly without tools.

Order Example

  • Please indicate all component parts and materials when ordering.

SDX® V Assembly Procedure

  • Place the nozzle body thread side up on a flat surface
  • Insert the orifice seal
  • Place the orifice disc inside the nozzle body with the orifice nose i.e. :the smallest diameter first inserted into the body orifice.
  • Place the swirl chamber on top of the orifice, with the larger diameter flat surface (swirl end) in contract with the orifice disc.
  • Ensure that the retaining disc o'ring is fitted onto the retaining disc.
  • Push the retaining disc into the body until the unit pressed against the back face of the swirl chamber. At this point the retaining disc o' ring will have locked into position with the corresponding groove in the nozzle body.
  • Place body seal into body seal groove positioned above the threads on the outside of the body
  • Pick up the assembled unit and screw into the female adaptor
  • Hand tighten the assembly

Assembly

  • Place Nozzle Body (A) thread side up on a flat surface
  • Insert the Orifice O-Ring (B) into the Nozzle Body (A)
  • Insert the Orifice Disc (C) in to the Nozzle Body (A) with the ‘orifice nose’ (the small diameter section of the orifice ) inserted first so that the tapered inlet section can be seen.
  • Place Swirl Chamber (D) on top of the Orifice Disc (C) with the ‘swirl profile’ located against the back face of the Orifice Disc (C)
  • Ensure that the Retainer O-Ring (E) is fitted onto the Retaining Disc (F)
    Push the Retaining Disc (F) into the Nozzle Body (A) until unit is pressed flat against the back face of the Swirl Chamber (D) and Nozzle Body (A)
  • Place the Body O-Ring (G) into the body o-ring groove positioned above the threads on the outside of the Nozzle Body (A)
  • Pick up assembled unit and screw into Female Adaptor (H), hand tighten

* Specify orifice size and swirl chamber suffix from capacity chart, on pages 14-15

* Standard Swirl Chamber uses Standard Retainer W195490013 or Crown Retainer W209700001 * Flat Back Swirl Chamber uses Cross Milled Retainer W198300003 or Crown Retainer W209700001 * Open Swirl Chamber uses Crown Retainer (Various Sizes) * Crown Retainer Part Numbers to be used with Open Swirl Chamber

Delavan can offer a range of interface adaptors for the SDX® V nozzle. These can be used when converting from previous SDX® nozzles over to the new SDX® V nozzle. The interface adaptors are there to ensure that the same overall nozzle length of nozzle assembly is achieved.

SDX® V Spray Dry Nozzle Flow Rate Charts

Orifice sizes ranging from 0.016” – 0.250” in increments of 0.001” Swirl Chambers ranging from SA (0.76mm) to SM (16mm). The Orifice and Swirl Chamber sizes below show an example of some possible combinations. with over 220 Orifice sizes and 10 Swirl Chamber variants allows us to find a combination to suit your droplet size, flow rate and spray angle requirements. All spray angles are based on water at a pressure of 1000 psi (69 bar). The Mini SDX® has a nominal spray angle of 70º- 75º due to it’s unique cone faced orifice.
