SHORT NOZZLES – STANDARD SIZE

The modern design of these nozzle offers the convenience of a more rational alignment system, with a copper seal used between nipple and nozzle tip. The nozzle efficiency is enhaced by means of a carefully designed flow stabilizer, which minimizes turbulence due to sharp direction change at the inlet from the main manifold. Provision is also made for a filter to be mounted at the nozzle inlet, minimizing nozzle clogging and abrasion.

ASSEMBLY PARTS

WELDING NIPPLES

ZWB

HW nozzles can be assembled on a variety of different nipples, with the same inlet, but with different lengths. The precision machined nipple inlet port assures precise positioning of the nozzle flat fan jet to the specified offset angle value of 15° with regard to manifold center line. This makes it possible to obtain uniform impact distribution yielding better decaling results.

FLOW STABILIZER

XHW

The flow stabilizer is a critical component for proper descaling, by reducing flow turbulence losses, a larger fraction of the water flow energy can be used for generating impact on the surface to be descaled. The design consists of a cylindrical brass body with a polished inner surface, housing a cast stainless steel flow stabilizer which straightens the liquid path to minimize turbulences. Different length nipples are available, with or without inlet filter. The codes always include a multifin flow straightener.

LOCKNUTS

VAW B100 B1

 

VAW D100 B1

The VAW B 100 B1 and VAW D 100 B1 locknuts for ZWB series descaling nipples have been designed profiting from a large experience on the field. The sturdy design and the generous dimensions give the maximum protection to the nozzle and the nipple thread. One lucknut size fits all standard size ZWB series nipple of any length.

 

 

 

GASKET

VDA 24C1 T3

The VDA 24C1 T3 round gasket provides proper assembly between nozzle and nipple. One size fits all standard size ZWB nipple types.
