VEE SHAPE SCREEN®
The STÜWA VEE SHAPE SCREEN® is the perfect solution for
long life wells with frequent regeneration intervals. Due to
its attractive price / performance ratio, this screen offers an
excellent alternative to stainless steel wound wire screens.
The well development is favoured by the conical profile of the
discs. This results in a nozzle effect in the treatment using a
water jet from the inside. The clear discs make it possible to
visually examine the gravel distribution and other installed
components at a later stage.
2
VEE SHAPE SCREEN® are supplied with nominal widths with
Whitworth thread, trapezoidal thread or ZSM connections. We
recommend our sealing system STÜWA Quelltec® for sealing
the top pipes. The tested tightness is at 16 bar.
