1 PRODUCT DESCRIPTION
1.1 INTENDED USE
The pilot controlled NeoFlow pressure reducing valve from GF Piping Systems was conceived for
the automatic pressure and flow control in networks for the supply and distribution of water. The
NeoFlow pressure reducing valve is designed to fit between standard PN10 / PN16 in a wafer-type
arrangement. It is also compatible with ANSI150 class flanges.
Foreseeable misuse: The NeoFlow pressure reducing valve may not be used as a pure shut-off valve.
Media other than water as well as water containing an amount of disinfectant may only be used in
consultation with a contact partner from GF Piping Systems. The use of solid matter in the medium
can affect the function of the NeoFlow pressure reducing valve. For this reason, use is only
recommended with an upstream strainer.
