Installation
Gate valves can be horizontally or vertically installed. The slow and proportional
manoeuvre avoid the water hammer phenomenon. We recommend to pay
attention during the installation phase, above all for the small dimensions,
avoiding forcing the pipe screwing and deforming the sealing seats. Gate
valves can also work in intermediate positions of the stroke, so as to parzialize
the capacity into pipes.
