Installation
Gate valve with female threads. It is suitable for use with cold water, hot
water and steam at low pressure. It satisfies the requirements of PED 97/23/
CE Directive, according to which, it is exempted from CE marking according
to 3.3 paragraph.
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.
