FLUITEK ORSENIGO VALVES, through the know how and experience of Friulco, has incorporated a wide range of engineering products for this application. The required valves are wedge or parallel slide gate valves, swing check valves, globe valves, stop check globe valves. Focus is placed on products for high pressure and high temperature service. The media are high pressure feed water service and/or superheated steam high temperature service (lately approaching 650 degrees centigrade continuous service). The design is based on pressure seal bonnet (also called “autoclave”) ideal for body/bonnet joint sealing at high pressures. Materials and manufacturing process controls for all products which will be used in extremely critical conditions are treated with particular care. In fact, material composition, heat treatment, welding procedures, and manufacturing processes are strictly connected with the safety and life-cycle of product in service. For example, the high temperature steam service valves in modified 9 per cent chrome material (C12A castings, F91 forgings, Werkstoff 1.4903 forgings) and materials for high pressure moderate temperature water lines (Werkstoff 1.6368; 15NiCuMo5Nb).
