Piston Type Pressure Seal Bonnet
The swing check valves and the tilting disc type check valves are not the only ones used in the high pressure, high temperature lines, typical of the power and steam generation industries. The process industry sometime also uses the herebelow described product. FLUITEK ORSENIGO VALVES can offer a piston type check valve line for high pressure, high temperature service. Construction is with Y-pattern (lifting direction inclined versus fluid centerline). Both forged and cast body construction are available.
Piston is either spring loaded or not, depending on customer choice. Ends configuration is quite normally with butt weld ends. Materials are to ASTM/ASME standards or EN standards, either harmonized or not, ranging from carbon steels, to low alloy steels, to austenitic stainless steels, to austenitic-ferritic stainless steels (duplex), to nickel alloys.
FLUITEK ORSENIGO VALVES offers, as a special added on feature, the possibility of simulating the fluidodynamic behavior of this type of valve, determining its proper functioning at certain specified flow rates, with customer furnished data of fluid conditions.
