2 STEAM EXTRACTION / COLD REHEAD ACTUATED CHECK VALVES Application The non-return swing check valves are special valves which prevent a working medium backflow in a pipeline of steam turbine. Each check valve is designed for design conditions. Working medium Water, steam, air, gases and other non-aggressive liquids. The range of working temperature 40 C 570 C. Technical description The non-return swing check valve is designed as a double-eccentricity butterfly swing check valve. The body is fabricated with fully penetrated welds. The check valves disc is a fabricated as well and is placed in friction bearings on the shaft. A counter-weight is attached to the spindle to balance disc weight. This weight is places in a separate pressure-closed chamber. The balancing of the disc assures minimum head loss through valve up to 1%. As a standard the valve is equipped with actuator, which guaranteed function of quick closing and hand lever is there for control of check valve function when turbine is out of service. The actuator an d lever are placed on separate shafts so that their passive friction does not affect the function of the valve. Operation Self-acting, safe closing of valve disc is reached by auxiliary drive (pneumatic/hydraulic actuator). The type of actuator is acc. To customers specifications. Testing The valves are tested acc. To EN / ISO 5208 or acc. To API 598. Sizes Pressure Sizes : 2 64 Pressure Class : PN 10 PN 250 / ASME #150 - #1500
