Fig 2144-LF
LUNKENHEIMER Swing Check Valves (Bronze Valves) are ruggedly designed for dependable operation in steam, water, oil, gas and other fluid-handling lines where full, free flow is required. Seats and discs are regrindable. Slight pressure differential is required to open or close disc. Because of the exceptional flow characteristic of these check valves, the valves are selected for maximum flow and retaining requirements. The valves function in horizontal or vertical flow positions.
Discs
Renewable and regrindable. Attached to disc carrier by locknut allowing disc to swivel, insuring a tight seal. Open easily with very low differential pressures.
Side plugs
Serve as bearings for disc carrier pins. Easy to replace.
Seats
Integral and regrindable; precisely aligned for tight, dependable seating.
Bodies
Proportioned for maximum strength. Made of highest quality bronze for strength and corrosion resistance. Large clearances at ends of pipe threads permit tight joints without pipe ends jamming diaphragms, distorting seat, or choking flow.
Caps
To prevent damage and leakage, the collar does not extend beyond the body neck. Wide flats for firm wrench grip. Strong threads for tight joints.
Installation and maintenance
Seats and discs may be reground through downstream pipe end.
