Y-Swing Check
Lunkenheimer Swing Check Valves
Fig 554Y
Lunkenheimer Swing Check Valves are ruggedly designed to afford protection against reverse flow in steam, water, oil, gas and other fluid lines. Discs are renewable and seats may be reground without removing valves from the line. Valves function in either vertical or horizontal position. Slight pressure differential is required to open or close disc.
Discs
Renewable. Free acting in any position and swivel on disc carrier for even wear at all points of seating faces.
Side Plugs
Renewable. Serve as bearings for disc carrier pins, easy to replace.
Seats
Regrindable, integral seats can be restored to seat tightness without removing from line.
Bodies
Heavy walls for maximum strength. Full flow area is equal to connecting pipe. 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.
Maintenance
To regrind seat without removing from line, remove plug in upper part of body and apply screwdriver to slot in top of disc.
