Vertical Lift Check
Lunkenheimer Lift Check Valves
Fig 418
Lunkenheimer Lift Check Valves are ruggedly designed for non-return control where pulsating action is present in general service use. Seats are regrindable and discs are regrindable and replaceable. All parts are renewable. Generally used in connection with globe valves because of similarity of flow characteristics.
Discs
Renewable, regrindable bronze; precisely guided above and below the seating faces to prevent cocking.
Seats
Regrindable, integral seats are machined to precisely fit taper of discs.
Bodies
Proportioned for maximum strength, full flow. Large clearances at ends of pipe threads permit tight joints without pipe ends jamming diaphragms, distorting seat, or choking flow. Made of the highest quality steam bronze to resist wear and corrosion.
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
To facilitate removal for inspection or repair, vertical lift valves should be installed near a pipe union. Seating faces can be reground by removing cap and applying screwdriver to slot in stem.
