Lug

Production Range:

We manufacture LUG Type valves from DN-50 mm (2") to DN-600 mm (24")

Flange Drilling:

PN-10, PN-16, ASME B 16.5 150 Lbs or ASME B 16.47 A-SERIES 150 Lbs. Any other standard on request.

Standard working pressure:

16 Bar (DN 50-300) and 10 bar (DN 350-600). For higher working pressures, ask our Technical Department.

Temperature Range:

–40ºC to +180ºC (depending on liners and coatings).

As this is a pattern to be usually used with bolts threaded to the body of the valve, it is necessary to take into consideration that the pipe transmits mechanical tension and compression stress which might cause watertightness problems. Therefore, compensation joints or any other elements absorbing these mechanical effects should be used.

Its use allows the valve to be repaired downstream as the valve remains fixed to the upstream flange (See figure bellow).

This valve allows the positioning of other valves or apparatus next to it gaining free space and eliminating accessories.

Due to its design it allows a perfect alignment with the pipe flanges.

When assembling, modifying or repairing the installation, the VAMEIN LUG Type butterfly valve can temporarily work as end of line. Furthermore, the following pressures must never be exceeded:


  • DN-50 mm (2") to DN-150 mm (6") ≤ 5,6 Kg/cm²
  • DN-200 mm (8") to DN-600 mm (24") ≤ 3,5 kg/cm²

For larger Nominal Diameters contact our Technical Department.

Calculation Formula: Working pressure X 0,35 = Maximum valve pressure to work as end of line.

Once the repairs are finished and before returning the line to normal working order, you must assemble the pipe downstream or place a supplementary loose flange so that the valve is between two flanges.
