Lug type butterfly valve features:

  • Connection between the shaft and the disc is more secure and robust.
  • Perfect leak tightness with no intersection between the shaft and the gasket.
  • Reduced pressure loss when the valve is open.
  • low height which allows their installation in areaswhere cover depth is minimal.
  • simplicity of network operation thanks to highly reliablegearbox and actuator mechanisms.
  • ability to use it as a safety valve for the network.
  • perfect watertight seal in the closed position.
  • simple design, low maintenance and perfect reliability

 

Lug type butterfly valve Application:

  • potable water supply pipelines and treatment plants.
  • transportation of filtered and recycled water.
  • irrigation distribution networks.
  • water-pumping stations and hydroelectric plants.
  • nuclear industry, fire safety and storage facilities.

 

Lug type butterfly valveStandard Test :

Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

Seat Test:  1.1 times the working pressure with water.

Special Test: On request, any other test can be carried out according to special instruction by client.
