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 valve Standard 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.
