Lugged Knife Gate Valves
- Our lugged knife gate valve is bi-directional tight and can therefore be installed into a pipe system independent of pressure direction.
- A fully lugged valve body design and integrated flange gaskets makes it easy to install and also allows end-of-pipe installations.
- With a full bore design this gives excellent flow characteristics and makes it suitable for fluids, sludge and liquids with solids in
suspensions such as water, sewage and bio mass. - This valve has a robust coated and fully lugged valve body in nodular iron, with a gate in stainless steel and polished
edge in order to minimize friction and to lower required operation force. - The valve is supplied with a sealing profile in Nitrile or EPDM and this is reinforced with a steel core. .
- The valve is designed, manufactured, inspected and tested according to pressure equipment directive 2014/68/EU category I and II module A2.
- Size range from DN 50 up to DN 1400.
