Squaring the circle
Our knife gate valve VK was developed for all kinds of rectangular or square flange connections. The flange can be customized, as was done with the one in the photo. Two of these valves will soon be installed as horizontal discharge valves in a coal-fired power plant in the Philippines.

Extending the lifecycle
We not only manufacture new valves every day - we also repair existing ones. Our knife gate valves are thus fully operational far beyond their usual service life.

Knife Gate Valve VK with Special Finish
A rare sight among our red Wey knife gate valves with round passage: our VK series for rectangular flanges. Coated on customer request in a special color, which coincidentally exactly matches our Sistag green. The knife gate valve will soon be used in a German brewery.
