Check valves

Check valve

There are a lot of different types of check valves at lauridsenindustri.com. The general function of the valve is that they only allow fluids to run in one direction. The spring, or also called a ball check valve, seals the valve without having reverse flow. It can do this because it is mounted to a spring that pushes the ball back and makes a sealing. A swing check valve works by having a disk instead of a ball closing the valve. The swing type is also more commonly used when a large check valve is used.

At lauridsenindustri.com we deal with springs in, stainless steel, that are threaded. They have range from 1/4"DN to 4"DN. Welding in stainless steel with a range from 8DN to 100DN.

Our swings are made of Stainless steel with a range of 1/4"DN to 2"DN and in cast iron with a range from 40DN to 200DN. Bigger on request.
