Check valve with counter weight is comprised of valve body, valve seat, valve cover, valve pin, valve stem, weight lever, counter, etc.
The weight lever is fixed with a weight at one end, and is fixed with the valve pin at the other end. The valve pin is axially fixed on the valve body, and the valve pin is sleeved with a valve disc. The valve disc, the valve stem, weight lever and the weight work together.
The weight makes the valve disc contact the valve seat to form a seal tightness under the action of gravity. The valve body is provided with a counter weight fixing device for fixing the weight to keep the valve open.
The valve can keep the valve in the open state to prevent the backflow of the medium and the damage of water hammer. It has a long service life and is easy to clean the inside of the valve body.
