How does a latco valve work?

A latco valve, also known as a check valve, is a mechanical device that allows fluid to flow in only one direction. It consists of a valve seat, a valve disc, and a spring. The valve seat is a stationary part that is installed in the pipe. The valve disc is a movable part that is positioned in front of the valve seat. The spring is used to hold the valve disc in place.

When fluid flows in the intended direction, the pressure of the fluid forces the valve disc to move away from the valve seat, allowing the fluid to flow through. When the fluid flow stops or reverses, the spring pushes the valve disc back against the valve seat, blocking the flow of fluid.

The most common type of latco valve is the swing check valve. In a swing check valve, the valve disc is hinged on one side and swings open and closed like a door. Other types of latco valves include the lift check valve, the ball check valve, and the diaphragm check valve.

Latco valves are used in a variety of applications, including plumbing, heating, and cooling systems, as well as in industrial processes. They are used to prevent backflow of fluid and to protect pumps, compressors, and other equipment from damage.
