Stainless & Steel Check Valves / Swing Valves - 348

A check valve is used to prevent backflow. Some check valves only work when installed in a horizontal manner. Check valves do not have operating mechanisms because the valve operates automatically, depending on the pressure of the flow. In sensitive systems, "cracking pressure" is the back pressure at which the check valve becomes engaged. Stainless Steel valves are used in sanitary, corrosive, or industrial applications where brass valves are not suitable.
