Check Valves
Also known as Non-Return Valves, Check Valves are designed to prevent fluid backflow and keep flow in a single direction. Utilizing differential pressure, these valves open and close based on pressure differences upstream and downstream. View Tork Systems catalog of Check Valves below or contact a Marine Valve Expert for more information.
