Sunfab Hydraulic Anti-cavitation Valve

Sunfab Anti-cavitation Valve

For use with Sunfab SCM series of hydraulic motors. Sunfab’s anti-cavitation valve functions as a check valve between the pressure and return ports, minimizing the risk of cavitation damage caused by insufficient inlet pressure. The valve opens to maintain oil flow to the motor if the inlet pressure drops too low. An example of when cavitation occurs is when a large rotating object such as a fan has a long rundown cycle.

The hydraulic motor must have a single direction of rotation when using this anti-cavitation valve. The valve can be used for both left and right rotating motors. It is also important to have a specific back pressure on the return line.
