Check valve

Sunfab’s anti-cavitation valve is used to minimise the risk of cavitation damage in connection with insufficient inlet pressure. This can occur, for example, in applications with a relatively large rotating mass with a long run-down time (e.g. fan operations). The hydraulic motor must have a defined direction of rotation when using Sunfab’s anti-cavitation valve. The valve can be adapted to both left and right rotation. Function: A check valve between the pressure and return ports opens to ensure a flow of oil to the motor if the inlet pressure to the motor becomes too low. It is therefore important to have a specific back pressure on the return line, which if necessary can be created by means of a back-pressure valve.
