(anti-cavitation valve may be needed).
Uni rotational M5AS* Motors are fitted with an internal anti-cavitation
valve.

An anti-starve check valve can be screwed directly onto the B port of the
uni-rotational motors, to ensure the minimum replenishment pressure during
deceleration phases of high inertia systems (i.e. fan drive).
