Switching performance limits (measured <strong>with</strong> HLP46, ϑ oil = 40 °C ± 5 °C)<br />

Caution!<br />

The specified switching performance limits are valid for use<br />

<strong>with</strong> two directions of flow (e.g. from P → A <strong>and</strong> simultaneous<br />

return flow from B → T).<br />

Due to the flow forces acting <strong>with</strong>in the <strong>valve</strong>, the permissible<br />

switching performance limits may be significantly lower <strong>with</strong><br />

only one direction of flow (e.g. from P → A, while port B is<br />

blocked)!<br />
