The shuttle valve WVT is a ball poppet
shut-off valve. It has two inlets (port P1
and P2) and one outlet (port A). The
inlet with the higher pressure pushes
the closing element towards the other
inlet. The inlet with the higher pressure is
therefore always automatically connected
to the outlet and the other inlet is shut off.
