1. A urinary catheter system comprising:
a catheter tube having a proximal insertion end and a distal end, the catheter tube defining a lumen extending from the proximal insertion end to the distal end for draining urine from a human bladder; and
a valve connected to, or connectable to, the distal end of the catheter tube, the valve comprising:
a valve housing defining a valve lumen therethrough;
a valve gate coupled to the valve housing and configured to regulate fluid communication through the valve lumen;
an arm movably coupled to the valve housing and positioned distally from the valve gate, the arm configured to extend into the valve lumen and to contact the valve gate to prevent the valve gate from actuating into an open position, and the arm configured to be removed to release the valve gate to allow the valve gate to move or be moved into the open position;
a spring connected to the valve gate, the spring configured to apply a threshold pressure against the valve gate to keep the valve gate in a closed position when the arm is removed from the valve lumen, wherein when a fluid pressure above the threshold pressure will move the valve gate into or towards the open position to allow fluid flow through the valve lumen; and
a lever connected to the valve gate and configured to be manually manipulated to move the valve gate into the open position when the arm is removed from the valve lumen.
