English term or phrase: float center valve
explanation
These are the most common spool center options for hydraulic directional control valves in mobile applications for directing fluid in hydraulic system to the machinery.
Closed Center Control Valve
Open Center Control Valve
Tandem Center Control Valve
Float Center Control Valve

A float center valve has an open connection from working ports A and B to the tank. In this configuration, P is blocked, making this a closed center circuit.
//
The float center spool is used in circuits where both work ports are required to be open to tank while in the neutral position. It is used in conjunction with load holding or motion control valves, which themselves necessitate draining of their spring chambers, a function that wouldn't occur with a closed center.

zawór czterodrożny z jednym portem zamkniętym
Explanation:
An open center valve connects all four ports when the valve is centered.

A closed center valve blocks all four ports.

A tandem center blocks two ports, and connects two ports. Usually, it is used to block the A and B ports, and connect the pump to tank. This center is very common in applications like the simple press circuit, to allow the pump's flow to go straight to the tank, rather than forcing it over the relief valve.

A float center blocks a single port and connects the other three. It is usually used to block the pump, and connect A and B to tank.
