This is a 4 port, 3 (infinite) position, float center (P port blocked), variable solenoid controlled, pilot operated, spring centered, proportional directional control valve, with onboard electronics (amplifier).

And for our non-North American friends, rather than "float", the center may be described as "A and B connected to T, P port blocked."
