Which 4/3-way valve configuration includes a hand lever actuated with a recirculating mid position?

• A. 4/3-way directional control valve, hand lever actuated with recirculating mid position
• B. 4/2-way directional valve, solenoid actuated
• C. 4/3-way directional control valve, double solenoid actuated
• D. 4/3-way valve with fixed mid position

Answer: (A)

The key idea is a three-position, four-port directional valve that is operated by hand and has a center position designed to recirculate fluid. A 4/3-way valve provides two work ports plus P and T, allowing flow to be directed in two directions and a center position that can route fluid back into the circuit rather than stopping it. A recirculating mid position means that when the lever is in the center, the internal paths allow fluid to circulate rather than deadhead the pump or lock the circuit, giving a safe, neutral, low-load condition. The hand lever aspect specifies manual control, which is typical for this configuration. The other options describe different actuation methods (solenoids) or different center behavior (fixed mid or a 4/2 valve), which do not match the stated combination.
