Which valve type is described as a 4/2-way directional control valve with hand lever actuation and spring return?

• A. 4/2-way directional control valve, solenoid actuated, spring returned
• B. 4/3-way directional control valve, hand lever actuated with recirculating mid position
• C. 4/2-way directional control valve, hand lever actuated, spring returned
• D. 4/3-way directional control valve, double solenoid actuated via piloted signal, spring centered with manual override

Answer: (C)

Understanding valve identification comes down to port/way count, how it is operated, and how it returns to rest. A 4/2-way valve has four ports and two positions, meaning it can connect the pressure source to one of the two work ports while venting the other to drain. When it’s actuated by a hand lever, you manually move it to switch positions. With spring return, once you release the lever, the spring pushes the spool back to its default position. This combination—four ports, two positions, manual actuation, and spring return—fits exactly. The other descriptions describe different actuation methods (like solenoids), different port counts or positions (such as a 4/3-way), or different neutral configurations, so they don’t match.
