Which of the following best describes the function of a slide valve in a duplex pump?

It controls the intake of air into the piston
It manages the flow of steam for both admission and exhaust
It operates the cooling system of the pump
It adjusts the viscosity of the oil

The correct answer is: It manages the flow of steam for both admission and exhaust

The slide valve in a duplex pump plays a critical role in managing the flow of steam, serving both the admission and exhaust processes. This valve is essential for controlling the timing and amount of steam entering and exiting the pump cylinders, which directly affects the efficiency and performance of the pump. By facilitating precise control over steam flow, the slide valve helps optimize the operation of the pump, ensuring that it operates smoothly and effectively during both the intake (admission) and outtake (exhaust) phases. The other options do not accurately describe the primary function of a slide valve within a duplex pump. Managing air intake, operating the cooling system, or adjusting oil viscosity are separate functions that do not pertain to the core responsibilities of a slide valve in this context, illustrating its specific focus on steam flow management.
