In the piping systems of a MODU, what type of valve gives the least resistance to fluid flow when fully open?

Question 1 of 27070

In the piping systems of a MODU, what type of valve gives the least resistance to fluid flow when fully open?

🔍 Key Concepts

• Flow path and internal shape of each valve type (butterfly, gate, globe, packless) • Difference between throttling (flow control) and full open / shutoff service • How much the valve body and disc/plug obstruct the line when fully open

💭 Think About

• For each valve type, picture the inside of the valve when it is fully open—how straight or obstructed is the flow path? • Which valves are mainly designed for throttling (controlling flow rate) rather than offering minimum resistance when wide open? • Among the options, which valve allows fluid to pass with almost the same area and direction as the connecting pipe when fully open?

✅ Before You Answer

• Identify which valve type provides an almost straight-through flow path when wide open • Eliminate any valve whose disc, plug, or body shape remains in the flow stream when open • Recall which valve is not ideal for throttling but excellent for low pressure drop in piping systems
