Why Choose A Gate Valve Over A Ball Valve For Flow Control
2025-09-01
When it comes to flow control in pipeline systems, one common question we encounter is whether to use a gate valve or a ball valve. While both have their advantages, the choice ultimately depends on the application. In many industrial settings, a gate valve is preferred for its reliability and performance under specific conditions.
At LYV®, we have engineered high-performance gate valves that excel in applications requiring full flow or complete shut-off. Unlike ball valves, which are ideal for quick on/off operation, gate valves provide a tight seal and minimal pressure drop when fully open. This makes them particularly suitable for high-pressure and high-temperature environments.
Key Advantages of LYV® Gate Valves
-
Low Pressure Drop: When fully open, the gate retracts completely into the bonnet, allowing straight-line flow with minimal resistance.
-
Tight Sealing: The wedge-shaped disc provides excellent sealing in both directions, reducing the risk of leakage.
-
Durability: Manufactured from robust materials such as ASTM A216 WCB, our valves withstand demanding conditions.
-
Bi-Directional Flow: Suitable for applications where flow direction may change.

Frequently Asked Questions About Gate Valves
What is the primary function of a gate valve
A gate valve is designed for on/off control rather than flow regulation. It should be used either fully open or fully closed to avoid erosion of the disc and seats.
Can a gate valve be used for throttling
No. Using a gate valve for throttling can cause vibration and damage to the sealing surfaces due to partial opening. For throttling, globe or control valves are more suitable.
How does a gate valve compare to a ball valve in high-pressure applications
Gate valves are often preferred in high-pressure systems because of their ability to provide a tighter seal and lower pressure drop when fully open compared to ball valves.
