When it comes to plumbing, there isn’t just one option to choose from when deciding which valve is best for your needs. To begin, you need to understand the many types of valves before deciding on the ideal one for your needs. Let’s get this party started, shall we? In the plumbing system, there are five main valves, but today, I’ll be focusing on the gate valve.
Gate valves are built with a metal gate that is wedge-shaped that will be used to stop or open the flow of water. The metal gate can be raised or lowered and is used to allow the flow of water. This valve is probably the most widely used in the world of plumbing. Gate valves are highly useful as they are able to handle many types of fluids like water, gas, oil and many more. These valves cannot control the amount of water that flows and can only control whether the water flows or not.
Difference Between Gate Valve and Butterfly Valve
The gate valve’s sealing performance is good, therefore it’s frequently used in pipelines that demand tight sealing but don’t require frequent switching, and it’s used to turn off the circulating medium. The flow rate cannot be controlled using the gate valve. Furthermore, because the gate valve’s opening and closing speeds are moderate, it is not suited for pipelines that require emergency shutoff.
Butterfly valves are utilised more frequently, and they can be employed not only for truncation but also for flow rate adjustment. Additionally, the butterfly valve opens and closes swiftly and can be opened and closed repeatedly, making it ideal for situations needing quick opening or cutting.
Butterfly valves are smaller and lighter than gate valves, hence a more space-saving wafer type butterfly valve is recommended in some applications when installation space is limited. Butterfly valves are the most commonly used large-diameter valves, and they are also suggested for conveying medium pipes containing minute particles of pollutants. In various operating settings, butterfly valves have steadily displaced other types of valves, making them the first option for many users.
The price of a gate valve is more than that of a butterfly valve under the same pressure and calibre. The diameter of the butterfly valve, on the other hand, can be made quite big, and the cost of a large-diameter butterfly valve is comparable to the cost of a gate valve.
There is a difference between the gate valve and the butterfly valve in terms of movement direction and manner. Furthermore, because the gate valve can only be fully open or fully closed, its flow resistance is lower in the totally open position; in the fully open state, the butterfly valve’s thickness causes resistance to the flow medium. Furthermore, because the gate valve’s opening height is high, the opening and closing speed is slow; but, because the butterfly valve can only be opened and closed by rotating 90 degrees, the opening and closing speed is fast.
