The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce slight deformation. In order to improve its manufacturability and compensate for the deviation of the angle of the sealing surface during processing, this kind of gate is called an elastic gate.Our gate valves are built to withstand the toughest conditions. Constructed from high-quality materials that are engineered to resist corrosion, our gate valves deliver long-lasting durability and optimal performance. With a robust construction that is resistant to high temperatures and pressure, you can be confident that our gate valves will continue to operate smoothly for many years to come.

Gate valves are used in a variety of industries, including water treatment facilities, oil and gas refineries, chemical plants, and power plants. They are often used in applications where precise flow control and shut-off are essential. For example, gate valves are commonly used in fire protection systems, where the valve's ability to provide a tight shut-off can prevent the loss of firefighting water.
In summary, gate valves are an essential component of many fluid control systems. With their ability to handle a wide range of applications, provide precise flow control and shut-off, and their durability, gate valves are the perfect solution for industries that require reliable fluid control. Install the right gate valve for your application to enjoy reliable, efficient, and cost-effective fluid control operations.
There are two main types of gate valves: rising stem and non-rising stem. Rising stem gate valves have the valve stem extending out the top of the valve and moving up and down as the valve is opened and closed. Non-rising stem gate valves, on the other hand, have the valve stem threaded internally and are often used in applications where space and accessibility are limited.
One of the main advantages of a gate valve is its ability to provide a tight shut-off. When the valve is completely closed, there is no fluid passing through the valve, which prevents any leaks and unwanted fluid flow. Additionally, gate valves are designed to handle a wide range of temperatures, pressures, and fluid types, making them a versatile option for most industrial applications
