Milestone Flanged Ductile Iron Cast Iron Gate Valve
The opening and closing part of Double flange sluice valve is a gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. Gate valves are one of the most widely used valves in today's industrial marketplace. These valves are designed to control the flow of fluid and provide a tight shut-off when not in use. With the ability to handle a range of applications, from low to high-pressure and extra-large diameter openings, gate valves are the ideal choice for many fluid control systems. You can rest assured to buy customized Double flange sluice valve from Milestone. We look forward to cooperating with you, if you want to know more, you can consult us now, we will reply to you in time!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.

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.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.
