An ideal valve for power stations, the high temperature alloy flexible wedge gate valve impresses with its outstanding performance and reliability. Designed to withstand extreme temperatures, it offers exceptional resistance to wear and tear, making it highly durable in demanding applications. Its flexible wedge ensures a tight and secure seal, providing peak performance even at high pressures. If you're looking for a valve that delivers superior quality and precision, the high temperature alloy flexible wedge gate valve is the perfect choice.

Product Information

The integral direct-cast valve, known as the high pressure and high temperature gate valve, is designed to connect to flanges. It serves a crucial role in various pipelines that operate under pressure levels up to 16.0Pa, handling substances like water, steam, and oil. The valve features a valve cover in the middle, ensuring exceptional sealing performance even when exposed to extreme temperatures and high pressures. To enhance durability, the sealing surface on the upper part is constructed using hardfacing carbide, which provides remarkable resistance against wear, high temperatures, corrosion, and lasting performance. Furthermore, the valve rod surface is subjected to a corrosion-resistant nitriding treatment, making it highly resistant to corrosion and scratches. By rearranging the provided information, we can appreciate the key features and benefits of the high pressure and high temperature gate valve.

Located on the valve cover, the device responsible for the operation of opening and closing high pressure and high temperature gate valves comprises various components including a specialized motor for the valve, a reduction gearbox, as well as manual and electric switch settings. To ensure the valve's safety in case of a failure in the travel control mechanism, the valve switch is regulated by the travel control mechanism itself.

ASME standards specify a pressure rating system that ranges from Class 150 to Class 2500. These rating classes, including Class 300, Class 600, Class 900, Class 1500, and Class 2500, are designed to indicate the maximum allowable pressure that a particular valve or piping system can withstand without failing. The higher the class rating, the greater the pressure the system can withstand. It is important to choose the appropriate pressure rating for the particular application to ensure safe and efficient operation.

working principle

In a wedge gate valve, the gate serves as both the opening and closing mechanism, moving perpendicular to the fluid flow direction. However, it can only be fully opened or fully closed, making it unsuitable for regulating or adjusting flow. To operate the valve, the valve stem is raised or lowered using a rotating handwheel.

Both the open rod wedge gate valve and the dark rod wedge gate valve fall under the two types of wedge gate valves. In the case of the rising stem wedge gate valve, the stem is responsible for the upward and downward movement, while the stem nut remains fixed. On the other hand, the dark stem gate valve operates differently as the stem nut moves up and down to facilitate the opening and closing process, with the stem being fixed in place.
