Description
This cast steel gate valve is commonly used in the pipelines of oil, gas, steam and sea water to cut off medium flow, which applies to working system of high temperature and pressure. The seat gasket made of graphite steel pad can make the working temperature to 400℃.
Cast steel gate valve is a reliable and efficient product used for regulating the flow of liquids and gases. It is made up of sturdy cast steel, which makes it durable and resistant to wear and tear. The valve is designed in such a way that it can handle high-pressure applications with ease.
One of the key features of gate valves is that they are designed with a flexible wedge that can adjust to the changes in temperature and pressure. This helps to ensure a tight seal, even in extreme conditions. The valve also has a bolted bonnet, which makes it easy to service and maintain.
Gate valves are ideal for a wide range of applications, including water distribution systems, oil and gas pipelines, and chemical processing plants. They are also commonly used in steam and power plants, where they help to regulate the flow of steam and water to ensure efficient power generation.
Another advantage of gate valves is that they come in a variety of sizes and configurations to meet the needs of different industries. For example, some designs are compact and lightweight, while others are larger and offer a greater flow capacity.
In conclusion, gate valves are a valuable product that has been designed to meet the demands of different industries. They are reliable, efficient, and can help to ensure the smooth running of various processes. If you are looking for a quality valve to help you regulate the flow of liquids and gases in your operations, then gate valve is an excellent choice.
Advantages
1. The sealing surface of the gate valves are made of stainless steel to prolong the working life.
2. The gate valves are primed before painting and are coated anti-rusty oil on the surface without painting.
3. Cast steel gate valves should be inspected for leakage within two minutes with the maximum test pressure of 18 Bar or 28 Bar for sealing and any leakage is unacceptable, which corresponds to class "A" in accordance with GOST R 54808-2011.
