Forged Steel Gate Valve Flanged End
✧ Description
Forged steel gate valves are commonly used in industrial applications due to their robust construction and ability to withstand high pressure and temperature conditions. They are often preferred for applications in the oil and gas industry, power plants, and petrochemical plants. Here are some key features and advantages of forged steel gate valves:Strong and Durable: Forged steel gate valves are manufactured using a forging process, which makes them exceptionally strong and resistant to mechanical stresses. This makes them suitable for demanding environments where durability is critical.High Pressure and Temperature Resistance: These valves are designed to handle high-pressure and high-temperature applications, providing a reliable flow control solution in challenging operational conditions.Excellent Sealing Properties: They offer good sealing properties, effectively preventing leakage when the valve is closed. This is crucial for maintaining system integrity and preventing fluid loss.Minimal Pressure Loss: When fully open, forged steel gate valves offer minimal pressure loss, allowing for efficient flow regulation and reduced energy consumption.Versatility: They are suitable for a wide range of fluids, making them versatile for various industrial applications.Compliance with Standards: Forged steel gate valves are often designed and manufactured in compliance with industry standards, ensuring their reliability and safe operation.Overall, forged steel gate valves are valued for their strength, durability, high-pressure and temperature resistance, excellent sealing properties, and versatility, making them a preferred choice in demanding industrial settings.
✧ Features of API 602 forged steel gate valve
1.The structure is simpler than the gate valve, and it is more convenient to manufacture and maintain.
2.The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the sealing surface of the valve body when opening and closing, so the wear and scratch are not serious, the sealing performance is good, and the service life is long.
3.When opening and closing, the stroke of the disc is small, so the height of the stop valve is smaller than that of the gate valve, but the structural length is longer than that of the gate valve.
4.The opening and closing torque is large, the opening and closing is laborious, and the opening and closing time is long.
5.The fluid resistance is large, because the medium channel in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
6.Medium flow direction When the nominal pressure PN ≤ 16MPa, it generally adopts forward flow, and the medium flows upward from the bottom of the valve disc; when the nominal pressure PN ≥ 20MPa, generally adopts counter flow, and the medium flows downward from the top of the valve disc. To increase the performance of the seal. When in use, the globe valve medium can only flow in one direction, and the flow direction cannot be changed.
7.The disc is often eroded when fully open.
✧ Advantages of API 602 forged steel gate valve
During the opening and closing process of the forged steel globe valve, because the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, it is wear-resistant.
The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
