Products Details

The forged steel flanged gate valve is a critical valve in industrial applications and is known for its outstanding strength, durability and reliability. The following is the introduction of forged steel flange gate valve in Chinese:

Structural features: Forged steel flanged gate valves with integral forging body and internal components, this integrated forging process makes the valve has a very high density and non-permeability, compared to cast or welded steel valves, its strength is higher. The gate of the valve is a rectangular or wedge-shaped disc, which can be completely withdrawn from the valve wall through the operation of the valve stem and the hand wheel to achieve full flow flow without obstruction.

Advantages: Forged steel flanged gate valves offer several advantages, including superior strength, high temperature resistance, minimal leakage, reliable operation and tight closing performance. These characteristics make them ideal for use in industrial applications with high temperature, high pressure and corrosive media.

Application: Forged steel flange gate valve is widely used in steam pipeline, high pressure system, chemical/petrochemical equipment, water, hydropower, district heating system, nuclear power and oil and gas pipeline. They are preferred in long-term service where robust, leak-free performance is required.

Materials and Manufacturing: According to API 602 and ASME B16.34, forged steel flanged gate valves are designed and manufactured in a variety of materials, including carbon steel, stainless steel, nickel alloys and bronze, to accommodate different temperature, pressure and media characteristics.

Sealing performance: The sealing surface of forged steel flanged gate valves can be metal to metal or with reinforced gaskets, seals or coatings to ensure a tight seal when closed to prevent reverse flow and leakage.

Installation and maintenance: The installation and maintenance of forged steel flange gate valves need to pay attention to some matters, such as the handwheel, handle and transmission mechanism can not be used for lifting, and collision should be avoided. The double gate valve should be installed vertically, and the gate valve with a bypass valve should be opened before opening to balance the pressure difference between the inlet and outlet and reduce the opening force.

Product Specifications: Forged steel flanged gate valves are available in a variety of specifications and sizes for different industrial needs. For example, the national standard forged steel flange gate valve provided by Shanghai Quanhang Valve Manufacturing Co., Ltd. is suitable for the pressure range of 1.6~42.0MPa and the working temperature of -29~425℃, which is suitable for a variety of media.

Manufacturers: Some of the leading manufacturers in China, such as Xintai Valve, offer high quality wrought steel flanged gate valves, which are known for their durable design and strict quality control.
