Forged steel flanged gate valves are a widely used industrial valve known for their durability and reliability. Here are some key information about forged steel flanged gate valves:

Structure features: The opening and closing part of the forged steel flange gate valve is a ram, the direction of the motion of the ram is perpendicular to the direction of the fluid, and the design can only be fully opened or fully closed, not suitable for flow regulation or throttling. The ram has two sealing surfaces, usually forming a wedge, the wedge Angle varies with the valve parameters, generally 50°, 52°52' when the medium temperature is not high.

Tightness: The sealing surface of the gate valve can be self-sealed by relying on the medium pressure, or by using a forced seal, that is, the gate is pressed to the seat by an external force to ensure the tightness.

Type: Forged steel flange gate valve can be divided into wedge gate type and parallel gate type, wherein wedge gate type is divided into single gate type, double gate type and elastic gate type. The screw position of the valve stem is different, and it can also be divided into open rod gate valves and dark rod gate valves.

Advantages: It has the advantages of small fluid resistance, small erosion and erosion of the sealing surface by the medium, saving power to open and close, the flow direction of the medium is not limited, no disturbing flow, no reducing pressure, simple shape, short structure length, good manufacturing process, wide application range, etc.

Disadvantages: It is easy to cause erosion and abrasion between the sealing surface, difficult maintenance, the overall size is large, the opening needs a certain space, the opening and closing time is long, and the structure is complex.

Installation and maintenance: Check the valve cavity and sealing surface before installation, and do not allow dirt or sand adhesion. The bolts in each connection part should be tightened evenly, and the packing part should be pressed tightly to ensure the sealing of the packing and the flexible opening of the ram. Before installing the valve, the user must check the valve model, connection size and pay attention to the medium flow direction to ensure the consistency with the valve requirements. The gate valve must be maintained regularly, and shall not be collided and squeezed at will, so as not to affect the seal.

Application: Forged steel flange gate valve is suitable for a variety of industrial fields, including petroleum, chemical, food, medicine, electric power, shipbuilding, metallurgy, etc., can be used for tap water, sewage, construction, petroleum, chemical and other pipeline systems as a regulating and intercepting device.

Manufacturer information: For example, Xiamen Gute Valve Manufacturing Co., Ltd. provides detailed information on forged steel gate valves, including their product features and contact information.

Product details: National standard forged steel flange gate valve is suitable for a wide range of pressure, the working temperature varies according to different materials, with different structural characteristics, such as Dalian type reduced diameter design, compared with the same caliber cast steel gate valve, the flow is slightly smaller, but the pressure and temperature range is higher, better sealing performance, longer life.

This information provides a comprehensive overview of forged steel flanged gate valves, including their operating principles, features, advantages, disadvantages, and applications in industry.
