Gate Valve
Gate valve is an opening and closing part of the gate plate, the direction of motion of the gate plate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and fully closed, can not be adjusted and throttled. Gate valves are sealed by contact between the seat and the gate plate, and the sealing surface is usually surfacing with metal material to increase wear resistance. There are rigid gate and elastic gate, according to the different gate, gate valve is divided into rigid gate valve and elastic gate valve.
Description
Gate valves are designed for fully open or fully closed service. They are installed in pipelines as isolating valves and should not be used as control or regulating valves. Operation of a gate valve is performed doing an either clockwise to close (CTC) or clockwise to open (CTO) rotating motion of the stem. When operating the valve stem, the gate moves up- or downwards on the threaded part of the stem.
A | Operating | Large hand wheels for easy operation. Also available with gean-ring, motor actuators,pneumatic or hydraulic actuators for more diffcult services. |
B | Live Load | In services requiring frequent cycling or with high pressure/temperature variations， live loading extends the service life bet-ween maintenanceperiods by requining less frequent packing gland adjustments Belleville springs are employed to provide constant packing gland stress |
C | OS＆Y | Outside Screw and Yoke. Cast steeI gate vaIve yoke. IntegraI with bonnet for 150Lb-8“,300Lb-8“,600Lb-8“,900Lb-4“ ＆ smaII. |
D | BB | Bolted bonnet. Welding bonnet and pressure seal bonnet in services requining frequent cycling or with high pressure/temperature variations |
E | End Connections | A choice of FIanged,RTJ fIanged or Butt weIding end for piping fIexibiIity. |
F | Yoke sIeeve | Extra Iong thread engagement between yoke sleeve and stem provide long thread life. Valves of sizes larger than 150Lb-12“ 300Lb-10“，600Lb-6“, 900Lb/1500Lb / 2500Lb-4“ are regularly providedwith roll bearing yokes |
G | Lantern Ring and | Lantern ring with leak off fitting connection and double packing stack is optionally available for critical services. |
H | Body-to- | A flat face gasket joint is used in the150Lb valves. A male and female joint is used in 300Lb to 600Lb valves. Ring joint is used in the body tobonnet connection in 900Lb ＆ higher rated valves. |
I | Stem | All wedge gate valves are provided with upset forged T-headstems. By forging the T-head, the stem at the stem-wedge connection is stregthended. This design also allows the wedge to self-alingn,eliminating the possibility of bent stem jamming the wedge. |
J | Body-to- | Integral guide rib faces assure selfcentering of wedge. Flexible wedge gate valve has a one-piece,twin-disc wedge, which is designed so thateach half flexes independently. Available in solid,flex split and His desigans. |

Uses of packaging in the steel industry
Protective function
- Prevent steel products from physical damage, such as collision, scratching and extrusion, during transport, storage and handling to avoid affecting the quality and appearance of the products.
- Insulate from external environmental factors, such as humid air, rain, dust, etc., to reduce the risk of rust and corrosion of steel and ensure the performance and service life of the products.
Wooden box packaging
- Use: Mainly used to protect some irregular shape, easy to damage or high requirements for packaging of steel products, such as precision parts and components.
- Specific description: the wooden box is made of thick wooden boards, and cushioning materials, such as foam, air cushion, etc., may be added inside to reduce the impact of vibration and collision on the product.
Anti-rust paper packaging
- Purpose: To prevent rust and corrosion of steel products, especially suitable for storage or transportation in a humid environment.
- Specific description: anti-rust paper usually contains rust inhibitors, can be in contact with the metal surface to form a protective film, blocking the erosion of moisture and oxygen.
Plastic film packaging
- Purpose: To provide basic protection against dust and moisture, commonly used for small steel products.
- Specific description: plastic film has a certain degree of flexibility and sealing, can be tightly wrapped in the product surface, effectively isolate the external environment.
Pallet packaging
- Purpose: To facilitate the stacking and handling of steel products, and improve logistics efficiency.
- Specific description: The pallet is usually made of wood or plastic, the steel products are placed on the pallet, and then the forklift and other tools can be used for handling and loading and unloading.
Factory container packing
- Purpose: It is used for mass transportation of iron and steel products, to protect the products and improve the utilization rate of transportation space.
- Specific description: Containers have a strong structure and good sealing, and can adapt to long-distance transportation and the conversion of multiple modes of transportation.
Anti-rust oil coating packaging
- Purpose: To form a layer of antirust oil film on the surface of steel and enhance the antirust ability.
- Specific description: evenly cover the steel surface with anti-rust oil by brushing or soaking to form a durable protective layer.
Metal Corner Protection Packaging
- Purpose: To protect the corners and edges of steel products from damage during handling and transportation.
- Specific description: Metal corner guards are usually installed on the corners of products, using welding, bolting and other methods to increase the strength and impact resistance of the corners.
Baling Steel's packaging will surely convey to you our dedication to quality. We understand the importance of packaging to the quality of steel products and transportation safety, so we strive for excellence in the selection of packaging materials, so that you do not have to worry about the loss of transportation, and fully feel our professionalism and dedication!
