API600 4" 600LB Cryogenic Carbon Steel LCC Flanged Gate Valve
Product Features
Excellent cryogenic performance: The valve body is made of cryogenic carbon steel and undergoes a special heat treatment process. It can withstand extremely low temperatures, ensuring the strength and toughness of the valve under cryogenic working conditions and preventing deformation or cracking caused by temperature changes.
Reliable sealing: The sealing surfaces of the gate and the valve seat are overlaid with Stellite cobalt-based hard alloy by welding, which has the characteristics of wear resistance, high temperature resistance, corrosion resistance and good anti-scratch performance. It has a long service life, stable sealing performance and can effectively prevent medium leakage.
Easy to open and close: It adopts a wedge-shaped elastic gate structure. For medium and large diameters, rolling bearings are installed. The opening and closing torque is small, and the operation is flexible. It can greatly reduce the labor intensity of operators and improve work efficiency.
Wide application range: It is suitable for a variety of cryogenic media, such as liquefied natural gas, liquid nitrogen, liquid oxygen, etc. It is widely used in the cryogenic pipeline systems of the petroleum, chemical, natural gas, liquefied gas and other industries for cutting off or connecting the pipeline media.
Compact structure: The overall structural design is compact and reasonable, with an attractive appearance, taking up little space, convenient for installation and maintenance, and at the same time ensuring the rigidity and stability of the valve.
Strong compatibility: It complies with international standards such as API 600, ANSI B16.10 and ANSI B16.34, and can be used in conjunction with various imported equipment and pipeline systems in the world, having good interchangeability and universality.
Technical Parameters
Nominal diameter: 1/2"~48" (DN15~DN1200)
Pressure rating: 150LB~2500LB (PN20~PN420)
Applicable temperature range: -196℃~120℃
Applicable media: Cryogenic media such as liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, cryogenic ethylene, etc.
Valve body material: Cryogenic carbon steel
Sealing surface material: Stellite cobalt-based hard alloy overlaid by welding
Valve stem material: Alloy steel subjected to quenching and tempering and surface nitriding treatment, with good corrosion resistance and anti-scratch properties
Connection method: Flange connection, conforming to the ANSI B16.5 flange standard
Operation mode: Multiple operation modes such as manual, gear transmission, electric and pneumatic are available for selection.
Application Fields
This valve is mainly used in the cryogenic pipeline systems of the petroleum, chemical, natural gas, liquefied gas and other industries for cutting off or connecting the pipeline media. It can also be used for the inlet and outlet control of equipment such as cryogenic storage tanks and cryogenic heat exchangers. Its excellent cryogenic performance and reliable sealing performance enable it to operate stably in extremely low-temperature environments, ensuring the safety and reliability of the system.
Quality and Inspection
Design and manufacturing: The design and manufacturing are carried out in strict accordance with the API 600 standard to ensure the overall quality and performance of the valve.
Inspection and testing: Strict inspections and tests are carried out in accordance with the API 598 standard, including shell pressure test, sealing test, cryogenic performance test, etc., to ensure that each valve meets the relevant standard requirements before leaving the factory.
Quality assurance: The quality is strictly controlled throughout the whole process from the procurement of raw materials to the delivery of finished products. A perfect quality management system is established to provide users with high-quality and high-performance products.
