Product Overview

Design Standards and Performance Specifications：

Design Standards: The design of this valve strictly adheres to international authoritative standards, such as the American Society of Mechanical Engineers (ASME) standards, ensuring its universality and reliability worldwide. It also refers to relevant standards in the oil and gas industry to meet the requirements for use in high -pressure and high-risk environments.

Performance Specifications: It has a pressure-bearing capacity of up to 10000psi, enabling it to operate stably in extreme high-pressure environments. The sealing performance is excellent, effectively preventing medium leakage and ensuring the safety of the production process. The valve is flexible to operate, and the manual operating mechanism is designed in line with ergonomic principles, allowing for easy opening, closing, and opening-degree adjustment of the valve even in high-pressure environments.

Product Parameter Characteristics

Material: The main body is made of high-quality stainless steel, such as 316L stainless steel. This material has excellent corrosion resistance and high strength, enabling it to maintain stable performance in harsh chemical environments and under high – pressure conditions.

Pressure Rating: The pressure rating is 10000psi, meeting the requirements for ultra-high-pressure valves in fields such as deep-sea oil extraction and high-pressure chemical industry.

Connection Methods: Multiple connection methods are provided, including threaded connection and flange connection. Threaded connection is suitable for small-diameter pipelines and is convenient for installation. Flange connection is suitable for large – diameter or high – pressure pipelines, offering a firm connection and good sealing performance.

Operation Method: It adopts a manual operation method. Operators can accurately control the valve opening according to actual needs, achieving fine adjustment of fluid flow and pressure.

Manufacturing Process：

Casting Process: The valve body is manufactured using a precision casting process. In the high-temperature molten state, the stainless-steel material is precisely cast. By strictly controlling the casting temperature, speed, and cooling process, the internal structure of the valve body is ensured to be dense and uniform, free from defects such as pores and sand holes, thus guaranteeing the high strength and pressure resistance of the valve body.

Machining: After casting, the valve body undergoes multiple machining processes. High-precision CNC machining equipment is used to finely process key parts such as valve seats and valve cores. The machining accuracy of the valve seat sealing surface can reach the micron level to ensure the high-precision sealing performance of the valve.

Surface Treatment: To further enhance the corrosion resistance and wear resistance of the valve, special surface treatment is carried out on the valve, such as chrome plating. The chrome – plated layer can not only effectively resist the erosion of chemical media but also improve the hardness and smoothness of the valve surface, reducing the wear of internal components by the fluid.

Assembly and Testing: During the assembly process, operations are carried out strictly in accordance with the process requirements to ensure that each component is installed in place and fits precisely. After assembly, a comprehensive performance test is carried out on the valve, including pressure testing, sealing testing, and operation testing. During the pressure test, the valve is placed in an environment with a pressure exceeding the rated pressure to detect whether it can withstand high pressure without deformation or leakage. The sealing test uses specific media to detect the sealing performance of the valve under different pressures. The operation test ensures that the manual operating mechanism of the valve is flexible and reliable.
