The full process of design, manufacturing and inspection with strong compatibility is in strict accordance with American standards, such as API 600 (flange gate valve standard), ANSI B16.34 (valve Pressure temperature rating), API 598 (valve inspection and test) and other American standards. The flange size, structural length, and connection method are fully compatible with American equipment, imported oil and gas pipelines, and international engineering projects, and can directly replace similar imported valves without adjusting the pipeline layout.
The high-pressure cutoff seal is reliable and suitable for harsh working conditions. It adopts a wedge-shaped elastic gate or parallel double gate structure, and the sealing surface is tightly fitted, which can compensate for temperature difference deformation and processing deviation. The hard seal leakage level reaches ANSI Class V, and the soft seal can reach Class VI; The high-pressure valve body adopts a thick wall design (with a minimum wall thickness in accordance with ANSI B16.34), which has strong impact resistance and deformation resistance, and can be stably used in high-pressure differential scenarios such as oil and gas wellheads and high-pressure steam pipelines for a long time.
Structural optimization, convenient operation and maintenance. Large caliber valves are equipped with rolling bearings or thrust bearings, significantly reducing opening and closing torque and making manual operation more effortless; The valve stem is designed as a rising stem, and the valve opening can be intuitively determined by the length of the valve stem extension, avoiding misoperation; Some models come with a valve stem anti blowout structure to prevent high-pressure media from blowing out the valve stem and improve operational safety; Vulnerable parts (such as fillers and gaskets) have strong universality, and replacement does not require specialized tools, resulting in low maintenance costs.
Corrosion resistant and wear-resistant, with a long service life. Stellite alloy, tungsten carbide and other hard materials used for sealing surface welding, with a hardness of HRC 55 or above, can resist high-pressure medium erosion and particle wear, and have a service life 2-3 times longer than ordinary gate valves; Stainless steel and alloy Material models are acid and alkali resistant, and can be adapted to corrosive media in the chemical industry (such as nitric acid, acetic acid, oil and gas mixture). They are widely used in petrochemical industry, oil and gas transmission, power, coal chemical industry and other industrial fields.
