In fields such as energy and chemical engineering, and oil and gas transportation, high-pressure fluid control has always been a core challenge. As an industry leader, J-VALVES, relying on the outstanding performance of its Class 900 high-pressure pneumatic welded ball valves, provides global industrial users with safe and efficient solutions.
I. High-Pressure Performance
J-VALVES HIGH-PRESSURE PNEUMATIC WELDED BALL VALVES strictly follow the ASME B16.34 and API 6D standards. The pressure ratings cover from 150LB to 2500LB and can withstand extreme working conditions of up to 42.0MPa (2500LB). Its FULLY WELDED VALVE body design adopts the narrow-gap submerged arc welding process, and the weld strength far exceeds the industry standards, ensuring long-term stable operation under high-pressure scenarios such as long-distance natural gas pipelines. Through the API 598 sealing test, the valve achieves zero leakage under the pressure of 42.0MPa (2500LB), far surpassing the reliability of similar products.
II. Materials and Processes
Top-quality materials: The valve body is made of corrosion-resistant alloys such as F316 stainless steel, duplex steel (2205/2507), and C95800 nickel-aluminum bronze. It has passed the NACE MR0175 certification and can resist corrosive media such as hydrogen sulfide, strong acids, and strong alkalis.
Precision manufacturing: By applying 3D simulation welding stress analysis technology and combining it with ultrasonic impact treatment for stress relief, it ensures that the valve body has no deformation or cracks within the temperature range from -46°C to 450°C.
Fireproof design: It complies with the API 607 and ISO 10497 standards. Even under fire conditions, the graphite gasket and fireproof lip structure can still maintain the seal and avoid catastrophic leakage.
III. Intelligent Drive
The pneumatic actuator of J-VALVES adopts a double-acting piston design, with a response time of less than 0.5 seconds. It can achieve safe operation with an explosion-proof grade of ATEX II 2G Ex db IIC T4 in flammable and explosive environments. By integrating an intelligent positioner, it supports remote adjustment of 4-20mA signals. In cooperation with the travel switch and valve position feedback device, it ensures that the control accuracy of the valve opening reaches ±1%.
IV. Stringent Testing
Full-pressure test: Each valve passes the shell strength test at 1.5 times the nominal pressure and the sealing test at 1.1 times the nominal pressure to ensure a 100% pass rate for products leaving the factory.
Life verification: It has completed 100,000 opening and closing cycle tests under simulated working conditions, and the sealing performance has no attenuation, far exceeding the industry standard of 30,000 times.
Certification endorsement: It holds international certifications such as API 6D, ISO 9001, CE/PED, and has passed the SIL3 functional safety certification, making it suitable for high-risk industrial scenarios.
V. Industrial Applications
Oil and gas development: In the FPSO project in Brazil, J-VALVES 2500LB BALL VALVES have been successfully applied to the crude oil processing system with a capacity of 180,000 barrels per day, achieving trouble-free operation for five consecutive years.
Coal chemical industry: The hydrogenation valves customized for the direct coal liquefaction project of Shenhua Group have been operating stably for seven years under a pressure of 4,500 pounds and a high temperature of 538°C, with a cost only 50% of that of imported products.
New energy: In the LNG receiving station, under the ultra-low temperature environment of -196°C, the valve still maintains zero leakage, ensuring the safe transportation of liquid natural gas.
VI. Service Commitment
J-VALVES provides 7×24-hour technical support. Equipped with a professional after-sales team, it can arrive at any site around the world within 48 hours. Through the remote diagnosis system, it can monitor the valve status in real time, and predictive maintenance reduces the risk of shutdown. All products are provided with a 5-year quality guarantee, and the lifespan of the core components can reach more than 10 years.
Choosing J-VALVES means choosing a safe, efficient, and sustainable industrial future. We take the 2500LB high-pressure pneumatic welded ball valve as a benchmark to help customers break through limits under extreme working conditions and achieve excellence!
