Valves for Oil & Gas Pipelines

Oil And Gas Valves:

1. Petroleum Refining
For petroleum refining—characterized by high temperatures (e.g., 300-400°C in atmospheric/vacuum distillation towers), complex media (heavy oil, corrosive gases, coking-prone fluids), and continuous operation requirements—HEARKEN Flow provides customized valve solutions. These include high-temperature gate valves for atmospheric/vacuum distillation towers (withstanding up to 400°C), coke-resistant globe valves for catalytic cracking units, and safety valves for pressure relief in reforming systems. Paired with reliable pneumatic/electric actuators featuring anti-seizure design and suitability for harsh working conditions, the solutions can endure the rigorous environments throughout the entire process of extraction, refining, and transportation. They effectively prevent leakage, reduce unplanned downtime, and ensure safe and continuous production.
2. Oil and Gas Production
Focusing on the high-pressure, flammable, and corrosive operating conditions in oil and gas production, HEARKEN Flow offers application-specific customized valves for critical scenarios:
High-pressure trunnion-mounted ball valves resistant to H₂S for wellheads and gathering systems (withstanding up to 10,000 PSI);
Anti-surge control valves for centrifugal compressor discharge;
Fast-response pneumatic butterfly valves for fire water lines (achieving full open/close in < 5 seconds);
Check valves for flowlines and oil/gas separation systems to prevent fluid backflow.
Combined with SIL-compliant actuator systems, the solutions deliver robust flow control and intrinsic safety, reducing hazards in high-risk environments.
3. Petrochemicals
Addressing the needs for precise flow control and zero leakage in petrochemical processes involving low-temperature media (e.g., ethylene at -55~100°C), high-pressure fluids (e.g., propylene), and corrosive gases, HEARKEN Flow’s specialized valves and actuators serve as core components:
Cryogenic ball valves for ethylene plants (preventing cold loss and ensuring tightness);
High-precision pneumatic control valves for propylene processing (with ±0.5% accuracy);
Alloy globe valves for reboiler systems (withstanding cyclic thermal stress and resisting acid/alkali corrosion);
Multi-way valves for gas distribution to avoid cross-contamination.The actuator-valve systems comply with the fugitive emissions standards of API 624/ISO 15848-1, reducing environmental impact while enhancing the output of high-quality petrochemical products.
