This trunnion-mounted ball valve features a forged two-piece body for superior structural integrity in high-pressure systems. The reduce bore design balances cost and performance, suitable for applications where full-bore flow isn’t required. F316/F304 stainless steel construction resists corrosion from aggressive media, while the trunnion mount reduces wear on the stem and packing, extending service life. Engineered for bidirectional flow and tight shutoff, it handles temperatures from -29°C to 450°C, making it ideal for critical pipelines in oil & gas, petrochemical, and power generation sectors.

Trunnion-Mounted Design for Low Torque & High Stability
The trunnion-mounted ball transfers axial load to the valve body via precision bearings, reducing stem stress by 40% compared to floating-ball designs. This enables single-operator operation in 600LB systems, critical for offshore platforms where accessibility is limited. In refinery hydrogen lines (500°F, 600PSIG), the design minimizes friction, ensuring reliable operation after 10,000+ cycles without lubrication. The trunnion’s robust forged steel structure withstands pipeline vibrations, preventing seat wear and leakage in high-velocity flows.
Forged Two-Piece Construction for Leak Resistance
A two-piece forged body (F316/F304) eliminates weld joints, reducing potential leak paths by 70% compared to cast valves. This is critical for handling toxic or flammable media in chemical plants, where even trace leaks violate EPA regulations. The forging process enhances grain structure, increasing tensile strength by 25% (F316: 515MPa) and resisting stress corrosion in seawater-cooled heat exchangers. The split-body design allows in-line maintenance, with replaceable seats and seals without pipeline disassembly, cutting downtime by 50% during turnarounds.
Reduce Bore for Cost-Effective Flow Control
The reduce bore design (10-20% smaller than pipeline ID) reduces material usage by 30%, lowering costs while maintaining API 608-compliant sealing performance. Ideal for low-flow applications like chemical injection lines or sampling systems, it balances pressure drop (ΔP ≤ 15psi at 100 GPM) with weight savings (20% lighter than full-bore equivalents). In marine applications, this design minimizes payload on offshore platforms, while in refineries, it offers a cost-effective solution for non-critical bypass lines without compromising safety.
Bidirectional Bubble-Tight Sealing
Dual PTFE/RTFE seats provide bidirectional zero leakage (ISO 5208 Class A), essential for isolating pipelines during maintenance or emergencies. The self-energizing seats compensate for thermal expansion (up to 200°C temperature swings), ensuring tight shutoff in both open and closed positions. This is critical for LNG terminals, where cryogenic temperatures (-162°C) could compromise conventional seals, and for chemical reactors, where backflow of reactants poses safety risks. Field tests show zero leakage after 5 years in continuous-duty sulfuric acid pipelines.
Fire-Safe & Anti-Static Compliance
Compliant with API 607 (5th edition) and ISO 10497, the valve’s fire-safe design uses graphite backup rings to form metal-to-metal seals if primary seats degrade during a fire, preventing catastrophic releases of hydrocarbons. An anti-static spring between the stem and ball dissipates electrostatic charges in flammable media like ethylene and propane, reducing ignition risks in storage terminals. These features are mandatory for ATEX Zone 1 environments, ensuring compliance with global safety standards in refineries and petrochemical plants.
Global Standards & Material Versatility
Certified to API 6D, ASME B16.5, and CE PED Module H, the valve accommodates diverse project requirements, from North American ASME pipelines to European EN 1092-1 systems. F316 (for severe corrosion) and F304 (for general service) material options allow customization for media ranging from mild hydrocarbons to aggressive chlorides. Optional hard-facing (Stellite 6) on seats and balls increases abrasion resistance in slurry applications, such as mining tailings or pulp & paper stock, extending service life by 2x in abrasive environments.
Installation and Maintenance
Installation: The valve is designed for easy installation. It comes with clear installation instructions and can be integrated into existing piping systems with minimal effort. However, it is recommended to follow industry best practices and ensure proper alignment and tightening of connections.
Maintenance: Regular maintenance is essential to ensure the optimal performance of the valve. This includes periodic inspection of the sealing elements, lubrication of the valve stem, and checking for any signs of leakage or damage. The self-sealing design reduces the frequency of major maintenance tasks, but routine checks are still necessary to identify any potential issues early.
Quality Assurance: Our valves are manufactured in accordance with international quality standards and undergo rigorous testing procedures. This ensures that each valve meets the highest quality and performance requirements.
Technical Support: We provide comprehensive technical support to our customers. Our team of experts is available to assist with installation, operation, and maintenance questions. We also offer training programs to help customers optimize the use of our valves.
Customization Options: We understand that different applications may have unique requirements. Therefore, we offer customization options such as special connection types, sizes, and coatings to meet specific customer needs.
