As a trusted manufacturer since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in precision-engineered flow control solutions. Our Low-Torque JIS F7480 Marine Pneumatic Butterfly Valve is specifically designed for demanding fuel oil transfer applications in marine environments. Engineered with triple eccentricity and optimized sealing geometry, this valve ensures leak-tight performance while requiring minimal actuation force – reducing energy consumption and operational costs.
This valve meets rigorous JIS F7480 standards for marine valves, offering exceptional corrosion resistance through its stainless steel construction. The pneumatic actuation system provides precise flow control for viscous fuels like IFO 380 and MDO, making it ideal for bunkering operations, tank farms, and shipboard piping systems where reliability is non-negotiable.
Core Technical Specifications:
| Design Standard | JIS F7480 Marine Valve Standard |
| Pressure Class | 10K/16K (PN16/PN25) |
| Temperature Range | -20°C to 150°C |
| Seat Material | Reinforced PTFE with Stainless Steel Insert |
| Actuator Type | Double-Acting Pneumatic (SCOTCH YOKE) |
| Torque Requirement | ≤30% of Standard Butterfly Valves |
Operational Advantages:
- Reduced actuator size requirements due to low torque design
- Bubble-tight shutoff for high-viscosity fuels
- Fire-safe construction with secondary metal sealing
- Maintenance-free operation with self-lubricating bearings
- Corrosion-resistant SS316 components for seawater exposure
- Quarter-turn operation enables rapid emergency shutdown
Backed by ISO9001 certification and annual exports exceeding US$1 million to global marine markets, our valves are trusted across five continents. With shipment flexibility through Shanghai, Guangzhou, Hong Kong, and Beijing ports, we ensure timely delivery to North American shipyards, European bunkering terminals, and Asian port authorities alike. The reduced lifecycle cost – combining energy-efficient operation with minimal maintenance – delivers ROI within 18 months for high-cycle fuel transfer applications.
Frequently Asked Questions:
-
Q: Is this valve suitable for heavy fuel oil (HFO) service?
A: Yes, the triple eccentric design prevents viscous media buildup, while PTFE-stainless composite seats handle HFO's abrasive particles. -
Q: What certifications accompany this product?
A: All valves include material traceability and ISO9001 manufacturing certification. Optional NACE MR0175 compliance is available. -
Q: Why emphasize low torque in pneumatic valves?
A: Reduced torque allows smaller, more economical actuators and lowers compressed air consumption by 25-40% versus standard designs. -
Q: Can I get customized flange drilling patterns?
A: Yes, we offer JIS, ANSI, or DIN flange configurations according to your piping specifications. -
Q: What maintenance intervals are recommended?
A: Our valves require only annual visual inspection and 5-year comprehensive maintenance under normal operating conditions.
