High physical tolerance components designed to ensure reliable circuit isolation during power surges or localized utility overloads.
The Commonwealth of the Bahamas operates in one of the most demanding environmental climates globally. Characterized by high humidity, constant marine salt mist spray, and sub-tropical temperatures, industrial equipment is highly susceptible to galvanic corrosion and mechanical binding. Furthermore, the archipelago relies heavily on autonomous infrastructural units, notably decentralized seawater reverse osmosis (SWRO) plants, marine auxiliary machinery, offshore fueling systems, and resort HVAC management installations.
For fluid systems, the solenoid valve core acts as the physical actuator controlling pilot-operated assemblies. A single core failure—due to magnetic degradation, corrosion binding, or seal disintegration—can shutter an entire desalination facility or cargo vessel operation. Thus, Jifeilong’s advanced metallurgical engineering provides specific, redundant safeguards to guarantee long-term system life cycle reliability.

The Bahamas relies heavily on reverse osmosis technology to convert seawater into clean drinking water. Solenoid valves play a crucial role in managing chemical dosing (including chlorine, bisulfite, and anti-scalants), flushing membranes, and shifting flow direction.
A key issue in these operations is magnetic hysteresis. When a valve stays energized for long periods, residual magnetic forces can prevent the core from releasing when power is cut. Our DT4C soft magnetic cores undergo deep hydrogen annealing to eliminate internal stress, ensuring clean shut-offs and preventing water hammer damage or chemical overdosing.
Utility providers in Nassau are working to modernize electrical distribution grids to better handle hurricane stresses and incorporate solar microgrids. This work requires highly reliable low-voltage switchgears and Molded Case Circuit Breakers (MCCBs).
Jifeilong supplies high-ductility copper rivets and precision-ground shafts that maintain strict structural clearance inside trip mechanisms. By utilizing specialized surface treatments like nickel-phosphorus plating, our hardware resists thermal expansion and galvanic corrosion, keeping circuit breakers responsive through years of service.
Formerly Yueqing Feilong Instrument Factory, established in September 1999, we operate from the Oujiang Port Industrial District in Wenzhou City.
Over more than two decades, we have evolved from a local component maker into a highly automated, export-oriented manufacturing enterprise. Our facility integrates machining, grinding, cold heading, and precision stamping. We produce custom shafts, electrical switch hardware, EV terminal pins, and solenoid valve cores.
Our products serve critical roles across the home appliance, fluid control, electronics, automotive, and water filtration sectors. Guided by our core principle—"Seeking truth from facts, quality first"—we ensure every manufacturing stage, from raw material inspection to final packaging, is fully documented under our ISO9001 certified quality management system.
"Our vision is to build an international supply chain for precision hardware. By using automated production and advanced quality control, we deliver reliable products directly from our factory to infrastructure projects throughout the Caribbean."
