The YSG Series Large-Calibre Pulse Solenoid Valve is a high-efficiency control valve specifically engineered for industrial automation high-flow pipelines, environmental dust collector pulsing, and mass volume fluid transport systems. Breaking through the structural limitations of conventional valves, this series completely covers large-bore specifications including DN65, DN80, DN100, DN125, DN150, and DN200. The entire lineup is integrated with high-strength flanged connections compliant with industrial standards, ensuring robust structural integrity and leakage-free sealing under conditions of high flow rates and massive jet blowing volumes.  Utilizing an advanced DC pulse (Direct Current Pulse) actuation mechanism, the valve radically revolutionizes traditional operations by eliminating the need for continuous power supply to maintain an open state. It only requires a microsecond-level electrical pulse signal from the controller during the instantaneous opening and closing transitions; for the remainder of the time, the valve maintains its state via an internal mechanical and aerodynamic self-locking design. This results in exceptional low power consumption, zero heat generation, and an elongated operational lifespan. Optimally calibrated for low-to-medium pressure systems, the YSG series exhibits millisecond-level responsive triggering and powerful tight shut-off under low operational pressures and differentials ranging from 0.3 to 8 bar. Available in Premium Stainless Steel SS304 (JF Series) and High-Grade Cast Iron (CF Series), the valve bodies accommodate water, industrial liquids, compressed air, and non-aggressive gases. This makes them an ideal core control component for modern environmental filtration, chemical processing, water treatment, and metallurgical industries.

Feature

Expanded Bore & Fluid Dynamics Optimization: Optimized internally for DN65 to DN200 pipelines. The spacious and rounded geometry of the internal flow chamber completely minimizes dead corners and turbulence, lowering the flow resistance coefficient and yielding a flow capacity (Kv value) that far surpasses standard solenoid valves.  

Low Power Consumption & Zero Heat Dispersal: Traditional solenoid valves experience extreme coil heating during prolonged energized opening, often leading to coil burnout. The YSG series leverages pulse control, energizing only at the fraction of a second during switching actions (typically requiring a pulse width of only 30-50 ms). The coil remains completely unenergized for the vast majority of its operation, eliminating thermal buildup and boosting electrical safety.  

Superior Low-Pressure Bootstrap Capability: Addressing the industrial drawback where large-bore valves require massive pressure differentials to open, this series optimizes the area ratio of the diaphragm/disc, smoothly unlocking full-capacity blasting or transport under an ultra-low pressure of just 0.3 bar.  

Application-Specific Material Configurations: The JF Series utilizes SS304 Stainless Steel, providing not only corrosion resistance but also meeting strict hygiene standards for pharmaceutical, food processing, or light-chemical water systems. The CF Series uses heavy-duty Cast Iron, delivering massive mechanical robustness and exceptional cost-efficiency, making it highly suitable for environmental dust bagging networks, industrial circulating water, and agricultural irrigation networks.

All-Weather Wide Thermal Resilience: The valve body and elastomeric seals undergo rigorous thermal cycle testing from -20 ℃ to 65 ℃. The sealing compounds sustain perfect flexibility and cracking resistance at low temperatures, successfully preventing freezing-induced fractures or nocturnal leakage in outdoor installations.
