The RST Series Direct Acting Solenoid Valve is an electromagnetically driven control valve deeply customized for high-precision fluid pipeline control and medium-to-high pressure universal automated equipment. Featuring a delicate nominal diameter range of DN6 to DN8, this series boasts a compact and streamlined profile that greatly optimizes space efficiency. It fully supports high-precision G thread and NPT thread standard connections, ensuring effortless field assembly and seamless interchangeability across domestic and international piping networks. Utilizing a classic direct-acting internal configuration, the valve requires zero differential operating pressure to open or close, delivering exceptional actuation sensitivity, minimal flow resistance, and ultra-fast response times throughout a broad pressure range from 0 to 20 bar. Engineered with a premium high-density forged brass body, it exhibits dense structural properties with superior pressure and fatigue resistance, offering comprehensive compatibility with media such as water, liquid fluids, air, and neutral gases. It serves as the premier and ideal control component for modern integrated fluid automation control systems.

Compact Footprint & Multi-Thread Standards: Specially tailored for small DN6~8 bore pipelines, the entire structure is engineered for maximum compactness to save installation space. Full compatibility with international G and NPT thread standards permits flawless mating with various global industrial automation networks.

Zero Differential Startup & High-Pressure Sensitivity: Benefiting from a pure mechanical direct-acting design, the valve platen is actuated directly by electromagnetic force without reliance on pilot orifices or flexible diaphragms. It yields a clean, snappy, and instantaneous open/close stroke under zero pressure drop (0 bar) up to a high operating threshold of 20 bar.

Robust Forged Brass Body with High Overload Resistance: The valve body is precision-machined from high-grade forged brass, creating a dense internal matrix free of blowholes. It offers exceptional pressure containment, wear resistance, and anti-rust capability, extending service life during high-frequency cycles.

All-Weather Temperature Range & Ageing Resilience: With an operational temperature scope of -10 to 80 ℃, the core internal seals utilize premium elastomeric formulations. These seals resist hardening and cracking even under high industrial temperatures or freezing outdoor climates, securing zero-leakage sealing integrity over an extended lifecycle.
