The RSSM series direct-acting solenoid valve is an industrial-grade electromagnetically controlled valve deeply customized for high-pressure, micro-flow precision fluid piping control. This series features refined specifications covering nominal diameters from DN6 to DN8, supporting both universal G threads and high-tightness NPT thread connections. Utilizing a pure direct-acting drive architecture completely independent of pipeline medium pressure, it achieves instantaneous and agile opening and closing under zero differential pressure conditions. The valve body is available in premium brass or industrial stainless steel SS316, making it widely adaptable for pipeline shut-off and automated control of water, neutral liquids, and various gases.

Feature
Zero Differential Pressure Startup: Equipped with a direct-acting electromagnetic structure, the opening and closing rely entirely on the electromagnetic force and spring return, operating flawlessly at 0 bar pressure drop.
Medium-to-High Pressure Durability: Rated for nominal pressures up to 20 bar, the internal structure is precision-engineered for excellent high-pressure resistance and zero-leakage sealing.
Premium Material Guarantee: Offers highly corrosion-resistant SS316 stainless steel and wear-resistant brass bodies to meet diverse media requirements, ranging from standard water lines to mildly corrosive fluids.
Compact and Efficient Design: Features a small flow passage volume, short response time, and high switching frequency, making it easy to integrate into compact industrial control cabinets or fluid equipment with limited space.
