2S series direct-acting type Stainless steel solenoid valve with excellent resistance performance

The SENYA 2S Series stainless steel solenoid valves are engineered for extreme chemical resistance, utilizing AISI 304/316L stainless steel construction with electropolished interiors to withstand aggressive media including acids (up to 10% sulfuric/hydrochloric), alkalis, ozone (200ppm), and chlorine gases.

Featuring our seal technology with optional FKM or PTFE materials, these valves deliver 300% longer service life than standard models in oxidative environments. The ultra-responsive design achieves 50ms actuation (DN15 size) with ±1ms repeatability, powered by energy-efficient copper-clad aluminum coils rated for over 1 million cycles. Available in IP65/IP67 protection with optional coil explosive-proof, the series includes sizes from 1/8″ to 2″ with NPT/BSPP connections, supporting pressures 0-10 bar and temperatures to 180℃ (high-temp version).

Rigorously tested with 2,000+ hour salt spray (ASTM B117), 500,000 cycle endurance, and real-world ozone exposure validation, these valves are ideal for ozone generators (0-200g/m³), chemical dosing (pH 1-14), semiconductor processing, and pharmaceutical applications. Our one-year guaranteed performance reduces maintenance costs by 40% and downtime by 60%, backed by 24/7 technical support and custom engineering for specific media, pressure, and temperature requirements – contact our team for a tailored solution analysis and proposal.
