The 231Y / VX3 Series 2-Position 3-Way Solenoid Valve is an industrial-grade control valve specifically engineered and highly customized for high-frequency fluid switching, directional reversing, diverting, and mixing systems. Covering a size spectrum from DN15 to DN30, this series fully complies with high-precision G thread and American NPT thread connection standards, greatly facilitating on-site assembly and seamless integration within diverse international piping networks. Featuring excellent zero-differential pressure starting capability, the valve delivers rapid response times and exceptional directional switching reliability across a wide pressure range from 0 to 12 bar. Available in premium forged brass or high-end SS304 stainless steel body variants, and coupled with a high-temperature structural design capable of enduring up to 120 ℃, it ensures universal compatibility with water, liquids, and gases, making it an ideal directional control component for modern automated fluid circuits.

Feature

Zero-Differential Instantaneous Start: Utilizing optimized internal mechanical linkages, the valve possesses the core technical edge of starting at zero pressure differential. Even in systems with completely absent pipeline pressure or extremely low pressure conditions, it performs crisp, instantaneous open, close, and switching strokes, eliminating operational lag.

Versatile 2-Position 3-Way Reversing: Equipped with three independent ports, it perfectly achieves rapid fluid direction switching, flow diverting (one inlet to two outlets), or flow combining (two inlets to one outlet) based on control system electric signals. The internal channels are hydrodynamically optimized to secure low flow resistance and large volumetric capacity.

Dual Materials & High-Temperature Resistance: Available in high-density forged brass or premium SS304 stainless steel bodies, showcasing a compact profile with immense mechanical pressure strength. Integrated with specialized heat-resistant seals, it handles media temperatures up to 120 ℃, operating stably in hot water, high-temperature gases, and mildly aggressive industrial fluids.

Seamless Thread Standarization: Manufactured strictly according to internationally accepted G parallel pipe thread and American NPT tapered pipe thread standards, ensuring the valve modules seamlessly match domestic and global industrial automation loops and integrated fluid manifolds.

High-Frequency & Extended Service Life: Internal plungers and spring assemblies have undergone rigorous mechanical fatigue life testing. They maintain outstanding physical elasticity and bubble-tight sealing capabilities under continuous high-frequency cycling and high pressure differentials, resisting mechanical jamming or sticking.
