Product Description:
The 2W Series, which includes the 2W UD and 2W UW sub-series, represents a line of high-performance, direct-acting 2/2-way solenoid valves. These valves are specifically designed to provide reliable on/off control for various media such as water, air, oil, gas, and fuel. The UD series accommodates standard port sizes ranging from G3/8" to G1‑1/4", while the UW series is intended for high-flow applications with larger port sizes from G1‑1/4" up to G2".
Built with versatility in mind, the valves utilize a direct-acting diaphragm mechanism, enabling operation starting at zero pressure (0 bar). This design eliminates the necessity for a minimum differential pressure, ensuring quick response times and dependable performance, even in systems with low pressure or those that rely on gravity feed.
The 2W Series is available in both Normally Closed (NC) and Normally Open (NO) variants, allowing customization to suit specific application needs. The valve bodies come in forged brass for the 2W model and stainless steel for the 2S model. Additionally, a variety of seal materials including NBR (standard), EPDM, and FKM (Viton) are offered to handle different media types and temperature conditions.
Regarding power supply, the valves support standard voltages such as DC24V, AC110V, AC220V, and AC380V. Custom voltage options can also be provided upon request to meet unique operational requirements.
