Product Description:
The 2W Series, which includes the 2W UD and 2W UW sub-series, represents a high-performance, direct-acting 2/2-way solenoid valve. It is specifically designed to provide reliable on/off control for various media including water, air, oil, gas, and fuel. The UD sub-series accommodates standard port sizes ranging from G3/8" to G1‑1/4", whereas the UW sub-series is intended for larger flow applications with port sizes from G1‑1/4" up to G2".
Built with versatility in mind, these valves utilize a direct-acting diaphragm mechanism that enables operation starting from zero pressure (0 bar). This design feature removes the necessity for a minimum differential pressure, ensuring immediate responsiveness and consistent performance even under low-pressure or gravity-fed conditions.
The 2W Series valves are available in both Normally Closed (NC) and Normally Open (NO) versions, allowing them to be customized according to specific system needs. The valve bodies come in either forged brass (2W) or stainless steel (2S), and a variety of seal materials are offered to suit different media and temperature requirements, including standard NBR, EPDM, and FKM (Viton).
Additionally, these valves support a range of standard operating voltages such as DC24V, AC110V, AC220V, and AC380V. Custom voltage options can also be provided upon request, making the 2W Series a flexible and adaptable choice for a wide array of applications.
