Product Description:
The 2W Series, which includes the 2W UD and 2W UW sub-series, is a high-performance, direct-acting 2/2-way solenoid valve designed to provide reliable on/off control for various fluids such as water, air, oil, gas, and fuel. The UD sub-series offers standard port sizes ranging from G3/8" to G1‑1/4", whereas the UW sub-series caters to larger port sizes from G1‑1/4" up to G2", making it ideal for high-flow applications.
Designed with versatility in mind, this valve incorporates a direct-acting diaphragm mechanism that enables it to operate efficiently from zero pressure (0 bar). This feature eliminates the necessity for a minimum differential pressure, ensuring the valve responds instantly and performs consistently 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) configurations, allowing customization based on specific system needs. The valve body is manufactured from forged brass (2W) or stainless steel (2S), offering durability and compatibility with different environments. Additionally, seal materials such as NBR (standard), EPDM, and FKM (Viton) are offered to handle a variety of media types and temperature ranges. The valves support standard voltages including DC24V, AC110V, AC220V, and AC380V, with custom voltage options available upon request.
