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. It is designed to provide reliable on/off control for various fluids such as water, air, oil, gas, and fuel. The UD sub-series covers standard port sizes ranging from G3/8" up to G1‑1/4", while the UW sub-series is intended for larger port sizes from G1‑1/4" to G2", making it ideal for high-flow applications.
This valve is engineered with versatility in mind, featuring a direct-acting diaphragm structure that enables it to operate starting from zero pressure (0 bar). This unique design eliminates the need for a minimum differential pressure, ensuring fast response times and dependable performance even in systems that operate under low pressure or are gravity-fed.
The 2W Series is available in both Normally Closed (NC) and Normally Open (NO) configurations, allowing customization to fit specific system demands. The valve body options include forged brass for the 2W version or stainless steel for the 2S variant. Additionally, various seal materials such as NBR (standard), EPDM, and FKM (Viton) are offered to handle different media and temperature conditions.
Standard electrical voltages supported by these valves include DC24V, AC110V, AC220V, and AC380V. Custom voltage options can also be provided upon request, giving further flexibility to accommodate diverse application requirements.
