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 expertly designed to provide reliable on/off control for a variety of fluids such as water, air, oil, gas, and fuel. The UD sub-series caters to standard port sizes ranging from G3/8" up to G1‑1/4", while the UW sub-series is intended for larger ports ranging from G1‑1/4" to G2", making it suitable for high-flow applications.
This valve is engineered with versatility in mind, featuring a direct-acting diaphragm structure that enables operation starting from zero pressure (0 bar). This design removes the necessity for a minimum differential pressure, ensuring the valve responds immediately and performs reliably even in low-pressure or gravity-fed systems.
The 2W Series is available in both Normally Closed (NC) and Normally Open (NO) configurations, allowing customization according to specific system needs. The valve body can be constructed from forged brass (2W) or stainless steel (2S), while various seal materials are offered, including NBR as the standard, along with EPDM and FKM (Viton), to handle different media types and temperature ranges.
Additionally, the series supports standard voltage options such as DC24V, AC110V, AC220V, and AC380V. Custom voltages can also be provided upon request to fit unique operational requirements.
Features:
Zero Pressure Start
The direct-acting design allows the device to operate reliably starting from 0 bar pressure. This feature makes it ideal for use in low-pressure environments and gravity-fed systems.
High Flow Capacity
The UW series offers orifice sizes ranging from 16 mm to 50 mm, with Cv values between 4.8 and 48. This ensures that the system maintains efficient performance across a variety of flow requirements.
Durable Construction
Constructed using forged brass (2W) or precision-cast stainless steel (2S), these units provide excellent resistance to corrosion and offer long-lasting durability in demanding environments.
Multiple Seal Options
Standard models come equipped with NBR seals that operate effectively within a temperature range from -5°C to +80°C. For applications demanding higher temperature resistance or chemical compatibility, EPDM and FKM (Viton) seals are also available.
Flexible Configurations
The product is offered in both Normally Closed (NC) and Normally Open (NO) configurations, allowing it to meet diverse operational requirements.
