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 for dependable on/off control of various media such as water, air, oil, gas, and fuel. The UD sub-series offers standard port sizes ranging from G3/8" to G1‑1/4", while the UW sub-series is designed for larger ports, spanning from G1‑1/4" to G2", to support high-flow applications.
Built with versatility in mind, this valve utilizes a direct-acting diaphragm mechanism that permits operation starting at zero pressure (0 bar). This design eliminates the necessity for a minimum differential pressure, ensuring instant responsiveness and consistent performance even in low-pressure environments or gravity-fed systems.
The 2W Series is available in both Normally Closed (NC) and Normally Open (NO) configurations, allowing customization to suit specific system demands. The valve body is manufactured from forged brass in the 2W variant or stainless steel in the 2S variant. It also offers multiple seal options, including standard NBR, EPDM, and FKM (Viton), to handle a wide range of media types and temperature conditions.
Standard operating voltages include DC24V, AC110V, AC220V, and AC380V. Additionally, custom voltage options can be provided upon request to further align with particular application requirements.
Features:
Zero Pressure Start
The direct-acting design allows the system to operate reliably starting from 0 bar pressure. This feature makes it particularly suitable for low-pressure and gravity-fed systems, ensuring seamless performance even under minimal pressure conditions.
High Flow Capacity
Our product range includes orifice sizes from 16 mm up to 50 mm in the UW series. With Cv values spanning from 4.8 to 48, these valves guarantee efficient flow control and excellent system performance across various applications.
Durable Construction
Constructed from either forged brass (2W) or precision-cast stainless steel (2S), these components offer outstanding corrosion resistance and enhanced durability, ensuring a long operational lifespan in demanding environments.
Multiple Seal Options
Standard seals made of NBR support operation within temperatures ranging from -5°C to +80°C. For applications requiring higher temperature resistance or specific chemical compatibility, EPDM and FKM (Viton) seal variants are also available.
Flexible Configurations
The product is offered in both Normally Closed (NC) and Normally Open (NO) configurations to meet diverse operational requirements and facilitate easy integration into existing systems.
Versatile Voltage Options
These valves support a wide array of AC and DC voltages, including DC24V, AC110V, AC220V, and AC380V, with a tolerance of ±10%, providing flexible power compatibility for various setups.
