0 to 0.5 MPa water valve normally closed and normally open variants developed

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. It is suitable for various media such as water, air, oil, gas, and fuel. The UD series accommodates standard port sizes ranging from G3/8" to G1‑1/4", whereas the UW series is designed for larger ports, spanning from G1‑1/4" to G2" to handle high-flow requirements.

Built with versatility in mind, this valve employs a direct-acting diaphragm mechanism that enables operation starting from zero pressure (0 bar). This design eliminates the necessity for minimum differential pressure, ensuring prompt response and reliable operation even in low-pressure environments or gravity-fed systems.

The 2W Series is offered in both Normally Closed (NC) and Normally Open (NO) variants, allowing customization to fulfill diverse system demands. The valve bodies are available in forged brass for the 2W model or stainless steel for the 2S model. Additionally, sealing materials include NBR as the standard option, with alternatives such as EPDM and FKM (Viton) available to cater to different media types and temperature conditions.

Standard voltage options supported include DC24V, AC110V, AC220V, and AC380V, with tailor-made voltage specifications available upon request. This range of configurations makes the 2W Series a flexible and reliable choice for a wide array of applications.

Features:

The product features a zero pressure start capability, thanks to its direct-acting design. This allows for dependable operation starting from 0 bar, making it ideal for low-pressure environments and gravity-fed systems.

It offers high flow capacity with orifice sizes ranging from 16 mm to 50 mm in the UW series. The Cv values vary between 4.8 and 48, ensuring optimal efficiency and performance across different system requirements.

Constructed from high-quality materials, the product is available in forged brass (2W) and precision-cast stainless steel (2S) variants. Both options provide excellent resistance to corrosion and contribute to a long service life.

Multiple sealing options are provided to meet various operational demands. The standard seals are made of NBR, suitable for temperatures from -5°C to +80°C. Additionally, EPDM and FKM (Viton) seals are available for applications requiring higher temperature resistance or enhanced chemical compatibility.

Users can choose between Normally Closed (NC) and Normally Open (NO) configurations, offering flexibility to suit different control system needs.

The device supports a broad range of voltage options, including DC24V, AC110V, AC220V, and AC380V, all with a tolerance of ±10%, making it versatile for various electrical environments.

It accommodates a wide range of port sizes, from G3/8" up to G2" threaded connections, enabling easy integration with diverse piping systems.

This product is compatible with multiple media types such as air, water, oil with viscosity up to 20 CST, as well as gas and fuel applications.

Operational temperature ranges from -5°C to +80°C, ensuring reliable performance under various environmental conditions.

Designed to be compact yet robust, the product’s small footprint and durable construction facilitate straightforward installation and long-lasting use.

For specialized requirements, custom voltages and specifications can be arranged directly with the factory, offering tailored solutions to meet unique application needs.
