UW-25 Forged Brass Body Air Valve UNID 1" Orifice 25 mm Water Valve

Product Description:

The UNID UW series solenoid valve utilizes a pilot diaphragm-driven mechanism and is designed as a normally closed valve. This means the valve remains closed when de-energized and opens only when energized, ensuring reliable control in various applications.

One of the notable features of this series is its ability to operate directly under zero pressure differential, which greatly enhances its versatility and adaptability across different systems. Depending on the valve size, the body is made from different materials to ensure durability and performance: forged brass is used for sizes ranging from 3/8" to 1", while cast bronze is employed for sizes from 1¼" up to 2". Both materials provide excellent resistance to corrosion.

The valve comes standard with NBR seals rated for temperatures up to 80°C. For applications requiring higher temperature tolerance, optional seals made of Viton or Silicon, which can endure temperatures up to 130°C, are also available. To accommodate various piping standards worldwide, the valve supports several threaded connection types including BSPT, NPT, and BSP.

Standard coil voltages offered for the UW series include 110VAC, 220VAC, and 24VDC. However, special voltage requirements can be fulfilled upon request to meet specific customer needs. Due to its robust design and flexible features, the UW series solenoid valve is widely applied in fields such as water treatment, industrial automation, HVAC systems, and light oil transfer.

Features:

The pilot diaphragm valve is designed to provide sensitive opening and closing actions while ensuring excellent anti-clogging performance. Its structure allows for reliable operation in various demanding conditions.

This valve operates with zero pressure differential, meaning it requires no minimum pressure to function effectively. This feature guarantees smooth and precise control across a wide range of applications.

To accommodate different installation needs, the valve offers dual body material options. Forged brass is available for sizes from 3/8 inch to 1 inch, while cast bronze is used for larger sizes ranging from 1¼ inches to 2 inches.

The standard seal material is NBR, suitable for temperatures up to 80°C. For higher temperature requirements up to 130°C, optional Viton or Silicon seals can be selected. This range ensures compatibility with various fluid temperatures.

This valve supports multiple media types including water, air, and light oil. It functions efficiently over a wide operating pressure differential range (refer to technical data for specifics). The maximum allowable pressure differential is up to 7 kgf/cm² for air and up to 5 kgf/cm² for water and light oil.

Available in multiple port sizes from 3/8 inch to 2 inches, with flow coefficients (Cv) ranging from 2.4 to 48 to meet diverse flow requirements. Threaded connections include BSPT, NPT, and BSP standards, providing flexible installation options. The coil voltage tolerances are ±10% for AC and ±1% for DC, ensuring stable and reliable operation.

The valve features a compact and lightweight design, making it easy to integrate into existing systems without adding significant bulk or weight.
