Product Description:
UNID UW Series Solenoid Valve
The UNID UW series solenoid valve is designed with a pilot diaphragm-driven mechanism and features a normally closed configuration. This means the valve remains closed when not energized and opens once power is supplied. Such a design ensures reliable operation and safety in various applications.
One of the key advantages of this series is its capability to function directly under zero pressure differential, which broadens its usability across numerous systems. The valve body construction varies based on size: forged brass is used for valves sized 3/8" to 1", while cast bronze is employed for larger sizes ranging from 1¼" to 2". These materials offer outstanding resistance to corrosion, enhancing the valve’s durability.
For sealing, the UW series comes standard with NBR seals rated up to 80°C. Additionally, optional seals made from Viton or Silicon are available to accommodate higher fluid temperatures of up to 130°C. This flexibility allows the valve to adapt to various fluid temperature requirements.
The valve features standard threaded connection options including BSPT, NPT, and BSP threads, ensuring compatibility with international piping standards. Coil voltages typically include 110VAC, 220VAC, and 24VDC, but custom voltages can be provided upon request to meet specific operational needs.
Due to its robust features and versatility, the UNID UW series solenoid valve is commonly utilized in a wide range of industries such as water treatment, industrial automation, heating, ventilation, air conditioning (HVAC), and the transfer of light oils.
Features:
The pilot diaphragm structure is specially designed to provide sensitive opening and closing actions while ensuring excellent anti-clogging performance. This design enhances reliability and responsiveness in various applications.
Featuring zero pressure differential operation, this system requires no minimum pressure to function effectively. This allows for smooth operation under a wide range of conditions without the need for additional pressure.
Customers can choose between dual body material options to best suit their needs: forged brass for sizes ranging from 3/8" to 1", and cast bronze for sizes from 1¼" to 2". These material choices provide versatility and durability across different environments.
The product supports multiple seal materials as well. The standard option is NBR, rated for temperatures up to 80°C, while optional Viton or Silicon seals are available for higher temperature applications up to 130°C, making it suitable for handling a variety of fluids.
Compatible with multiple media types such as water, air, and light oil, this device offers a broad operating pressure differential range. For detailed specifications, please refer to the technical data sheet.
Designed with various port sizes from 3/8" to 2" and Cv values ranging from 2.4 to 48, the product meets diverse flow requirements. This broad range ensures adaptability across many different use cases.
It supports a maximum operating pressure differential of up to 7 kgf/cm² for air, and up to 5 kgf/cm² for water and light oil. This robust pressure handling capability ensures dependable performance under demanding conditions.
Installation is made convenient by threaded connections available in BSPT, NPT, and BSP standards, providing flexible options to match existing systems.
The coil voltage tolerance is designed for stability, allowing for AC variations of ±10% and DC variations of ±1%, which helps maintain consistent operation even under fluctuating power supplies.
Finally, the compact and lightweight design facilitates easy integration into existing setups without adding significant bulk or complexity.

Packing and Shipping:
Product Packaging and Shipping for Pneumatic Solenoid Valve
Each pneumatic solenoid valve is carefully packaged to ensure safe delivery and protection against damage during transit. The valve is first wrapped in anti-static bubble wrap to prevent any electrostatic discharge and physical impact. It is then placed in a sturdy, custom-fitted cardboard box with additional cushioning materials such as foam inserts or packing peanuts to secure the product firmly in place.
The outer packaging is clearly labeled with product information, handling instructions, and shipping details to ensure proper identification and careful handling throughout the shipping process. For bulk orders, multiple units are securely packed in larger cartons with dividers to avoid contact between individual valves.
We offer various shipping options including standard, expedited, and freight services to meet customer requirements. All shipments include tracking information and are dispatched promptly from our warehouse to ensure timely delivery.
Special packaging requests or custom branding can be accommodated upon request to suit specific customer needs.
