Product Description:
The UNID UW series solenoid valve is designed with a pilot diaphragm-driven mechanism and operates as a normally closed valve. This means the valve remains closed when de-energized and opens when energized, providing reliable control in various applications.
This valve series is capable of functioning directly under zero pressure differential, which makes it highly versatile and suitable for a wide range of operating conditions. Its design ensures consistent performance even in low-pressure environments.
The valve bodies are constructed from different materials depending on their size. For sizes ranging from 3/8" to 1", forged brass is used, while cast bronze is selected for sizes between 1¼" and 2". These materials offer excellent resistance to corrosion, enhancing the valve's durability and lifespan.
Standard seals in the UW series are made of NBR, rated for temperatures up to 80°C. However, there are options for Viton or Silicon seals which can withstand higher temperatures up to 130°C, catering to various fluid temperature requirements.
To comply with international piping standards, the valves come with standard threaded connections including BSPT, NPT, and BSP. This makes integration into existing systems straightforward and convenient.
The coil of the UW series solenoid valve supports standard voltages such as 110VAC, 220VAC, and 24VDC. Additionally, special coil voltages can be provided upon request to meet specific customer needs.
Due to its robust design and flexible features, the UW series solenoid valve finds extensive applications in fields such as water treatment, industrial automation, HVAC systems, and light oil transfer applications.
Features:
Pilot Diaphragm Structure for Enhanced Performance
The pilot diaphragm is specially designed to provide sensitive opening and closing capabilities, ensuring precise control. Additionally, it offers excellent anti-clogging performance, making it reliable in various operating conditions.
Zero Pressure Differential Operation
This valve operates without any minimum pressure differential requirement, allowing it to function effectively even at zero pressure difference. This feature expands its usability across a wide range of applications.
Material and Seal Options
The valve body is available in two material options to suit different application needs: forged brass for sizes ranging from 3/8" to 1", and cast bronze for sizes from 1¼" to 2". For sealing, multiple materials are offered including standard NBR, which operates up to 80°C, and optional Viton or Silicon seals capable of handling temperatures up to 130°C for higher temperature fluids.
Wide Media Compatibility and Pressure Range
It is compatible with various media such as water, air, and light oil, and supports a broad operating pressure differential range. For detailed specifications, please refer to the technical data sheet.
Versatile Sizes and Flow Capacities
Available in multiple port sizes from 3/8" up to 2", with Cv values ranging between 2.4 and 48, the valve meets diverse flow requirements. The maximum operating pressure differential is rated at 7 kgf/cm² for air, and up to 5 kgf/cm² for water and light oil.
Flexible Installation and Stable Operation
Threaded connection options include BSPT, NPT, and BSP, providing flexibility during installation. Additionally, the coil voltage tolerance is designed for stability, with ±10% for AC voltage and ±1% for DC voltage.
Compact and Lightweight Design
Featuring a compact and lightweight construction, this valve is easy to integrate into various systems without adding significant bulk or weight.
