Product Description:
The UNID SUW series solenoid valve is designed with a pilot diaphragm-driven mechanism and operates as a normally closed valve. This means it remains closed when de-energized and opens only when power is supplied. Such a design ensures reliable operation in various applications.
The valve body is constructed from investment cast SUS 316 stainless steel (CF8M), known for its excellent corrosion resistance. This makes the valve suitable for use with aggressive media as well as in harsh environmental conditions, enhancing its durability and lifespan.
One notable feature of the SUW series is its ability to function directly under zero pressure differential, allowing for greater versatility across different systems. The standard seals used are made of NBR, which can withstand temperatures up to 80°C. For applications requiring higher temperature resistance, optional seals made from Viton or Silicon, rated up to 130°C, are available.
The valve comes with standard threaded connection options such as BSPT, NPT, and BSP, ensuring compatibility with international piping standards. Regarding power supply, the coils are commonly available in 110VAC, 220VAC, and 24VDC. Additionally, special voltage options can be provided upon request to meet specific needs.
Due to its robust construction and versatile features, the SUW series solenoid valve is widely utilized in a variety of industries, including water treatment, chemical processing, pharmaceutical manufacturing, food processing, and vacuum systems.
Features:
Pilot Diaphragm Structure and Performance
The pilot diaphragm is engineered to provide highly sensitive opening and closing actions while delivering excellent anti-clogging capabilities. This ensures reliable operation even in demanding environments where fluid contamination might be a concern.
Zero Pressure Differential Operation
This device operates effectively without the need for any minimum pressure differential, allowing seamless functionality under zero differential pressure conditions. This makes it versatile for a variety of applications.
Durable Stainless Steel Construction
Constructed from SUS 316 stainless steel (also known as CF8M) using investment casting, the body offers superior resistance to corrosion. This makes the device particularly suitable for handling corrosive fluids and harsh industrial environments.
Seal Material Options
The pilot diaphragm comes with multiple seal materials to accommodate different temperature requirements. The standard seal is made of NBR which supports temperatures up to 80°C. For higher temperature fluids, optional Viton or Silicon seals are available, both rated for up to 130°C.
Compatibility and Operating Range
Designed for multi-media compatibility, the device works effectively with water, air, light oil, and vacuum conditions. It supports a wide operating pressure differential range, details of which can be referenced in the technical data sheets.
Variety of Sizes and Flow Capacities
Available in multiple port sizes ranging from 1/2" to 2", the diaphragm valve offers flow coefficients (Cv) between 4.5 and 48. This range ensures it meets various flow requirements across different applications.
Maximum Operating Pressure Differentials
The maximum operating pressure differential is rated up to 7 kgf/cm² for air, and up to 5 kgf/cm² for water and light oil. The device is also compatible with vacuum environments, broadening its usability.
Flexible Threaded Connections
Installation is facilitated by the availability of multiple threaded connection types including BSPT, NPT, and BSP, providing flexibility to suit different piping standards and system configurations.
Coil Voltage Stability
The coil supports a voltage tolerance of ±10% for AC and ±1% for DC, ensuring stable and reliable performance across voltage fluctuations.
Compact and Lightweight Design
Featuring a compact and lightweight design, the pilot diaphragm valve is easy to integrate into existing systems without adding significant bulk or complexity.
