Product Description:
ASCO 551, 553, 531 Series Solenoid Valves
The ASCO 551, 553, and 531 series consist of compact spool-type solenoid valves, each tailored to distinct application scenarios through variations in specifications such as port size and flow capacity. Widely utilized for gas control across multiple sectors— including chemical processing and the food and beverage industry—these valve series provide reliable performance in diverse environments. The following sections provide an in-depth overview of the characteristics and applications of each series.
Known also as the 8551 Series, the 551 model is a 1/4-inch, 3-way and 4-way compact solenoid spool valve. It is engineered specifically for air and inert gas control in demanding and corrosive environments, making it suitable for use in challenging industrial conditions.
- Key Parameters: This valve operates within a pressure range from vacuum up to 150 psi and accommodates medium temperatures between -60℃ and 80℃. Its flow capacity ranges from 0.5 to 1.0 Cv (0.43 to 0.86 Kv). Voltage options include various DC voltages (6VDC, 12VDC, 24VDC, etc.) and AC voltages (24VAC, 110VAC, 220VAC, etc.), allowing flexibility for different power supplies.
- Structure & Materials: The valve body is available in anodized aluminum, brass, or stainless steel (optional), and it features port types compatible with G ISO228/1 - G BSPP and NPTF standards. Connections are offered in 1/4-inch NPT and BSP threads. The series supports multiple functional configurations such as 3/2 normally closed (NC), 4/2, 4/3 center closed (CC), and 4/3 normally open (NO) modes. Both single-coil and double-coil setups are supported, with installation possible in any orientation.
- Core Advantages & Applications: This series incorporates a hybrid sealing design combining durable T-seals with flexible O-rings, ensuring excellent sealing reliability and resistance to contaminants. It guarantees millions of stable operational cycles and holds certifications including ATEX, UL, and CSA for explosion-proof performance. Typical applications include chemical engineering, oil refining, food and beverage processing, and life sciences.
Also designated as the 8553 Series, this model features a larger 1/2-inch port size and enhanced flow capabilities compared to the 551 Series. Designed primarily for air and inert gas control, it meets the needs of applications requiring higher throughput.
- Key Parameters: The operating pressure spans from vacuum to 150 psi, with a flow range between 2.0 to 6.0 Cv (1.73 to 5.19 Kv), providing superior flow performance. Voltage options align with those of the 551 Series to accommodate multiple power scenarios. Additionally, it complies with an IP65 protection rating and supports functional safety loops up to SIL3, ensuring high safety standards.
- Structure & Materials: The valve body options include aluminum, brass, and 316L stainless steel. Port standards adhere to G ISO228/1 - G BSPP and NPTF, with 1/2-inch NPT and BSP thread connections. For installation, the series supports two methods: mounting on actuators equipped with NAMUR interfaces according to the VDI/VDE3845 standard, or direct pipe mounting using threaded connections.
- Core Advantages & Applications: The exhaust port is designed to be piped, and NAMUR ports are positioned on the same side, enhancing resistance to dust and water ingress. Its waterproof and explosion-proof features, combined with a low power requirement, make it well suited for remote power supply environments. It is commonly applied in demanding industrial sectors such as chemical processing and refining operations where high flow rates are essential.
The 531 Series focuses on safety and reliability, offering both explosion-proof and non-explosion-proof variants. It is primarily employed for pilot control of actuators in chemical and hybrid industries, with models like the SCG531C001MS being prominent examples.
