These valves are widely used for gas control in sectors like chemical engineering and the food & beverage industry. Below is a comprehensive overview of each series’ characteristics and advantages.
Also known as the 8551 Series, the 551 series features 1/4-inch 3-way and 4-way compact solenoid spool valves. They are specifically engineered to manage air and inert gases in harsh and corrosive environments, making them ideal for demanding and hazardous conditions.
- Key Parameters: The operating pressure ranges from vacuum up to 150 psi. It supports medium temperatures between -60℃ and 80℃, with a flow range of 0.5 to 1.0 Cv (0.43 to 0.86 Kv). The series offers a variety of voltage options including both DC (6VDC, 12VDC, 24VDC, etc.) and AC voltages (24VAC, 110VAC, 220VAC, etc.) to suit different power supplies.
- Structure & Materials: Valve bodies come in anodized aluminum, brass, or optional stainless steel. The ports are available in G ISO228/1 - G BSPP and NPTF standards with connection options including 1/4-inch NPT and BSP threads. It supports multiple functional configurations such as 3/2 Normally Closed (NC), 4/2, 4/3 Center Closed (CC), and 4/3 Normally Open (NO). Both single-coil and double-coil designs are supported, with installation possible in any orientation.
- Advantages & Applications: The design integrates hard T-seals with flexible O-rings to ensure excellent sealing and dirt resistance, enabling reliable operation for millions of cycles. Certified under ATEX, UL, CSA, and other explosion-proof standards, the 551 series is well suited for industries such as chemical processing, oil refining, food & beverage, and life science manufacturing.
The 553 Series, or 8553 Series, is characterized by larger 1/2-inch ports and higher flow capacity compared to the 551. This series also targets air and inert gas control in industrial applications requiring increased throughput.
- Key Parameters: Operating pressure spans from vacuum to 150 psi, with a flow range of 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, accommodating various power scenarios. It includes an IP65 protection rating and supports functional safety loops up to and below SIL3, ensuring robust safety features.
- Structure & Materials: Valve bodies are available in aluminum, brass, and 316L stainless steel. Ports conform to G ISO228/1 - G BSPP and NPTF standards, connecting through 1/2-inch NPT or BSP threads. The valve can be installed either by mounting on actuators with NAMUR interfaces as per VDI/VDE3845, or by direct thread connection to piping.
- Advantages & Applications: The exhaust port is designed for piping and the NAMUR ports are positioned on the same side, enhancing dust and water resistance. This series boasts waterproof and explosion-proof properties alongside a low-power consumption design suitable for remote power applications. It is frequently employed in demanding industrial settings such as chemical plants and refineries, where higher flow rates are essential.
The 531 Series emphasizes safety and reliability, offering both explosion-proof and non-explosion-proof configurations. It primarily serves actuator pilot control needs within chemical and hybrid industries, with popular models like the SCG531C001MS.
- Key Parameters: This series operates within a pressure range of -0.95 bar to +10 bar and an ambient temperature range of -10℃ to +60℃. At 6 bar, it supports a flow rate of 1150 L/min (ANR). The interface size is G1/4, with a port diameter of 6 mm and a flow coefficient of 0.95 m³/h. Common voltage options include 220VAC and 24VDC, featuring a coil inrush power of 6 VA and a holding power of 3.5 VA.
- Structure & Materials: The valve body is crafted from black anodized aluminum, with low-friction, non-sticking T-seals. The top cover and end caps are made of polyamide, while internal parts utilize acetal and aluminum. Electrical connections support DIN or metal M12 types. The valve is NAMUR-compatible, with a threaded exhaust port designed to minimize impurity ingress.
- Advantages & Applications: Its internal air circulation design prevents moisture ingress into the actuator and valve body, protecting against corrosion. Certified according to EN60730 and explosion-proof standards such as ATEX and IECEx, the 531 series delivers exceptional cleanliness and operational stability. This makes it ideal for environments with rigorous cleanliness demands like pharmaceutical and food industries, in addition to its use in chemical actuator pilot control.
