Both single-coil and double-coil configurations are available, with installation possible in any orientation.
• Core Advantages & Applications: Featuring a hybrid design of rigid T-seals combined with flexible O-rings, it offers robust sealing abilities and excellent resistance to contamination, ensuring stable performance over millions of cycles. The valve carries multiple explosion-proof certifications including ATEX, UL, and CSA. It is well-suited for chemical engineering, oil refining, food and beverage processing, and life science industries.

2. 553 Series

Known also as the 8553 Series, this valve comes with a larger 1/2-inch port size and increased flow capacity compared to the 551 Series. It remains focused on managing air and inert gases efficiently.

• Key Parameters: It operates within a vacuum to 150 psi range. The flow capacity ranges from 2.0 to 6.0 Cv (1.73 to 5.19 Kv), offering superior flow performance. Voltage options align with those provided in the 551 Series, ensuring compatibility with various power sources. It is rated IP65 for protection and supports functional safety loops under SIL3, guaranteeing high safety standards.
• Structure & Materials: Constructed with valve bodies made of aluminum, brass, or 316L stainless steel. Port types follow G ISO228/1 - G BSPP and NPTF standards, while connections use 1/2-inch NPT and BSP threads. The valve supports two installation methods: actuator mounting with NAMUR interfaces per the VDI/VDE3845 standard or direct mounting to piping through threaded connections.
• Core Advantages & Applications: The exhaust port is pipeable, and NAMUR ports are conveniently placed on the same side, ensuring excellent dust and water resistance. It boasts waterproof and explosion-proof features and incorporates a low-power design suitable for remote power applications. Its rugged design makes it ideal for challenging industrial environments requiring high flow, such as chemical processing and oil refining.

3. 531 Series

The 531 Series is tailored to prioritize safety and reliability, offering options for both explosion-proof and non-explosion-proof configurations. It is primarily applied for actuator pilot control within chemical and hybrid industrial settings, with flagship models such as the SCG531C001MS.

• Key Parameters: This series operates from -0.95 bar to +10 bar and tolerates an ambient temperature range from -10℃ to +60℃. At 6 bar pressure, the flow rate reaches 1150 L/min (ANR). It features a G1/4 interface size, a 6mm port diameter, and a flow coefficient of 0.95 m³/h. Typical voltage options include 220VAC and 24VDC, with coil specifications exhibiting an inrush power of 6 VA and holding power of 3.5 VA.
• Structure & Materials: The valve body is made of black anodized aluminum, sealed with low-friction, non-sticking T-seals. The top cover and end caps consist of polyamide, while internal components combine acetal and aluminum. Electrical connections can be DIN or metal M12 types. Installation follows the NAMUR standard and the exhaust port is threaded to minimize impurity ingress.
• Core Advantages & Applications: Incorporating an internal air circulation design, it effectively prevents moisture penetration into the actuator and valve body to avoid corrosion. The valve complies with EN60730 safety standards and carries explosion-proof certifications such as ATEX and IECEx. Due to its exceptional cleanliness and stability, it is especially suitable for industries demanding high environmental purity, including pharmaceuticals and food production, as well as actuator pilot control within the chemical sector.
