The product line encompasses a wide range of series including the 531, 551, 553, 8320, 8210, 8551, 8262, and 320 series, catering to diverse application needs.

Various valve configurations are offered, such as 2/2-way (normally closed or normally open), 3/2-way universal, and 5/2-way options featuring both single and double solenoids.

The 551 series valves feature a convertible flow plate design, allowing easy conversion from 3/2-way to 5/2-way operation with the installation of a single flow plate.

To ensure compatibility with various media, the valves are available in different body materials including black anodized aluminum, brass, and stainless steel (316L).

The range of port sizes extends from 1/4 inch to 1 inch, with threading options such as G, NPT, and BSP to suit different connection requirements.

Actuators can be mounted directly following the NAMUR standard, compliant with VDI/VDE 3845, facilitating standardized installation.

For pneumatic applications requiring high flow, pilot-operated spool valves are available. Meanwhile, direct-acting valves ensure reliable function without the need for differential pressure.

Both spring return (monostable) and bistable (dual solenoid) designs are offered to meet different operational demands.

The valves support high flow rates, reaching up to 700 liters per minute in 1/4 inch models and up to 3000 liters per minute in 1/2 inch models.

Operating pressures range from 2 to 10 bar for pneumatic series, with capabilities extending up to 24 bar for liquid service applications.

Standard versions operate between -25°C and +60°C, while Arctic variants function reliably down to -60°C, supporting use in extreme environments.

Protection ratings include IP65, IP66, and IP67, ensuring durability and resistance to dust and water ingress.

These valves meet safety standards for hazardous locations with certifications including ATEX, IECEx, UL, CSA, NEPSI, KOSHA, and InMetro.

Designed for remote and alternative power scenarios, certain models operate with power consumption as low as 1.7 watts.

Equipped with pipeable exhaust ports, the valves provide enhanced protection against harsh environmental conditions.

Many models come standard with a manual override feature, facilitating easy commissioning and maintenance procedures.

Versions compliant with the Safe Drinking Water Act regulations are available, ensuring suitability for potable water applications.

The 551-553 series hold TÜV and EXIDA certifications, offering SIL 2 (with hardware fault tolerance HFT=0) and SIL 3 (HFT=1) integrity levels, attesting to their safety and reliability.

Pneumatic actuator control is achieved through direct NAMUR mounting on quarter-turn actuators, suitable for both double-acting and single-acting types. This setup provides precise and reliable operation for various industrial applications.
