Product Description:

Features:

The product lineup includes a wide variety of series such as 531, 551, 553, 8320, 8210, 8551, 8262, and the 320 series. This extensive range ensures suitability for diverse application requirements across different industries.

Multiple valve types are offered, including 2/2-way (normally closed or normally open), 3/2-way universal, and 5/2-way options with either single or double solenoids. These configurations provide flexibility to meet specific functional demands.

A unique feature of the 551 series valves is their convertible flow plate design, allowing them to be easily switched from 3/2-way to 5/2-way operation using just a single flow plate, enhancing adaptability.

The valves are manufactured using multiple body materials including aluminum with black anodized finish, brass, and stainless steel (316L). This variety supports compatibility with different media and environmental conditions.

Port sizes range from 1/4 inch up to 1 inch, and thread types available include G, NPT, and BSP, offering versatility in installation and connection.

Valves are designed to support direct actuator mounting in accordance with the VDI/VDE 3845 standard, facilitating straightforward integration with automation systems.

For pneumatic applications requiring high flow rates, pilot-operated spool valves are available. Additionally, direct-acting valves offer reliable performance even without differential pressure.

Both single solenoid (spring return, monostable) and double solenoid (bistable) construction options are available, ensuring suitable control for different operational scenarios.

Flow rates can reach up to 700 liters per minute for 1/4 inch models and up to 3000 liters per minute for 1/2 inch models, supporting high throughput requirements.

Operating pressures span from 2 to 10 bar in pneumatic series and can go up to 24 bar for liquid services. Temperature ranges cover from -25°C to +60°C in standard versions, with Arctic variants capable of operating down to -60°C.

The valves offer multiple protection classes including IP65, IP66, and IP67, ensuring durability and reliability in harsh environmental conditions.

Various hazardous area certifications are achieved, such as ATEX, IECEx, UL, CSA, NEPSI, KOSHA, and InMetro approvals, assuring compliance with international safety standards.

Designed to operate at low power levels, some constructions consume as little as 1.7W, making them ideal for remote locations and alternative power sources.

Pipeable exhaust ports are incorporated to offer better protection against harsh environments, extending the lifespan of the valves.

Many models come equipped with a standard manual override feature to facilitate easy commissioning and maintenance procedures.

Lead-free and drinking water compliant versions are available to meet regulations under the Safe Drinking Water Act, ensuring safe usage in potable water applications.

The 551-553 series valves have TÜV and EXIDA certifications with Safety Integrity Levels (SIL) 2 (with Hardware Fault Tolerance HFT=0) and SIL 3 (HFT=1), guaranteeing reliable performance in safety-critical systems.
