The ASCO SCG551A001MS is a high - performance solenoid valve belonging to the 551 Series, which is also known as the 8551 Series. It is a 1/4 - inch 3 - way and 4 - way compact solenoid spool valve, designed for precisely controlling air or inert gas in challenging industrial environments.

Key Features

Design & Construction:

Body Material: Available in anodized aluminum, brass, and stainless steel, offering excellent corrosion resistance.

Connection Type: Equipped with ¼ - inch NPT and BSP connections, ensuring easy installation and reliable sealing.

Unique Seal Design: The combination of hard T - seals and flexible O - rings provides bubble - tight shutoff, dirt resistance, and multi - million - cycle reliability.

Functional Specifications:

Versions: Offered in two versions, which can be directly mounted to actuators with a NAMUR interface per VDI/VDE 3845 or threaded to mount on the pipe.

Solenoid Options: DIN, watertight, and explosion - proof solenoids are available, suitable for mission - critical and hazardous areas. It provides single - and dual - solenoid constructions that can be mounted in any position.

Low - Power Design: The low - power construction is suitable for remote and alternative power locations.

Special Version: An arctic version is available, which can be used in temperatures as low as - 60 °C.

Performance:

Media Compatibility: Ideal for controlling air or inert gas.

Flow Capacity: With a compact spool valve design that can be converted from 3/2 to 5/2 using a single - flow plate design (only in the 551 Series), it has a good flow capacity. The Cv value ranges from 0.5 to 1.0, and the Kv value ranges from 0.43 to 0.86.
