Double Solenoid Type ASCO Solenoid Valve SCG551A017MS SCG551A018MS 5/2 Way Pneumatic Solenoid Valve Single/Double Coil Pilot Operated Thread Connection 1/4 Inch

Product Description:

The ASCO solenoid valve portfolio offers an extensive selection of high-performance valves, including 2/2-way, 3/2-way, and 5/2-way configurations. These valves are specifically designed to provide dependable fluid and pneumatic control solutions across various sectors such as industrial automation, process control, and hazardous area environments. Within this portfolio, pilot-operated spool valve designs like the 531, 551, 553, and 8551 series cater to high-flow pneumatic needs, while the 320 series utilizes direct-acting designs to ensure dependable operation even in the absence of differential pressure. Additionally, pilot-operated diaphragm models such as the 8210 and 8262 series are ideal for general service applications involving liquids and gases.

The comprehensive product lineup accommodates port sizes ranging from 1/4 inch to 1 inch, with valve bodies constructed from materials including aluminum, brass, and stainless steel. This variety ensures compatibility with a broad range of media such as clean air, inert gases, water, light oils, and corrosive substances. Valve options encompass 2/2-way configurations that can be normally closed or normally open, 3/2-way universal valves, and 5/2-way models featuring single or double solenoids with either spring return or bistable operation. Notably, the 551 and 8551 series incorporate an innovative convertible flow plate design, enabling a single valve to function flexibly as either a 3/2-way or 5/2-way valve.

Many valves are equipped with NAMUR mounting interfaces compliant with the VDI/VDE 3845 standard, facilitating direct actuator attachment. Protection ratings including IP65, IP66, and IP67 ensure robust performance in challenging conditions. For hazardous environments, explosion-proof versions are available, certified by ATEX, IECEx, UL, and CSA. Furthermore, low-power variants enable installation in remote or alternative power supply locations. Trusted by industries worldwide, ASCO solenoid valves are renowned for delivering reliable, durable operation with rapid response times and minimal internal leakage.

Features:

Our product line includes a wide range of series such as the 531, 551, 553, 8320, 8210, 8551, 8262, and 320 series. These options cater to diverse application requirements, ensuring that there is a suitable solution for every need.

The valves are available in multiple configurations including 2/2-way (normally closed or normally open), 3/2-way universal, and 5/2-way functions with single or double solenoids. A notable feature of the 551 series is its convertible flow plate design, allowing easy conversion from 3/2-way to 5/2-way with just a single flow plate.

To support compatibility with various media, the valves come in multiple body materials including aluminum with black anodizing, brass, and stainless steel (316L). Port sizes are offered in a wide range from 1/4" to 1" equipped with G, NPT, and BSP thread options, enhancing flexibility for different piping standards.

The products feature a NAMUR mounting interface, enabling direct actuator installation according to the VDI/VDE 3845 standard. Both pilot-operated spool valves and direct-acting valves are available; the pilot-operated type suits high-flow pneumatic applications, whereas direct-acting valves provide dependable operation even without differential pressure.

Offering both single solenoid spring return (monostable) and double solenoid bistable (dual solenoid) construction options, these valves deliver high flow capacity with flow rates reaching up to 700 L/min for 1/4" models and 3000 L/min for 1/2" models. They can handle wide operating pressures, from 2 to 10 bar in pneumatic series, and up to 24 bar for liquid service applications.

The valves are designed to operate across a broad temperature range, from standard conditions of -25°C to +60°C, with arctic versions available for operation down to -60°C. Protection classes include IP65, IP66, and IP67 options. Additionally, numerous hazardous area certifications are obtained such as ATEX, IECEx, UL, CSA, NEPSI, KOSHA, and InMetro approvals.

Low-power constructions are ideal for remote or alternative power locations, with power consumption as low as 1.7W. The valves feature pipeable exhaust ports for enhanced protection against harsh environments, and many models include a manual override for simple commissioning and maintenance.

Versions compliant with lead-free and drinking water regulations are available to meet Safe Drinking Water Act standards. Furthermore, select models like the 551-553 series are SIL certified by TÜV and EXIDA, achieving safety integrity levels SIL 2 (with hardware fault tolerance 0) and SIL 3 (with hardware fault tolerance 1), ensuring high reliability in safety-critical applications.
