ASCO Solenoid Valve SCB320B174 EF8320G174 1/4 Inch Port 3/2 Way Single Coil Pneumatic Air Directional Control Valve Industrial Automation Spare Parts

Product Description:

The ASCO solenoid valve portfolio offers an extensive selection of high-performance valves designed to provide reliable control in various settings such as industrial automation, process control, and hazardous area applications. This diverse range includes multiple series, each tailored to meet specific operational requirements.

The 551 and 8551 Series consist of pilot-operated spool valves that excel in pneumatic control applications. These valves come equipped with a NAMUR interface and feature a convertible design enabling a single valve to function either as a 3/2-way or 5/2-way valve. They are compatible with both single-acting and double-acting actuators, making the 551 series an extremely versatile platform for pneumatic systems.

The 8320 and 320 Series include direct-acting and some pilot-operated 3/2-way valves suitable for a wide range of general service applications. A key characteristic of these valves is their ability to operate effectively without requiring a minimum pressure differential.

For liquid, corrosive, and air or inert gas service, the 8210 and 8262 Series offer pilot-operated 2/2-way valves. The 210/8210 series is recognized for delivering economical yet high-flow performance, whereas the 8262 series provides a sturdy and durable 2/2-way valve option.

The 531 Series comprises spool valves capable of 3/2 or 5/2 functions, frequently available with intrinsically safe (IS) options, ensuring safety in hazardous environments. Additionally, the 210 Series, featuring models like the 8210G094, is crafted for both liquid and gas service applications.

These valves are manufactured using a variety of body materials, including aluminum with black anodizing, brass, and stainless steel (316L). They also offer different seal options such as NBR, PUR, and FKM. The configurations span 2/2-way, 3/2-way, and 5/2-way designs, accompanied by single and double solenoid constructions to provide spring return or bistable operation modes.

Many models incorporate NAMUR mounting interfaces and boast protection ratings of IP65, IP66, or IP67. For use in demanding and hazardous environments, explosion-proof versions are available with certifications including ATEX, IECEx, UL, and CSA. Low-power variants are also offered to suit specific application needs.

Features:

These spool valves feature a NAMUR interface with threaded port connections, allowing for direct mounting of actuators. Their design offers versatility, as the same valve can be configured to function as either a 3/2 normally closed (NC) or a 5/2 valve.

All exhaust ports on these valves can be connected, which enhances environmental protection, making them especially suitable for clean room applications. In terms of safety, the 551 series holds TÜV certification, while the 551-553 series is certified by EXIDA. Both provide safety integrity levels of SIL 2 (with hardware fault tolerance HFT=0) and SIL 3 (HFT=1).

Additionally, these valves come equipped with a standard manual operator to facilitate easy commissioning and maintenance.

The 8320 and 320 series are designed for a broad range of general service applications. These direct-acting valves do not require a minimum pressure differential to operate, increasing their usability across various scenarios.

They can be installed in any orientation, providing versatile mounting options that accommodate different system configurations.

These valves provide economical solutions with high flow capacities, suitable for handling liquids, corrosive substances, as well as air and inert gases. Their robust construction comes in brass or stainless steel bodies, enabling compatibility with diverse media types.

The 531 series offers flexible functionality, available in both 3/2-way and 5/2-way configurations. They are intrinsically safe and certified for operation in hazardous environments by limiting current and voltage, ensuring a high level of safety.

The valve bodies across these series are available in multiple materials including aluminum, brass, and stainless steel, catering to various application requirements. They also support a range of voltages such as DC24V, AC24V, AC120V, AC220V, among others.

For hazardous areas, explosion-proof options are offered with ATEX and IECEx certifications. Low power variants are also available, making them suitable for remote locations or alternative power setups.

Regarding flow performance, the 1/4" models typically deliver flow rates around 700 liters per minute, while the 1/2" models can reach up to 3000 liters per minute.
