Product Description:
The ASCO solenoid valve portfolio offers an extensive selection of high-performance valves designed for dependable control in various fields such as industrial automation, process control, and applications within hazardous environments. This comprehensive range includes multiple series, each tailored to meet specific operational requirements.
The 551 and 8551 Series consist of pilot-operated spool valves that are ideal for pneumatic control systems. These valves incorporate a NAMUR interface and a versatile design, enabling a single unit to function as either a 3/2-way or 5/2-way valve. This flexibility makes them suitable for use with both single-acting and double-acting actuators. Particularly, the 551 series provides a highly adaptable foundation for pneumatic applications.
The 8320 and 320 Series feature direct-acting, along with some pilot-operated, 3/2-way valves engineered for a wide variety of general service uses. These valves are capable of operating efficiently without the need for a minimum pressure differential, broadening their usability across many scenarios.
Included in the portfolio are the 8210 and 8262 Series, which are pilot-operated 2/2-way valves intended for general service involving liquids, corrosive substances, and air or inert gases. The 210/8210 series is recognized for its cost-effective, high-flow capabilities, while the 8262 series offers a robust and durable 2/2-way valve solution.
The 531 Series provides spool valves with 3/2 or 5/2-way functions and often includes intrinsically safe (IS) options, making them suitable for sensitive environments. The 210 Series features models such as the 8210G094, which are designed specifically for liquid and gas service applications.
ASCO solenoid valves are manufactured using various body materials including black anodized aluminum, brass, and stainless steel (316L), and are equipped with seal options such as NBR, PUR, and FKM. Available configurations include 2/2-way, 3/2-way, and 5/2-way valves, with both single and double solenoid designs offering spring return or bistable operation modes. Many models comply with the NAMUR mounting standard and provide protection ratings of IP65, IP66, and IP67.
For demanding and hazardous applications, explosion-proof versions are offered, certified by ATEX, IECEx, UL, and CSA. Additionally, there are low-power variants designed to meet the rigorous demands of such environments, ensuring safety and reliability in critical operations.
Features:
551 / 8551 Series (Spool Valves)
The 551 and 8551 series feature NAMUR interfaces with threaded port connections, allowing for direct mounting onto actuators. This design ensures seamless integration and ease of installation.
These spool valves are highly versatile, as the same unit can be configured to function as either a 3/2 normally closed valve or a 5/2 valve, adapting to a variety of applications.
All exhaust ports are pipable and connectable, enhancing environmental protection measures, which is especially beneficial in clean room environments where contamination must be minimized.
Safety is paramount in this series, with certifications from TÜV for the 551 series and EXIDA for the 551-553 series. These valves meet safety integrity levels SIL 2 with no hardware fault tolerance (HFT=0) and SIL 3 with one hardware fault tolerance (HFT=1).
A standard manual operator is included to facilitate straightforward commissioning and maintenance processes.
8320 / 320 Series (Direct-Acting)
The 8320 and 320 series are designed to cover a broad range of general-service applications, making them highly adaptable components in various systems.
One significant advantage of these direct-acting valves is that they require no minimum pressure difference to operate effectively, allowing for flexible installation and use.
Additionally, these valves can be installed in any orientation, providing greater versatility in system design and layout.
8210 / 8262 Series (General Service)
This range consists of economical, high-flow valves suitable for handling liquids, corrosive substances, as well as air and inert gases.
The valves come with durable construction options, featuring bodies made from either brass or stainless steel to accommodate different media and environmental conditions.
531 Series
The 531 series offers flexibility in function, available in both 3/2-way and 5/2-way configurations to meet varying operational requirements.
These valves are intrinsically safe, certified for use in hazardous locations due to their limited current and voltage, ensuring safety in critical environments.
Across All Series
Across all the valve series mentioned, multiple material options are available, including aluminum, brass, and stainless steel, catering to diverse application needs and environmental conditions.
They support various voltage options such as DC24V, AC24V, AC120V, and AC220V, among others, providing flexibility in electrical integration.
Explosion-proof versions are available with ATEX and IECEx certifications, making these valves suitable for use in potentially explosive atmospheres.
Low power variants are offered as well, which are ideal for installations in remote locations or applications with limited power availability.
High flow rates are a feature of these valve series, with 1/4-inch models typically delivering up to 700 liters per minute, and 1/2-inch models capable of handling up to 3000 liters per minute.
