Product Description:
The ASCO solenoid valve range includes a diverse selection of high-performance 2/2-way, 3/2-way, and 5/2-way valves. These valves are designed to provide dependable fluid and pneumatic control, suitable for various sectors including industrial automation, process management, and hazardous area environments. The portfolio features pilot-operated spool valve models (such as the 531, 551, 553, and 8551 series) tailored for high-flow pneumatic systems. Additionally, direct-acting valves (320 series) ensure reliable function even without differential pressure, while pilot-operated diaphragm valves (8210 and 8262 series) serve general liquid and gas control applications.
Port sizes range from 1/4" to 1", with multiple body material options including aluminum, brass, and stainless steel. This variety accommodates applications involving clean air, inert gases, water, light oils, and corrosive fluids. The valves are available in different configurations, such as 2/2-way normally closed and normally open, 3/2-way universal types, and 5/2-way models with either single or double solenoids featuring spring return or bistable operations. Notably, the 551 and 8551 series incorporate a convertible flow plate design, enabling a single valve to operate flexibly as either a 3/2-way or a 5/2-way valve.
Many valve models include NAMUR mounting interfaces according to VDI/VDE 3845 standards, facilitating direct actuator attachment. They also meet protection ratings of IP65, IP66, and IP67. Explosion-proof versions carry certifications such as ATEX, IECEx, UL, and CSA, with options for low-power designs suitable for remote locations or alternative power sources. ASCO solenoid valves are trusted worldwide, recognized for their dependable, durable performance, fast response times, and minimal internal leakage.

Mounting, Operation, and Control
The series supports NAMUR mounting interfaces compliant with the VDI/VDE 3845 standard for direct actuator mounting. Both pilot-operated spool valves, ideal for high-flow pneumatic applications, and direct-acting valves, which function reliably without differential pressure, are offered. Additionally, customers can choose from single solenoid spring return (monostable) and dual solenoid bistable constructions.
Performance and Environmental Capabilities
These valves provide high flow capacities, reaching up to 700 liters per minute for 1/4-inch models and 3000 liters per minute for 1/2-inch models. They operate within wide pressure ranges, from 2 to 10 bar for pneumatic applications, extending up to 24 bar for liquid service. Temperature ranges are also broad, from standard -25°C up to +60°C, with Arctic versions capable of functioning at temperatures as low as -60°C.
Protection, Certifications, and Special Features
Protection classes include IP65, IP66, and IP67, ensuring durability in harsh environments. Safety certifications for hazardous areas cover ATEX, IECEx, UL, CSA, NEPSI, KOSHA, and InMetro standards. Low-power versions, consuming as little as 1.7 watts, are designed for remote and alternative power scenarios. Additional features include pipeable exhaust ports for enhanced environmental protection, standard manual overrides on many models for straightforward commissioning and maintenance, as well as lead-free and drinking water compliant options to meet Safe Drinking Water Act requirements.
Safety Integrity Level (SIL) Certification
The 551-553 series are TÜV and EXIDA certified, achieving Safety Integrity Levels SIL 2 (with hardware fault tolerance HFT=0) and SIL 3 (with HFT=1), offering reliable performance for safety-critical applications.
