Product Description:
The ASCO solenoid valve portfolio offers an extensive selection of high-performance valves designed for fluid and pneumatic control. This range includes 2/2-way, 3/2-way, and 5/2-way solenoid valves tailored to meet the demands of industrial automation, process control, and hazardous area applications. The valves come in various designs such as pilot-operated spool valves (531, 551, 553, 8551 series) optimized for high-flow pneumatic uses, direct-acting valves (320 series) that provide dependable operation without requiring differential pressure, and pilot-operated diaphragm valves (8210, 8262 series) suitable for general liquid and gas control services.
Covering port sizes from 1/4" up to 1", the product line features diverse body materials like aluminum, brass, and stainless steel. These options make the valves ideal for handling clean air, inert gases, water, light oils, and even corrosive media. The configurations include 2/2-way valves that are either normally closed or normally open, 3/2-way universal valves, and 5/2-way valves with either single or double solenoids, equipped with spring return or bistable operation. Notably, the 551 and 8551 series incorporate a unique convertible flow plate, enabling a single valve to operate as both a 3/2-way or 5/2-way valve.
Many of these valve models are designed with NAMUR mounting interfaces in compliance with VDI/VDE 3845 standards, allowing direct actuator attachment. They also provide robust protection levels rated at IP65, IP66, and IP67. For safety in hazardous locations, explosion-proof versions carry certifications such as ATEX, IECEx, UL, and CSA. Additionally, low-power designs are available to support remote locations and alternative power sources. Globally trusted across various industries, ASCO solenoid valves ensure reliable, durable performance, featuring quick response times and minimal internal leakage.
