Product Description:
The ASCO solenoid valve lineup offers an extensive selection of high-performance valves designed to ensure reliable fluid and pneumatic control. This range includes 2/2-way, 3/2-way, and 5/2-way solenoid valves tailored for various demanding environments such as industrial automation, process control, and hazardous area applications.
Within this portfolio, pilot-operated spool valve designs like the 531, 551, 553, and 8551 series cater to high-flow pneumatic needs. For scenarios requiring dependable operation without differential pressure, the direct-acting 320 series valves are ideal. Furthermore, pilot-operated diaphragm valves, including the 8210 and 8262 series, are engineered to manage general-purpose liquid and gas control applications effectively.
The product range supports port sizes from 1/4 inch up to 1 inch and is manufactured using various body materials such as aluminum, brass, and stainless steel. This diversity allows for versatile applications involving clean air, inert gases, water, light oils, and even corrosive media. Additionally, valve configurations include 2/2-way normally closed or normally open, 3/2-way universal options, and 5/2-way valves with either single or double solenoids, featuring spring return or bistable functions.
Notably, the 551 and 8551 series boast a unique convertible flow plate design, enabling a single valve to operate as either a 3/2-way or a 5/2-way valve, providing enhanced flexibility for various system requirements.
Many ASCO valve models incorporate the NAMUR mounting interface in compliance with VDI/VDE 3845 standards, facilitating direct actuator mounting. They also offer robust protection with IP65, IP66, and IP67 ratings. For applications within explosive environments, certified explosion-proof versions are available, holding ATEX, IECEx, UL, and CSA approvals. These also include low-power designs suited for remote or alternative power scenarios.
Trusted by industries worldwide, ASCO solenoid valves are recognized for their reliable, durable performance, rapid response times, and minimal internal leakage, making them a preferred choice in fluid and pneumatic control solutions.
