The ASCO Series 553 features a range of compact solenoid spool valves, designed specifically for managing air or inert gases in demanding settings. These valves are equipped with a unique combination of hard T-seals and flexible O-rings, ensuring a bubble-tight closure, resistance to dirt, and enduring reliability over millions of cycles. The 551 Series is available in anodized aluminium, brass, and stainless steel constructions, offering ½-inch NPT and BSP connections. This makes them ideally suited for the rigorous environments typical in chemical, refining, food and beverage industries, as well as life science processing.

Key features and benefits of ASCO™ Series 553 Solenoid Spool Valves

Key Features

The design of the exhaust ports allows them to be connected to piping systems. This feature enhances the valve's ability to resist harsh environmental conditions, such as dust, moisture, or corrosive substances, making it more suitable for use in challenging industrial settings. By controlling the exhaust flow through pipes, the valve's internal components are less exposed to environmental wear and tear.

Key Features

A range of solenoid options is offered, including DIN connectors, watertight, and explosion-proof models. These solenoids are specifically designed for applications in areas where reliability is essential and where the presence of flammable or explosive substances creates a hazardous environment. Their construction ensures that they can function safely and effectively, reducing the risk of failure in high-risk locations.

Key Features

The valves are available in low-power configurations, making them well-suited for use in remote areas or locations where power supply is limited or needs to be sourced from alternative energy systems. This makes them an energy-efficient choice, enabling prolonged operation in areas where consistent access to traditional power sources may be a challenge.
