Solenoid valves

ASCO 210 is a high-flow solenoid valve series for liquids, corrosive media, air, and inert gases.
With a wide range of pressure ratings, sizes, and durable materials, these reliable two-way valves offer long service life and low internal leakage.
Industrial applications include car washes, air compressors, pumps, laundry equipment, and industrial water control.

ASCO 238 is a general-purpose valve series designed for use with air, inert gas, water, and light oil.
Its compact two-way pilot-operated design saves space, shortens installation time, and simplifies servicing, while its short stroke extends lifespan.
Suitable for air suspension systems, commercial kitchen and laundry equipment, packaging systems, and water/wastewater systems.

ASCO 327 is a high-flow pilot valve series that does not require minimum operating pressure.
Its balanced poppet design enables high flow rates at low power levels, ideal for power plants, refineries, and chemical facilities.
PTFE sealing rings and graphite-filled seals reduce friction and eliminate sticking, ensuring exceptional durability.


ASCO 551 is a compact solenoid spool valve series ideal for controlling air or inert gas in demanding environments.
Its unique design combines rigid T-seals and flexible O-rings for bubble-tight shutoff, dirt resistance, and long-term reliability over millions of cycles.
Available in anodized aluminum, brass, and stainless steel with ¼" NPT and BSP connections.
Suitable for harsh conditions in chemical, refining, food & beverage, and life sciences industries.

ASCO 353 is a pilot-operated diaphragm valve series designed for extremely fast pulsing in reverse-flow dust collector systems.
With high flow rates, higher max pressure, and faster response times, it delivers optimal filter cleaning performance while consuming significantly less air – resulting in energy savings.
Features include long service life, extended temperature range, and quick installation via patented Quick Mount Clamp connection.

ASCO 256 solenoid valves are designed for shutoff control in a wide range of industrial and commercial applications.
They carry multiple third-party approvals for applications from oil and gas burners to potable water and food service.
Compact design fits tight spaces, can be mounted in any position, and is available in various manifold configurations.
Ideal for bottling lines, commercial kitchens, laundries, and heating systems.

ASCO 356 solenoid valves feature a lightweight, compact design for controlling single-acting actuators or fill/drain cycles.
Brass or stainless steel constructions offer a wide range of elastomers and tight shutoff cones for specialized service applications.
