About ASCO

ASCO is a brand of Emerson Electric Co., with a history in fluid automation and solenoid valve technology that dates back to the early 20th century. The product line includes solenoid valves, coils, and repair kits used to control the flow of air, inert gases, water, light oil, and other compatible media in industrial and commercial equipment. 3G Electric supplies ASCO solenoid valves and related components globally, with a catalog that includes 423 SKUs spanning multiple valve families, coil types, and replacement parts.

The ASCO product range covers 2-way and 3-way configurations in normally closed, normally open, and configurable arrangements. Pipe sizes in the supplied line start at 1/8 in and extend to 3/4 in, with additional sizes available across the broader catalog. Voltage options include 24V DC and 110V/120V AC, with wattages typically between 3 W and 11 W depending on the model. Body materials include brass and aluminum, and seal materials include NBR and FKM. Coil enclosures are available in watertight and conduit-hub styles, with some models supplied without a junction box and others with DIN connections. These specifications allow engineers to match valves to specific media, pressure, temperature, and environmental requirements.

Application categories for ASCO solenoid valves include on/off control of air and inert gases in pneumatic systems, water and light oil control in fluid-handling equipment, and remote pilot operation in process lines. The valves are used in industrial burners, pumps, gas controls, and related equipment where reliable actuation is required. Repair kits, such as the solenoid base sub-assembly kit compatible with the 8210G089 model, support on-site refurbishment and extend service life. Coils, including Type F and RedHat designs, are available as replacement components for existing installations.

3G Electric supports the ASCO line by stocking a range of solenoid valves, coils, and repair kits, and by providing product data such as pipe size, voltage, wattage, seal material, and body material to assist with specification and replacement. The catalog includes UL Listed repair kits and components with UNSPSC classifications for procurement systems. For technical buyers, 3G Electric offers access to ASCO part numbers, including MPNs such as 8212A038L1100F2 and SC8551A001MS, to facilitate cross-referencing and ordering. The company ships globally, serving plant engineers, maintenance managers, and procurement specialists who require ASCO components for new installations, maintenance, and repair.

Common Applications

Frequently asked questions

Common questions about ASCO from 3G Electric.

What ASCO solenoid valve configurations are available from 3G Electric?

3G Electric supplies ASCO solenoid valves in 2-way/2-position and 3-way/2-position configurations. These include normally closed, normally open, and configurable types. Pipe sizes range from 1/8 in to 3/4 in, with voltage options including 24V DC and 110V/120V AC. Body materials include brass and aluminum, and seal options include NBR and FKM. Coil enclosures vary from watertight to conduit hub, and some models feature DIN connections or remote pilot operation. The catalog includes specific part numbers such as 8212A038L1100F2 and SC8551A001MS.

Are ASCO RedHat coils available as replacement parts?

Yes, 3G Electric stocks ASCO RedHat coils and other ASCO coil types. For example, SKU 1AKJ8 is a Type F solenoid valve coil rated for 110V/120V AC with 6.1 W power consumption, featuring a watertight enclosure without junction box and 18-inch leads. These coils are used to actuate compatible ASCO solenoid valves. When ordering, verify the coil type, voltage, wattage, and enclosure style match the existing valve requirements.

What is included in the ASCO repair kit for solenoid valves?

The ASCO repair kit (SKU 2LBD7, MPN 302329) includes a solenoid base sub-assembly and other components for refurbishing the actuation assembly of compatible solenoid valves. The kit contains a cap retaining clip, retaining core assembly, diaphragm/seat, O-rings, retainer spring, solenoid base sub-assembly, and compression spring. It is UL Listed and compatible with the ASCO model 8210G089. This kit allows on-site repair and restoration of valve function in fluid-control systems.

What media can ASCO solenoid valves control?

ASCO solenoid valves supplied by 3G Electric are suitable for controlling air, inert gases, water, and light oil, depending on the valve model and seal material. For example, valves with FKM seals are used with water and light oil, while NBR seals are common for air and inert gases. Always confirm the valve's pressure and temperature ratings and seal compatibility with the specific media before installation.

How do I select the correct ASCO solenoid valve for my application?

Selection depends on the required configuration (2-way or 3-way, normally closed or normally open), pipe size, voltage, wattage, body material, seal material, and enclosure type. For remote pilot operation, ensure the pilot pressure and media are compatible. The ASCO catalog includes valves for high-pressure and high-temperature indoor applications, such as SKU 20HP29 with a 3/4 in pipe size and 120V AC coil. Review the specifications for each SKU to match your system requirements.
