ASCO 2-Way Solenoid Valves have one inlet and one outlet, and are used to permit and shut off fluid flow. The two types of operations are “Normally Closed” and “Normally Open”.

ASCO 3-Way Solenoid Valves  have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. 3-way solenoid valves are commonly used to alternately apply pressure to and exhaust pressure from a valve actuator or a single acting cylinder. The RedHat solenoid valve can be normally closed, normally open or universal.

ASCO 4-Way Solenoid Valves have four or five pipe connections, commonly called ports. One pressure inlet, two cylinder ports providing pressure to double acting cylinder or actuator, and one or two outlets to exhaust pressure from the cylinders.
Direct Mount ASCO Valves  are standard 3-way and 4-way RedHat solenoid valves whose NPT pipe connections and mounting configurations have been replaced by NAMUR mounting configuration. This allows each valve to be mounted directly to an actuator without the use of hard piping or tubing.

Dust Collector Valves  are high-flow fast-opening 2-way RedHat valves, pilot valves, pilot valve enclosures and bulkhead fittings that have been specially designed for use in dust collector systems.

Group Mounted Position Valves are 2-way, 3-way and 4-way 2-position valves that are designed for gang mounting into different quantities of valves. Any combination of normally closed, normally open or universal valves may be grouped together.

Manual Reset Valves are standard 2-way, 3-way and 4-way 2-position valves that use a manual reset assembly in replacement of the solenoid. They are designed to prevent inadvertent valve startup in their designed failure modes. These series are available in no voltage release, electrically tripped, and free handle constructions as well as latched open or latched closed for 2-way valves.

Medical/Analytical ASCO Miniature general service, isolation, pinch, and proportional valves are utilized for the precise and reliable control of liquids and gases in medical equipment and analytical instrumentation.

ASCO S Series  are developed and engineered with ASCO's global resources. ASCO S is a compact solution for 2-way, 3-way and steam valve applications and can operate in 15°F to 125°F ambient temperature locations. This solution includes DIN connection for easy wiring, compact brass bodies and encapsulated coils. Options include 15" leads, alternate elastomers, manual operators, and mounting brackets.

Options/Accessories ASCO offers a wide variety of accessories and optional features to meet your specific application requirements.
