Asco 4-way Solenoid valves have Four ported valves which are generally used to operate double-acting cylinders or actuators.

Sitemap

4-way Solenoid valves have four or five pipe connections, commonly called ports:

One pressure inlet

Two cylinder ports providing pressure to the double-acting cylinder or actuator

One or two outlets to exhaust pressure from the cylinders.

In a de-energized position, pressure is connected to one cylinder port; the other port is connected to the exhaust. In an energized position, pressure and exhaust are reversed.

Four ports means less piping is required. With five ports,independent speed controls can be mounted in each port

Three Types of Operations Apply

Single Solenoid

Dual Solenoid

Single Air Operator

When the solenoid is energized, the valve shifts, then returns to the original position when de-energized.

When one solenoid is energized,the valve shifts, then returns when the other solenoid is energized. They may be energized momentarily or continuously,but never concurrently. Some valves, both single and dual solenoid, may change position on loss of fluid pressure.

When the operator is pressurized,the valve shifts, then returns when the pressure is removed.

Standard Optional Features

Solenoid valves are supplied, as listed, with either Red-Hat II molded epoxy solenoids or Red-Hat solenoids with metal enclosures.Red-Hat II valves are identified by the letter "G" or "H" in their catalog numbers e.g., 8344G27. Many optional features may be added to your valves; e.g.,high-temperature Class H molded coils, manual operators, and metering devices. See the OptionalFeatures Section for details.
