Extended-Life Sealed Linear Solenoids
In addition to a closed steel housing that keeps out dust, these solenoids have a PTFE coating on the rod to minimize friction for a long service life. All are pull solenoids—they exert force when the rod retracts.

Water-Resistant Sealed Linear Solenoids
Great for use in damp and dirty environments, these solenoids meet IP65 for protection from dust and spraying water. They have two-pin plugs that are compatible with Deutsch-style DC connectors (sold separately). They can be used to pull or push. To pull, install them with the connector pins facing your device; to push, install them facing away.

Compact Linear Solenoids
A thin profile allows these solenoids to fit well in narrow spaces. You can use them to push or pull—use the side with the unthreaded rod (R) and two mounting studs to push or use the opposite side with the threaded rod to pull.

Rotary Solenoids
Convert electricity into rotational motion to actuate switches, valves, and locks. These solenoids have a built-in spring that returns the rod to its original position, making them good for use in valves that require precision to fully open or close.
Intermittent-use solenoids are designed to run for seconds or minutes at a time with rest in between. Continuous-use solenoids can operate for hours or days at a time without overheating.

Single-Action Electrically Operated Air Directional Control Valves
These valves create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate. Also known as 3-way and 3/2 valves, they direct airflow from the inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated. Valves without an exhaust connection exhaust air to the atmosphere.
Normally closed valves block airflow until actuated. Valves that are both normally closed and normally open can be installed to block airflow, or allow flow until actuated.
Valves with spring return actuation go back to their original position when voltage is removed.

Electrically Operated Air On/Off Valves
Also known as solenoid valves, these valves actuate when voltage is applied to the electrical connection.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
