Corrosion-Resistant Washdown Limit Switches
Rated NEMA 6P, 13, and IP67, these switches are protected from corrosion, oil/coolant spraying, washdowns, and temporary submersion. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used on conveyor systems and bin filling operations.
Styles D and E have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.

Limit Switches
Often used on conveyor systems and bin filling operations, these switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. All are rated IP67 and NEMA 13 for protection from corrosion, oil/coolant spraying, and temporary submersion.

Compact Safety Limit Switches
Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used on conveyor systems and bin filling operations. All are NEMA and IP rated for protection from washdowns.
Styles E and F have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.
NEMA 13 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.

Single-Action Mechanically Operated Air Directional Control Valves
A simple automation solution that requires no programming, these valves are activated when an object, such as a box rolling on a conveyor, pushes the actuator. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their starting position as soon as the actuator is released. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.
Normally closed valves block airflow until actuated.
Valves with a two-direction actuator are activated by objects from both sides.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Two-Speed Two-Action Mechanically Operated Air Directional Control Valves
Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. A simple automation solution that requires no programming, they activate when an object, such as a box rolling on a conveyor, pushes the actuator. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their original position as soon the actuator is released. Also known as 4-way and 5/2 valves.
Valves with a two-direction actuator are activated by objects from both sides.
NPTF (Dryseal) threads are compatible with NPT threads.
