Washdown Foot Switches

Stainless Steel

Iron with Guard

Iron with Oversized Guard

Three-Prong Outlet

These switches meet requirements for protection from washdowns.

IP67 rated switches protect against temporary submersion.

NEMA 13 rated switches are protected from oil/coolant spraying.

Two-speed switches have staged contacts. For slow speed, push the pedal halfway to close the first contact; for high speed, push it all the way to close the second contact.

Switches with front pivot reduce user fatigue.

Switches with a three-prong outlet let you plug a device directly into the switch.

Switches with an oversized guard accommodate bulky footwear.

Switches with a safety lever prevent accidental activation; the lever must be pushed forward before pressing the pedal.

Two-Speed Two-Action Foot-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. Operate them with your foot, leaving your hands free to perform other tasks. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. The foot guard prevents accidental valve operation. Also known as 4-way and 5/2 valves.

Valves with spring return actuation go back to their original position as soon as you release the actuator.

Valves with a foot return actuation stay actuated and go back to their original position only when you step on them again.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Single-Action Foot-Operated Air Directional Control Valves

One Valve

Two Valves

Also known as 3-way or 3/2 valves, these valves create one action, such as extending a cylinder. Use your foot to operate them, leaving your hands free to perform other tasks. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to normally block airflow, and remain closed until actuated. Return actuation is by spring, so they go back to their original position as soon as you release the actuator. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Foot-Operated Air On/Off Valves

Turn airflow on and off with your foot to keep your hands free to perform other tasks. Step on the valve to allow airflow; release the valve to stop the flow. The nonskid base prevents the valve from slipping.
