Two-Action Foot-Operated Air Directional Control Valves
Also known as 4-way and 4/2 valves, these valves create two actions, such as extending and then retracting 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. Valves without an exhaust connection exhaust air to the atmosphere.
Valves with spring return actuation return to their original position as soon you release the actuator.
Valves with a foot return actuation stay actuated and return to their original position only when you step on them again.
Optional safety guards prevent accidental valve actuation.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

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
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 to the atmosphere, allowing equipment to reset so the action can be repeated.

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.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
Optional guards prevent accidental valve actuation. Those that are 6 1/4” high can accommodate safety footwear.

Hands-Free Freestanding Sinks
Step on the pedals for water; release them to stop the flow. These sinks have rounded corners that are easy to clean and resist buildup.
Sinks that meet NSF/ANSI 372 have parts that comply with requirements for lead content when they touch water. They are typically used in food service applications.
Sinks with 0.5 gpm flow rate are useful when water consumption is a concern.
Touch-free faucet kit (sold separately) converts the faucet to a touch-free faucet.
Energy efficiency requirements restrict sales of sinks that cannot be sold to the listed jurisdictions/areas.
