Two-Hand Two-Action Air Directional Control Valves
Since both hands are required to simultaneously press the buttons, these valves protect workers from accidental machinery start-up. Also known as 4-way and 4/2 valves, they create two actions, such as extending and then retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so valves return to their original position as soon as you release the actuator.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Two-Hand Single-Action Air Directional Control Valves
Since both hands are required to simultaneously press the buttons, these valves protect workers from accidental machinery start-up. 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. They can be installed normally open to allow airflow until actuated, or installed to block airflow and until actuated. Return actuation is by spring, so valves return to their starting 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.

Two-Hand Safety Switches
It takes two hands to activate these switches, minimizing the risk of accidental equipment start up. A complete system requires two switches, one safety relay, and two outlet boxes.
Switches meet OSHA requirements and ANSI standards for machine operator safety. They're rated IP64 for protection from splashing water.
Safety relays control the two switches by sending an output signal when both switches are activated within 0.5 seconds of each other. Self-monitoring circuitry offers additional protection—if any part of the system fails, the entire system shuts down until repaired.
Outlet boxes have a drilled hole to fit the switch.
Switch guards protect switches against damage and accidental activation. Use one guard per switch.
