Safety Lockout Valves for SMC Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)
Prevent accidental start-up when servicing equipment. These lockout valves exhaust downstream pressure and can be locked in the shut-off position using a padlock (not included). Valves help your process comply with OSHA regulations for lockout/tagout procedures.
Joiner clamps (sold separately) connect the safety lockout valve to another SMC modular component with the same series number. They come with mounting brackets to attach the valve to a wall or equipment.
Safety Lockout Valves for Aventics Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)
Keep your air preparation equipment from turning on during maintenance. In their shut-off position, these valves block incoming air and exhaust downstream pressure. You can also lock them closed with a padlock (not included). These valves help you comply with OSHA regulations for lockout/tagout procedures.
Joiner clamps (sold separately) connect these valves to another Aventics modular unit with the same series number. They create compact, airtight connections that are easy to swap out. These clamps come with mounting brackets to attach the valve to a wall or equipment.
Safety Lockout Valves for ARO Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)
Keep air preparation equipment from starting up during maintenance. In their shut-off position, these valves block incoming air and exhaust downstream pressure. You can also lock them closed with a padlock (not included). These valves help you comply with OSHA regulations for lockout/tagout procedures.
Joiner clamps (sold separately) connect these valves to another ARO modular unit with the same series number. They create compact, airtight connections that are easy to swap out. These clamps come with mounting brackets to attach the valve to a wall or equipment.
Safety-Lockout Single-Action Air Directional Control Valves
To prevent accidental start-up, these valves can be locked in their off position with a padlock. 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're normally closed to block airflow until actuated. Return actuation is by hand, so they stay actuated and return to their starting position only when you move the actuator again. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated. They help meet OSHA 29 CFR 1910.147 procedures for the control of energy sources that could injure workers.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Key-Operated Two-Speed Two-Action Air Directional Control Valves
Because they require a key to operate, you can limit who is able to adjust these valves. Often used to extend and then retract a cylinder at different speeds, they 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. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by hand, so they stay actuated and return to their original position only when you move the actuator again. Also known as 4-way and 5/2 valves.
