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.

Because they require a key to operate, you can limit who is able to adjust these valves.

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.

Tamper-Resistant Air Flow Control Valves
Prevent accidental airflow changes with these valves, which require an adjustment tool (sold separately) to alter their flow rate. Use them to control the speed of air-powered equipment by adjusting the volume of airflow. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control and consistency than inline valves.
Meter out valves control flow as it exits the cylinder. Meter in valves control flow as it enters the cylinder.
Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.
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.

Tamper-Resistant Pressure-Relief Hydraulic Valves
The pressure setting on these valves cannot be adjusted while they are installed. Use a hex key to unlock the locknut and turn the adjustment screw to set the pressure. Valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and fully close when the system pressure is restored below the set pressure.
