Air-Operated Air On/Off Valves
Also known as blocking valves, these valves are activated by an air signal to turn equipment on and off. They allow airflow when an air signal is applied to the air pilot. When the air supply is removed, the valve closes, trapping air in the system.
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.

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

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.

Attach gauges or sensors to these valves so you can remove them for maintenance and calibration without depressurizing your line. Also known as block and bleed valves, turn the handles to block both upstream and downstream flow, drain the liquid trapped in the valve through the bleed port, and then remove your instrument from the gauge port. Often used in chemical-processing lines, these valves have a PEEK seal and a corrosion-resistant 316 stainless steel body. All are standard port, so they slightly restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
