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. They activate when an object, such as a box rolling on a conveyor, pushes the actuator. Also known as 4-way and 5/2 valves.

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 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. Also known as 4-way and 5/3 closed center valves.

Control these valves with one hand. Also known as 4/2 valves, they create two actions, such as extending and then retracting a double-acting cylinder.

In the off position, these valves exhaust all air pressure, allowing the equipment to return to the neutral position. Also known as 4/3 exhaust-center valves, they create two actions, such as extracting and then retracting a double-acting cylinder.

Also known as 4-way and 5/3 pressure center valves, these valves create two actions at the same time, such as extending two single-acting cylinders at once.
