Often used to detect clogged air filters and iced air conditioner coils, these switches sense small changes in pressure between two points in your duct.

Control six different outputs from a single source of airflow. These valves have one inlet port and six outlet ports. Push in and rotate the dial to move between outlet ports and send airflow to a different output.

Because they require a key to operate, you can limit who is able to adjust these valves. They create one action, such as extending a cylinder.

The push buttons that operate these valves are separate from the logic unit, allowing you to position them away from machinery. Since both hands are required to simultaneously press the buttons, they protect workers from accidental machinery start-up. They create one action, such as extending a cylinder.

Because they require a key to operate, you can limit who is able to adjust these valves. 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 5/2 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.

Since both hands are required to simultaneously press the buttons, these valves protect workers from accidental machinery start-up. 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 5/2 valves, these valves create two actions, such as extending and then retracting a double-acting cylinder. Apply voltage to the electrical connection to actuate.

Run through equipment cycles up to 30% faster than with standard valves. These valves shift between flow positions in 1.7 ms. 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.

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 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. Apply voltage to the electrical connection to actuate.

Run through equipment cycles up to 30% faster than with standard valves. Also known as 3/2 valves, they create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate.

Create two actions at the same time, such as extending two single-acting cylinders at once. Apply voltage to the electrical connection to actuate. Also known as pressure center valves.

Ceramic plates form a longer-lasting seal against oil and dust than rubber seals that deteriorate over time. These valves withstand use in corrosive, dusty, and dirty environments such as foundries, paper mills, and steel plants. Apply voltage to the electrical connection to actuate.

These valves are rated for environments where hazardous material is present. They actuate when voltage is applied to the electrical connection.

These valves create one action, such as extending a cylinder. Also known as 3/2 or pilot valves, they use an air signal to actuate, so they're good for environments where electrical use may be dangerous.

In the off position, these valves stop equipment in a locked position with air pressure holding it in place. 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 actuate by air signal, so they're good for environments where electrical use may be dangerous.

These valves create one action, such as extending a cylinder. Use your foot to operate them, leaving your hands free to perform other tasks. Also known as 3-way or 3/2 valves.

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. Use your foot to operate them, leaving your hands free to perform other tasks. Also known as 4-way and 5/2 valves.

Mix and match valve styles on one manifold to meet your control needs. Mount multiple valves to a manifold to reduce piping requirements and create multiple actions from a single pressure input.

Instead of disassembling your system for inline installation, thread these flow switches onto a mounting adapter and insert them into a pipe tee or pipe outlet. They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate.

Quicker to install than adjustable flow switches in high-pressure lines, these switches come factory-set to activate or deactivate equipment at a specific level. They compensate for the viscosity and density changes of liquid.

UL listed for use where flammable gases or combustible dusts may be present, these flow switches activate or deactivate equipment when your flow rate reaches a set point.

Mount this switch through the top of your tank.
