Slide-In Threaded On/Off Valves
Control flow in passageways of manifolds and valve mounting blocks without external pipes. Also known as cartridge valves, they slide into unthreaded holes and secure in place with the included set screw. These valves are ideal for testing and sampling applications because you can quickly open and close them with a toggle or button.
Toggle-switch valves stay open until you flip them closed. Since they don’t need to be held open, they’re often used to dispense large samples. The toggle’s position shows you if they’re open or closed.
Push-button valves open when you press the button. When released, the button springs back and automatically stops flow. They’re ideal for intermittent use and controlling flow to avoid spills.
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.

Single-Action Electrically Operated Air Directional Control Valves
These valves create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate. Also known as 3-way and 3/2 valves, they direct airflow from the inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated. Valves without an exhaust connection exhaust air to the atmosphere.
Normally closed valves block airflow until actuated. Valves that are both normally closed and normally open can be installed to block airflow, or allow flow until actuated.
Valves with spring return actuation go back to their original position when voltage is removed.
