Valves with Yor-Lok Fittings
- Valve Type: Stem
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: PTFE Plastic
Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.
316 stainless steel valves are more corrosion resistant than brass valves.
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.

Fast-Acting Panel-Mount Threaded On/Off Valves
Open and close these valves with the flip of the toggle switch. Commonly used for equipment testing and gas sampling, they have threads and a hex nut below the handle for installation in instrument panels.
316 stainless steel valves are more corrosion resistant than brass valves.
Manual-return valves remain open or closed when the toggle is moved into position.

Single-Action Air Directional Control Valves
Manually control these valves by pushing or turning the actuator. Also known as 3-way or 3/2 valves, they create one action, such as extending a cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.
Normally closed valves block airflow until actuated.
Valves with hand return actuation stay actuated and go back to their starting position only when you move the actuator again. Valves with spring return actuation go back to their starting position as soon as you release the actuator.
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.
