High Flow Check Valves

Unlike other plugs in our product family, A.F.O. Plugs are both removable and reusable due to their threaded design, which allows technicians easy access to sealed passageways. In spite of this, the A.F.O. Plug still seals up to 56,000 psi. Each plug features a floating seal that self-aligns, allowing for threaded holes that aren’t concentric with the through-hole. Lastly, the A.F.O. designation means that no radial force is applied during installation, making this component suitable for thinner-walled housings. See Installation Process Specification P1013 (which applies to all A.F.O. Plugs) for more information.

A.F.O. Plugs are made from stainless steel and are available in standard diameters from 0.190 to 0.625 of an inch.

If you need a check valve that can withstand working pressures up to 15,000 psi and operating temperatures of up to 400°F, The Lee Company offers a solution to fit your needs. These valves are constructed of corrosion-resistant stainless steel and are available with multiple polymeric valve seat material options to achieve zero leakage in the checked direction under extreme hot or cold temperatures.

Lee miniature piloting solenoid valves are the most compact powered components we offer, available in a configuration just 0.875 of an inch in diameter and weighing less than 0.14 lbs. Their threaded bodies are easy to install and maintain and are available for system pressures up to 5000 psi. Meanwhile, the efficient coil design requires power levels as low as 7.8 Watts at 28 Vdc. Many options are available, including a single or dual coil configuration, 2-way or 3-way porting, a normally open or normally closed position, and a customizable electrical interface.
