Check Valves & One-Way Valves

We offer a variety of one-way check valves for fluid as well as rollover valves for fuel cell vents.

Note: Part Nos. 3605, 3606, and FS TPV06 are the only valves we offer that are spring-loaded to stay closed at rest. All other valves shown here will only close when turned upside-down.

We also offer one-way and flapper valves for Fuel Cell Surge Tanks.

Our low-pressure check valves allow virtually unimpeded flow in one direction, yet the internal flapper prevents flow in the opposite direction. They are used in AN fuel and oil scavenge lines.
