Al Spring Check Valve

General Purpose
Aluminum spring loaded check valve allows for you to restrict the flow of fluids to only one direction and also prevent a fluid from flowing when you are not operating with the fluid.

With Solenoid Valves
Check valves can be used in conjunction with solenoid valves to prevent backflow in applications where it is not permitted, since solenoid valves tend to allow small backwards leaks when closed.

WVO Collection
These check valves can also be used to prevent a collection hose from leaking WVO once you have turned off your collection pump. Many pumps require to remain primed, so you can turn off power to the pump before draining the hose, but still maintain oil in the hose without leakage.

Biodiesel
Not suitable for use with biodiesel or methoxide / mixes with lye/potash. All will corrode aluminum rapidly.
