R-431 is a 5 ported, 4-way valve, with spring return and dual pilots. off off off A
When ports 5 and 2 are connected, a momentary pilot signal at port 4 off off on B
will shift the valve to the “latched” position. It will remain in this position off on on B
until the supply (port 1) is removed, or connection between ports 5 and 2 off on off B
is interrupted. on off off A
Special Note: R-431 uses differential pilots and, as a result, the auxiliary
pilot with the spring is not sufficiently large to cancel out the force of pilot on off on A
5. The auxiliary pilot will overcome pilot 4. The valve is actuated by pilot on on off B*
