The present disclosure relates to an improved pilot valve assembly for a hydrant pit valve. The pilot valve assembly includes a poppet that is movable between an open position and a closed position. The poppet has a molded seal with an interlock feature to hold the seal rigidly. The pilot valve assembly also includes a manually reset mechanism. The reset mechanism can be horizontally positioned and can function to reset the pilot actuator for the next refueling operation. A lanyard can be connected to the poppet to be used a deactuation mechanism.

Pilot valve assembly

A pilot valve assembly, for operating a pressure reducing valve disposed within a fuel tank, can include a housing including a first chamber and a second chamber, a first port in fluid communication with the first and second chambers, the first port being configured to receive an atmospheric pressure, a second port in fluid communication with the first and second chambers, the second port being configured to receive a fuel tank pressure, a first pilot valve arranged within the first chamber and configured to open only when a predetermined positive pressure differential exists between the first and second ports, and a second pilot valve arranged within the second chamber and configured to open only when a predetermined negative pressure differential exists between the first and second ports.
