Abstract

See full text

A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve moveable between a closed-main valve position and an open-main valve position in response to movement of an actuator and a pilot valve moveable between a closed-pilot valve position and an open-pilot valve position in response to movement of the actuator. A configuration of the coupler and the transfer device is coupled together, the coupler valve being in the closed-coupler valve position and the main valve being in the closed-main valve position. A space between a face of the main valve and a face of the coupler valve is minimized to reduce fluid emissions upon uncoupling the transfer device from the coupler.
