1. A deflator valve for reducing deflation time, comprising a main body (101) having:
a) a plate (104) disposed within the main body (101) to divide an interior into a piston cavity (106) and a valve stem cavity (107);
b) one or more input ports (102) disposed through the plate (104) for fluidly connecting the valve stem cavity (107) to the piston cavity (106), wherein the one or more input ports (102) are skewed such that an entrance and an exit of each input port are offset from one another; and
c) one or more exhaust vents (103) disposed through a sidewall (105) of the main body in the piston cavity (106) for relieving pressure from within the main body.
